4 Blog, Hair loss | Dr Dhanraj Chavan | October 20, 2022 The hair growth rate per day and month of the year is based on several factors like genetics, age, hormonal levels, and overall health. We are born with about 5 million hair follicles out of which 100,000 follicles are on the scalp.
Follicles on the scalp go through active and inactive phases, thus affecting new hair growth and the growth rate. As stated earlier, one’s genes are among the prime factors that determine how fast the hair grows. The hair growth rate also varies based on gender, meaning that hair growth in males is faster than that in females.
The hair growth rate is the maximum between the age of 15 and 30, after which people commonly experience hair thinning or even baldness. Hormonal balance, a healthy diet, exercise, and stress management are other important factors that are necessary to maintain a healthy hair growth rate.

How long does it take for hair to grow?
Does hair grow 1 cm per month?
How fast hair grows can vary for each person. On average, hair tends to grow between 0.5 and 1.7 centimeters per month. This is equivalent to around 0.2–0.7 inches. This estimate comes from The Trichological Society, However, lots of different factors affect the speed of hair growth.
Males, for example, may find that their hair grows faster than that of females. Other things that influence the speed of hair growth include genetics, age, health, and pregnancy. Bone marrow, which is the soft substance present inside the bones, is the only part of the body that grows faster than hair.
The lips, palms of the hands, and soles of the feet are the only parts of the body on which hair does not grow. The main purpose of hair is to protect the body and keep it warm. Keep reading for more information on how hair grows and the various factors that affect the speed of its growth.
- Each follicle contains a hair root, which is made of cells of protein.
- As blood circulates around the body, it delivers oxygen and nutrients to the protein cells, which they need to multiply.
- As the protein cells multiply, they build hair, which pushes up through the skin.
- As the hair grows out of the skin, it passes an oil gland. This lubricates the hair with the oil it needs to stay soft and shiny.
- By the time the hair is long enough to come through the skin, it is dead. As a new hair grows underneath, it pushes the dead hair out of the skin. The hair then falls out or is shed.
Not all hair follicles are in action at the same time. Follicles on the scalp, for example, will grow hair for a few years before becoming inactive for a period. This inactive part of the hair growth cycle is called telogen. People lose around 50–100 hairs from their body every day as part of the normal hair growth cycle.
- Genetics : A person’s genes will dictate how quickly their hair will grow.
- Sex : Male hair grows faster than female hair.
- Age : Hair grows fastest between the ages of 15 and 30, before slowing down. Some follicles stop working altogether as people get older. This is why some people get thinner hair or go bald.
- Nutrition : Good nutrition is essential for the growth and maintenance of healthy hair.
Telogen effluvium occurs when stress prompts the hair roots to enter the telogen stage of the hair cycle too early. It can mean that as many as 70% of scalp hairs fall out within about 2 months. People experiencing telogen effluvium often find that their hair comes out in handfuls.
- high fever
- severe infection
- severe illness
- overactive or underactive thyroid gland
- not eating enough protein
Several medications can also cause telogen effluvium. These include:
- calcium channel blockers
- nonsteroidal anti-inflammatory drugs such as ibuprofen
Telogen effluvium will usually clear up on its own once a person has sought treatment for the cause. According to the American Osteopathic College of Dermatology, the amount of shedding tends to decrease over a period of around 6–8 months. Learn more about telogen effluvium and its treatment here.
- According to The Trichological Society, there is little evidence to suggest that using special shampoos or taking supplements can make hair grow any quicker.
- Good nutrition is an important part of healthy hair growth.
- This is because the living part of the hair (the root) receives its nutrients from the blood.
Adopting a healthful diet containing fruit, vegetables, grains, and an appropriate amount of fat will promote healthy hair. Specific foods that can promote healthy hair include:
- Fish : Fish contains essential omega-3 fatty acids, protein, vitamin B-12, and iron, all of which prevent a dry scalp and stop hair from looking dull in color.
- Dark green vegetables : These contain high levels of vitamin A and C, which help keep hair in good condition.
- Legumes : These are full of protein, which promotes hair growth and helps prevent weak and brittle hair.
- Biotin : A biotin deficiency can lead to brittle hair or hair loss, Whole grains, liver, egg yolk, soy flour, and yeast all contain biotin,
- Nuts : These are a good source of selenium, which is important for a healthy scalp. Some nuts also contain alpha-linoleic acid and zinc. These help condition the hair and prevent shedding.
- Low fat dairy products : These are good sources of calcium, which is another key component in hair growth.
Everyone’s hair grows at different rates. Many factors — including genetics, sex, and age — can influence the speed of hair growth. Hair grows out of follicles, which are small pockets inside the skin. Each follicle contains a hair root, which is made of protein cells.
How fast does hair grow in CM?
1. How fast does hair grow? – 1.1 How many centimeters is your hair a month? According to the American Academy of Dermatology (AAD – American Academy of Dermatology), the average hair length will be about 1-1.5cm per month, and in a year, the hair will be about 15-20cm long.

- These three phases are: Anagen: The active hair growth phase lasts 2-8 years Catagen: The transition phase when hair stops growing, lasts 4-6 weeks Telogen: The resting phase when hair falls out, lasts 2-3 months The average scalp has 90-95% of hair follicles in the anagen phase.
This means that about 5-10 percent are in the telogen phase, which accounts for 100-150 hairs that fall out each day. Tóc phát triển theo ba giai đoạn và mỗi sợi tóc sẽ theo dòng thời gian riêng How long the anagen phase lasts depends on the length of your hair and whether the cells in your hair follicles are continuing to multiply and become hair cells. Researchers are still studying what triggers our bodies to “turn on” the anagen phases.
But there are things you can do to promote healthy hair during the anagen phase. There are a number of factors that can affect hair growth, including: Genetics or family history of hair loss Hormonal changes Nutritional deficiencies Stress Trauma that damages hair follicles Medical conditions or other condition.

Avoid pulling your hair tightly with elastics, clips, hairbands, or any other accessories that put stress on your roots. Otherwise, it may lead to hair loss. While genetics does play a role in hair growth, several other factors also come into play. And while there’s no magical formula for instant hair growth, there are steps you can take to boost the health and growth of your hair.

Does trimming hair make it grow faster?
We’ve all heard that trimming your hair will make it grow faster, but doesn’t that seem counterproductive? How can cutting your hair shorter make it grow longer? Today, we are here to explore that statement and explain what it really means. The quick answer to “does trimming hair make it grow faster” is no, it doesn’t.
Hair growth starts at the scalp, so trimming off the dead ends doesn’t actually make it grow faster. However, it makes it grow healthier, which is crucial if you want long luscious hair. Cutting split ends and damaged hair helps your hair to appear healthier and thicker and prevents split ends from traveling up the hair shaft.
So now we know trimming our hair makes it grow healthier, but how often do we need to do it? Regularly getting a trim is a part of keeping your hair healthy, and the frequency depends on your hair type and hairstyle. If you have textured hair, you’ll want to trim your hair every 2-3 months to keep it soft and healthy.
Can hair grow 1 inch a week?
Typically, hair grows an average of about half an inch each month. This means hair grows about 1/8 of an inch each week, and you can expect your hair to grow one-and-a-half inches in three months. At any given time, the hair on your body is in different phases of growth.
The majority of your hair is actively growing while some of your hair is in a resting, non-growing phase, and some of your hair is naturally being lost. Hair grows for about six years before it falls out, and it’s normal to lose about 100 hairs each day. Most humans have an average of two to five million hair follicles.100,000 of these follicles are located on the head, and the rest are distributed on the arms, legs, face, chest, and elsewhere.
Caucasians with light hair generally have higher hair density than Caucasians with darker hair, meaning they have more hair follicles per square inch. Caucasians in general tend to have higher hair density than people of African or Asian descent. At any given time, your hair is in various stages of growth.
Anagen phase: When your hair is actively growing; about 90% of your hair is in this phase. Catagen phase (regression phase): When your hair slows in growth and becomes detached from the shrinking follicle; 10% or less of your hair is in this phase. Telogen phase (resting phase): When your hair is neither growing nor shedding; 5-10% of hair is in this phase Exogen phase (shedding phase): When your hair naturally falls out of the follicle.
In your lifetime, each individual follicle will go through this cycle about 10-30 times. The anagen phase (growth phase) lasts between two and eight years, which means this is how long a hair will continue to grow on your head. However, growth in other areas of the body may be shorter.
For example, the growth phase for eyebrow hair is only two to three months. The rate at which hair grows and is lost can vary based on factors such as your age, medical conditions, and how you care for your hair. Healthy, young hair usually grows about half an inch each month, and is lost at a rate of about 100 hairs a day.
Many factors can affect hair growth and how fast your hair grows. Your hair growth may speed up at times and slow down at other times. Sometimes hair growth slows down substantially, or hair is lost and not replaced. Although hair loss or slowed hair growth is not life threatening, it can affect your self-esteem, mental health, and quality of life.
Does hair grow in 20 days?
What factors affect the rate at which hair grows? (Image credit: Getty Images) Healthy human hair grows at an average rate of 0.01 inch (0.35 millimeters) per day, which adds up to roughly 0.5 inch (13 mm) per month, or 6 inches (15 centimeters) per year, according to the medical resource StatPearls,
However, this commonly cited rate of hair growth applies mostly to white people. The hair of people of other races, such as those of Asian or African descent, tends to differ from the hair of white people in several ways — for example, in its density (how closely hair strands are packed together), the angle at which hair grows, and even the overall growth rate, according to a 2005 study published in the International Journal of Dermatology,
In people of African descent, hair tends to grow around 0.2 inch (5 mm) per month, whereas Asian people’s hair often grows much faster, at up to 0.8 inch (20 mm) per month, Sally-Ann Tarver, a trichologist at Cotswold Trichology clinic in England, told Live Science by email.
Racial differences in hair growth rate appear to be determined by genetic factors, rather than environmental factors, according to a 2016 study published in the European Journal of Dermatology, It should be noted, however, that hair growth does not occur at a steady rate in anyone, regardless of their race.
There are three primary phases of the hair follicle cycle: anagen, catagen and telogen. Most hair growth occurs during the anagen phase, which can last anywhere from two to six years. It slows down during the catagen phase and then completely stops in the telogen (resting) phase.

What does 1 year of hair growth look like?
Whether you’re suffering from a particularly unfortunate haircut or you’re just ready to change your style, you may be eager to grow your hair faster. So, how much does hair grow in a year? You can expect about 6 inches of hair growth each year. Continue reading to learn more about how hair growth works and what you can do to set yourself up for lustrous success.
- Anagen (growth phase) : Your hair is actively growing during the anagen phase. This phase can last for several years. So, you have the anagen phase to thank for your hair growth over the course of a year.
- Catagen (transition phase) : The catagen phase occurs when your hair is ready to stop growing. It lasts for a few weeks and prepares your hair for the telogen phase.
- Telogen (resting phase) : During the telogen phase, your hair is at rest and does not grow. At one time, around 10–15% of the hairs on your head are in this resting phase. This phase can last for up to one year.
Hair loss can occur when the hair growth cycle is interrupted. For example, one type of hair loss called telogen effluvium (TE) leads to the shedding of telogen, or “resting,” hairs. It can be caused by various factors, including stress, dieting, nutritional deficiency, toxins, medications, illness, and even too much exercise.
- Basically, anything that shocks the body can trigger TE.
- Fortunately, the hair eventually regrows ( Al Aboud, 2022 ).
- The most common type of hair loss is androgenic alopecia, which affects all people (male pattern hair loss and female pattern hair loss) and is mainly linked to genetics and hormones.
This type of hair loss typically does not regrow on its own. For this reason, studies suggest it’s easier to prevent hair loss than regrow it later (Al Aboud, 2022). Paying attention to your hair growth for a full year is a good way to check for hairline changes,
It’s also enough time to try out new techniques to improve hair health and see what works and what doesn’t. There’s nothing like a bad haircut to make you daydream about how to make your hair grow faster. While you may not be able to force the hair growth process to speed up, you can make changes to ensure your hair is healthy, and therefore less prone to breakage.
Here are 10 tips to improve your hair health over the next year: Hair health begins from within. The best approach to getting the nutrients your hair needs–such as protein, iron, zinc, vitamin C, and hair-healthy omega-3s –is to eat them. Eating a balanced diet full of healthy proteins, fats, fruits, and vegetables offers the best building blocks for healthy hair ( Guo, 2017 ).
- Lots of supplements claim to boost hair health.
- Nutrients like biotin, omega-3 fatty acids, vitamin C, and vitamin D are important for hair health.
- However, research shows supplements are not needed unless you have a vitamin deficiency,
- Most people get enough biotin, zinc, vitamin A, and other nutrients in their diets ( Almohanna, 2019 ).
You should always consult your healthcare provider before taking any supplements. Iron and vitamin D supplements are commonly prescribed to offset deficiencies. But, overdosing on vitamins, especially iron, can be dangerous. Your healthcare provider will help determine if you have any vitamin deficiencies (Almohanna, 2019).
- If you smoke, quitting may help you boost hair growth.
- Studies show that pattern hair loss (and hair loss in general) is more common in smokers than in nonsmokers ( Babadjouni, 2021 ).
- Studies have shown stress can lead to hair loss,
- Hair loss, in turn, can lead to more stress,
- To break this cycle, experts suggest finding ways to reduce stress, like engaging in meditation, exercising regularly, prioritizing sleep, or cozying up with a pet or loved one.
These stress-reduction techniques will not only help your body and mind, they may also help your hair as well ( Hadshiew, 2004 ). Avoiding harsh hair care products like chemical relaxers, perms, and dyes can help prevent hair follicle damage and hair breakage.
- Healthier scalp and hair follicles grow hair strands that are less likely to break off ( Dias, 2015 ).
- Heavy heat styling, straightening, and tight hairstyles (like braids and ponytails that pull on the hair ) can damage hair and hair follicles.
- Data suggests more damage and thinning in heavily styled hair.
That said, if you don’t want to skip the styling, ask your stylist for products that can help protect your hair shafts from heat ( Malkani, 2020 ). Using a conditioner can help seal, hydrate, and protect your hair. In addition, conditioners make your hair shinier and easier to comb.
This can help cut down on hair breakage, especially if you have long hair. Combing out tangles can pull on the hair follicles and lead to split ends. Different hair types may benefit from different types of conditioners, so ask a stylist if you’re unsure of what type of conditioner your hair needs (Dias, 2015).
Wearing a hat or scarf when you’re out for long periods in the sun can help prevent ultraviolet (UV) radiation from damaging your scalp, hair shafts, and hair follicles. Protecting your scalp can keep your hair in peak shape for hair growth ( Gherardini, 2019 ).
Scalp massages are relaxing and may increase blood circulation to hair follicles. One study of more than 300 men with male pattern baldness found that almost 70% of men who committed to scalp massage reported that their hair loss stopped or they noticed hair growth. The scalp massage sessions in the study were twice a day for 20 minutes for 10 months ( English, 2019 ).
But more research is needed. If you notice hair thinning rather than hair growth, Ro can connect you with healthcare providers who can recommend over-the-counter or prescription medications to help treat your hair loss. Minoxidil (brand name Rogaine ) is a topical OTC medication (a liquid or foam medication rubbed on the scalp) that can help promote hair growth and is FDA-approved to treat hair loss in all people ( Badri, 2021 ).
- It can take about four months of continuous use to see results with minoxidil.
- Finasteride (see Important Safety Information ) is an oral prescription medication that is approved to treat biological men with androgenic alopecia (APA).
- But biological women with female pattern hair loss (FPHL) who are not pregnant and are not planning to become pregnant may be prescribed finasteride off-label.
Women who are pregnant, however, should not touch any broken tablets because of the risk of harm to a fetus. ( Iamsumang, 2020 ). You can also take finasteride and minoxidil together. Studies suggest that taking minoxidil and finasteride together improves results ( Chen, 2020 ).
- Yes, you can take finasteride for a year.
- In fact, the best finasteride results are typically reached within a year.
- Finasteride works by preventing the conversion of testosterone into dihydrotestosterone ( DHT ), a hormone that plays an important role in male pattern hair loss.
- Finasteride continues to help prevent hair loss as long as you use it.
When you start the medication, it’s normal to see more hair loss in the first few months. New hair growth is usually noticeable by the third or fourth month of treatment, and even more noticeable by month six. Often people take finasteride for a year or more ( Zito, 2022 ; Shin, 2019 ).
- Finasteride’s side effects include decreased sex drive, erectile dysfunction, and gynecomastia (male breast enlargement) (Zito, 2022).
- Yes, you can take minoxidil for one year,
- It maintains its effectiveness while it’s being used, and is considered safe for long-term use.
- Minoxidil comes in a foam or liquid that’s applied to the scalp and is believed to help stimulate hair growth by boosting blood flow and nutrients to hair follicles.
Similar to finasteride, minoxidil may trigger some hair shedding at first in some people. This shedding is telogen hairs that are released as minoxidil pushes the follicle into the anagen phase. Not everyone experiences hair shedding, and shedding can be reduced by using the lower 2% topical solution versus the 5% solution (Badri, 2021).
- You should begin to see results after about eight weeks of consistent use.
- After about four months of treatment, new growth takes over, and hair loss decreases.
- Results vary and depend on the extent of your hair loss.
- If you have telogen effluvium, once you’ve addressed what triggered it, minoxidil may be able to help with regrowth (Badri, 2021).
Topical minoxidil side effects include some skin irritation and hair shedding. Additionally, misapplying minoxidil can lead to hair growth on the face ( Sattur, 2021 ). There are many ways to improve hair health and growth. If you’re experiencing hair loss, Ro can help,
Your provider can help come up with a treatment plan that’s safe and effective for you. If you have any medical questions or concerns, please talk to your healthcare provider.

Can you grow 2 cm of hair in a month?
Growth cycle – 0:27 Hair-follicle cycling Hair grows at different speeds and different lengths. Its composition causes different colors and textures, which influence how long the hair strands grow. Marianne Ernst, a German “Long hair model”. The three stages of hair growth are the anagen, catagen, and telogen phases. Each strand of hair on the human body is at its own stage of development. Once the cycle is complete, it restarts and a new strand of hair begins to form. The growth rate of hair varies from individual to individual depending on their age, genetic predisposition and a number of environmental factors. It is commonly stated that hair grows about 1 cm per month on average; however reality is more complex, since not all hair grows at once. Scalp hair was reported to grow between 0.6 cm and 3.36 cm per month. The growth rate of scalp hair somewhat depends on age (hair tends to grow more slowly with age), sex, and ethnicity. Thicker hair (>60 µm) grows generally faster (11.4 mm per month) than thinner (20-30 µm) hair (7.6 mm per month). It was previously thought that Caucasian hair grew more quickly than Asian hair and that the growth rate of women’s hair was faster than that of men. However, more recent research has shown that the growth rate of hair in men and women does not significantly differ and that the hair of Chinese people grew more quickly than the hair of French Caucasians and West and Central Africans. The quantity of hair hovers in a certain range depending on hair colour. An average blonde person has 150,000 hairs, a brown-haired person has 110,000, a black-haired person has 100,000, and a redhead has 90,000. Hair growth stops after a human’s death. Visible growth of hair on the dead body happens only because of skin drying out due to water loss.
