Why Does My Hair Grow So Fast?? Read This To Learn!

Why does some people’s hair grow so fast? How fast does hair grow? How can I stop my hair from growing so fast? Why does my hair grow so fast after shaving? Why does my hair grow so fast female?

There never were in the world two opinions alike, no more than two hairs or two grains; the most universal quality is diversity” 

(Michel de Montaigne, 1533-1592)

One of the factors that make up the beauty of a woman is her hair, especially long hair. But it takes several years for the hair to grow back, as it only adds a few millimeters to the length of the hair in a month.

Hair growth cycles

Throughout human life, hair goes through three cycles: growth, rest, and loss. The first phase lasts from two to five years, the second phase lasts two weeks, and the third phase lasts about three months. During the extinction phase, the hair stops developing, at this stage its follicle shrinks and moves closer to the skin surface, after which the hair falls out. A new hair begins to grow in place of the hair that has fallen out. Thus, over and over again, the hair growth cycle is repeated.

It was found that hair grows faster during the daytime, as well as in hot climates, and in spring and summer. At this time, hair growth is accelerated by 15-20%. This happens because when heat, blood circulation in the scalp increases. Due to this, the hair follicles are better penetrated by nutrients. At the same time, during the cold season, blood begins to circulate more strongly in the internal organs, but near the dermis blood movement slows down. For the same reason in winter, the hair cells are not so actively divided.

The growth rate of hair is also directly dependent on age. Thus, children’s hair grows by 1.3 centimeters on average per month, adults – 1.5 centimeters, and elderly people – about 1 centimeter.
It should be noted that the speed at which hair grows also depends on heredity.

Girls, you should take note! As scientists note, hair growth slows down by 0.5 centimeters per month after dyeing, as well as chemical curls.

How hair grows to

Hair, on the scalp as well as elsewhere, grows from tiny pockets in the skin called follicles. Hair starts growing from the bottom of the follicles called the root, which is made up of cell healthy proteins. These healthy proteins are fed by blood vessels that dot the scalp. As more cells are generated, hair starts to grow in length with the skin, passing an oil gland along the way. Arising from the pit of each of these follicles is the hair shaft itself. By the time it’s long sufficient to jab out with the skin, the hair is currently dead, which is why you can not feel anything when you obtain your hair cut.

Reasons that Your Hair Grows So Rapid

There are various factors for quick hair development, yet fortunately is that none of them are signs of disease.
As a matter of fact, for most individuals that are experiencing this for the first time, this could indicate that you are doing something right for your body. Below is a checklist of one of the most typical reasons for fast hair growth:

1. Hormonal agents

On average, human hair can grow up to 6 inches annually. Most of the time, hair development has little to do with the products we make use of, yet more about one’s hormonal agents.
For women that have observed a rise in hair growth, particularly in locations where the hair is supposedly sporadic, this could mean that she has more male hormonal agents specifically testosterone or androgens.
Typically, this is not something that seriously affects one’s wellness. However, if this sign comes with other stressing elements, you should visit your doctor to review it. Your hair growth may be the impact of a hormone inequality issue.

2. Blood circulation

Science states that frequent cleaning improves blood circulation for your hair follicles.
With good blood flow, your hair follicles are healthy and balanced adequately to deliver nutrients to your hair. Rubbing your hair often can also contribute to great blood flow. Intensively dividing hair follicle cells need a constant supply of essential nutrients (vitamins, amino acids, and trace elements), growth factors, and hormones. The scalp has a much more active blood flow than the rest of the body. Let’s remember how strong the bleeding can be when the scalp is injured. The reasons for this are as follows: blood enters the scalp through several arteries that freely merge inside the layer of dense connective tissue located under the skin. The walls of blood vessels are “soldered” with connective tissue fibers and are not able to contract, thereby maintaining constant good blood flow in the scalp. However, there are conditions that can lead to impaired microcirculation and contribute to the aggravation of hair loss (for example, psycho-emotional stress, inflammation of the scalp, mechanical compression of the skin). Here are some recommendations that help improve microcirculation.

If this is you, this most likely means that you are doing something right for both your body and your total wellness.

3. Healthy Protein and Biotin Consumption

Your hair is made out of healthy protein. It only makes sense that if you are taking in a great deal of healthy protein from your diet regimen or with healthy protein drinks, your hair will certainly expand faster than usual.

The same goes for biotin. There are many hair items around that contain biotin, especially for advertising hair development. Examine your shampoo containers to see if your hair shampoo is the reason.
Nevertheless, this does not imply that you should stop consuming healthy protein. Protein is very good for your health, and also needs to be remained to attain optimal health and wellness there is no reason for you to prioritize slower hair growth over your hair.
What you may want to do is to lessen your dose right into a better-suited quantity. But health is more important! therefore, we do not refuse protein!

Here is the average growth rate of hairs on different parts of the body, according to data found in a research paper by Pragst F. Balikova, MA.

Part of Body           Average Growth Rate (mm per day)

  1. Scalp, non-bald      0.32–0.46
  2. Scalp, alopecia  0.08–0.15
  3. Beard  0.25–0.29
  4. Underarm  0.29–0.33
  5. Pubic Area  0.3
  6. Eyebrow   0.15–0.16
  7. Thigh   0.13–0.25
  8. Trunk/Arms/Legs   0.27
  9. Forehead   0.03

Straightforward Tips To Quit Hair From Expanding Also Rapid

Now that you know that boosted hair development is a great and healthy and balanced thing, I hope that you do not think of it because of an adverse thing anymore. Nevertheless, I recognize that keeping hair expanding at hastened rates can be meddlesome.

Since hair growth is directly related to your health, we will not advise you to stop taking vitamins or eating less protein.

Below are some ideas you can follow:

  1. Сut your hair on the waning moon, especially in the fourth quarter of the lunar calendar. However, not all so simple. In addition to the speed of hair growth, there are other factors that influence the choice of the best lunar day for a haircut. Do not forget that every lunar day corresponds to a certain part of the human body, activates certain organs. Astrologers advise avoiding direct exposure to the organ on that lunar day, which activates it. Therefore, the haircuts lunar calendar excludes days corresponding to the organs of the head and skin. So, 5 and 22 days of the lunar cycle are unfavorable for hair cutting. In addition, there are some days of the Moon phase’s change in the lunar cycle. Generally, such days are considered as unfavorable and even satanic in some esoteric schools. In fact, these days of the lunar cycle – 9, 15, 19, and 29 – are simply characterized by a very powerful flow of lunar energy, which not all people can cope with. Therefore, do not forget that the hairdresser is also a human. It is better not to visit him on unfavorable lunar days.
  2. Use a hair growth inhibitor cream
  3. Сheck hormone levels – if the problem has reached a high status

At the end of the day, hair growth is still a bit of a mystery to scientists and skin experts alike, so no one solution will work for everyone. “We are learning more about how hair growth is controlled at a cellular level, but scientific evidence on how to speed up hair growth directly is still lacking, so certain methods have not been rigorously studied,” said cosmetic dermatologist Dr. Sejal Shah, founder of SmarterSkin Dermatology.


Hair growth rates vary significantly between ethnicities. In a large study on the diversity of human hair growth, people of African descent tended to have hair that grew the slowest as well as the thinnest hairs. People of Asian descent had hair that tended to grow the fastest along with the thickest hairs. And people of European descent fell in the middle. Here’s a chart from that study showing the diversity in hair growth speeds. However, as I cover in the next section, this may be more about hair thickness than ethnicity.

Hair Thickness

In a study of Asian and Caucasian subjects with straight and semi-straight hair, thicker hair fibers corresponded to a faster growth rate. Thin hair fibers had slow growth rates. This finding appeared to be unrelated to ethnic origin.

Another study analyzed 59,765 hairs and found that thin hairs grew slower than thick hairs. This may explain why Asian people tend to have hair that grows the fastest. They also have the thickest hairs. If you have thick hair, that explains why your hair is growing so fast. However, just because your hair seems thick doesn’t necessarily mean that it is actually is thick. Especially if you are of European descent, you may just have dense hair. That means you have more hair follicles spaced close together and a lot of hairs, but they aren’t necessarily thick. You can tell if your hair is thick by pinching an individual hair between your fingers and feeling it. If you feel nothing between your fingers, you don’t have thick hair. If instead, your hair feels like some heavy sewing thread, you have thick hair.


First of all, you need to understand what affects the speed of hair growth. Rapid hair growth can be associated with a number of reasons. This may be inherent in a person genetically. Recent research by Russian geneticists has identified a gene that controls hair growth. Although further experiments are needed to develop therapeutics to control hair loss and growth, existing results have shown that this gene plays an important role in regulating hair growth. It is a gene for phospholipase, an enzyme that produces biologically active lipids. Both the enzyme and the chain of metabolic reactions in which it is involved are the main goals of future research.

So what if everything is decided by genetics, then it is impossible to accelerate or reduce hair growth? You shouldn’t get upset right away, because our hair almost never grows at the maximum speed that nature has put in it. This may be due to insufficient intake of substances necessary for hair growth, due to existing endocrine and gastroenterological diseases, diseases of the hair bulb itself. Finally, slow hair growth can be caused by improper hair care.

To find out the exact cause of hair problems, it is better to consult a specialist – the doctor-trichologist. After performing the necessary tests, he will identify the cause of slow or rapid hair growth. If the cause is the existing internal diseases, then after their treatment the problems with hair can be solved by themselves. Slow hair growth, provoked by an insufficient amount of necessary nutrients, can be corrected by making changes in the diet.

Expert advice on hair growth care

Good: when choosing hair care products, pay attention to professional care based on natural components, in such brands powerful laboratories that work for perfect quality.

Good: use special products to accelerate hair growth. For example, Biolage’s FullDensity line contains the Stemoxidine molecule (which activates hair growth) in the highest concentration in the vials of the same name – FullDensity.

Good: choose a shampoo according to the type of scalp, for example: quickly polluted – in Biolage Scalp Syncline a normalizing shampoo will be the best choice or in Biolage R.A.W. line. Scalp Care.

Good: use the service of hair detox in Biolage beauty salons. It gently cleanses the scalp from chemical preservatives that can prevent healthy hair growth!

Bad: create your own care from plant components according to ancient recipes, they may not show positive effects, but may also harm the lipid layer of the scalp. Tip: entrust the scalp diagnosis to professionals who will individually select the care and service in a beauty salon!

Bad: use products from the mass market; they are certainly suitable for maintaining hair quality, but if you want to improve the quality of your hair, you should contact professional brands such as Biolage and Biolage R.A.W.

Bad: Pour shampoo and other scalp care – all washable scalp products are applied with your hands: if it’s a shampoo, lather it up in your hands and massage it over your skin, so you’ll protect your scalp from dryness and irritation. The Biolage Scalp Sync and Biolage R.A.W. Scalp Care lines are suitable for hydrating your scalp.

Also, don’t forget the general tips for anyone who wants to see their hair healthy and well-groomed.

  • Cut off your tips more often (the recommended frequency of salon visits is once every 8 weeks).
  • Always use conditioner, preferably the same brand and series as the shampoo.
  • Do not forget about masks and use hair oils.
  • Rinse your hair with cool water.
  • Do not wear a towel on your hair after washing your hair – this will cause it to break.
  • Use silk and satin pillowcases to minimize static electricity and change the pillowcase once a week.
  • Do not use combs with a metallic nap.
  • Try to collect hair less often in a ponytail and do not use tight rubber bands.
  • Use a hairdryer and iron less often.

Which vitamins have a beneficial effect on the hair

Not all vitamins are equally useful. The condition of the scalp improves:
Vitamin H. Lack of this vitamin leads to most scalp problems, and as a result, worsens the condition of the hair. Seborrhea, eczema, hair loss – all this is a consequence of vitamin H deficiency.
Vitamin B2. Its deficiency leads to the worst variant of combined hair: at the roots, it will quickly become dirty, and at the tips, it will become dry and brittle.
Vitamin B3 normalizes the blood microcirculation, making the hair brighter.
Vitamin B5. Helps to get rid of itchy scalp and repairs damaged hair.
Vitamin B6. Protects against dermatitis and diathesis, and its lack in the body leads to dandruff.
Vitamin B9 helps effectively renew the hair structure. It is responsible for the synthesis of new cells.
Vitamin B12 affects the process of cell division, provides the scalp with oxygen.
Vitamin A (or retinol) normalizes the sebaceous glands.
Vitamin E nourishes the hair. It makes the hair brighter and stronger. In combination with vitamin A, it is an effective revitalizing agent for all types of hair.
Vitamin C protects the hair from free radicals, ie protects the scalp from aging and dryness.
Vitamin F effectively reflects the negative effects of the environment.
Vitamin PP moisturizes and nourishes the hair.
Vitamin D – eliminates peeling, promotes the absorption of calcium, the most important element for the health of hair.

Final Takeaways

If you have fast-growing hair, the main reason is your DNA and hair thickness. Several other things, like environmental factors, age, stress, and medications may have an impact, but your DNA mostly calls the shots in this department. Why does my leg hair grow so fast?  The reasons are the same.
