Lifecycle of Hair

What Is The Lifecycle Of Hair?

Lifecycle of Hair

Your head is made of thousands of strands of hair and up to 100,000 hairs for a healthy scalp. Each strand is in a different stage when it comes to the 2 to 8-year lifespan.

Hair typically grows and then finally dies over different phases, and stress, hygiene, daily styling, and nutrition all contribute to the amount of hair that you lose daily.

The anagen phase is when the hair strands are still growing, and 90% of the hairs on your head are in this phase. During the "anagen" phase, the strands grow around 1 centimeter every month. If something is stopping or interfering with hair growth, it is known as "anagen effluvium." Anagen effluvium is something that you would naturally assume when thinking of "hair loss."

The next stage is known as the catagen phase. Only around 1 to 2% of the hairs on your head will be in this phase. This is a stage that lasts between 2 to43 weeks, where the hair stops growing.

The final phase is called the "telogen phase." The hairs in this phase are also known as "club hairs." In this final stage, the strands are at rest while preparing to fall out (detach from the scalp). Only around 8 to 9% of the strands will be in this stage at a time.

Telogen effluvium occurs when over 10% of the hair on your head is in this final stage. Telogen effluvium is only temporary, but you will notice more hair loss while your hair is in this phase. Surgery, stress, or even experiencing a high fever over a day or two can result in telogen effluvium. Your hair will most likely normalize within 6 months.

Why Is My Hair Falling Out?

Moderate hair loss every day is normal. But an increase in the hair that is falling out may have to do with a health condition or stress. Other reasons why hair loss occurs include:

  • Nutritional deficiencies
  • Alopecia
  • Lupus
  • Female Pattern Hair Loss
  • Thyroid Conditions
  • Excessive heat styling, brushing, bleaching, and washing can also contribute to how many hairs fall out each day. Once the hair follicles are split or stretched, which is caused by cosmetic hair treatments, the overall structure of these hair follicles becomes compromised.

How Can I Tell If I Am Losing Too Much Hair?

The "pull test" is one of the easiest ways to determine whether you are losing too much hair. Take a small patch of dry, clean hair, running your fingers through until you are just about to reach the end of the strands. Once you are close to the end, tug gently.

If more than 3 hairs detach from your scalp, you might be experiencing anagen or telogen effluvium. As a guide, you should not lose more than 10 hairs for every 100 strands that you tug on. If you are losing more, it is advisable to consult with a doctor to find the cause.

When Should I See a Doctor?

Schedule an appointment with a doctor if you are worried about the amount of hair that you lose every day. If you have started to notice bald or patchy spots across your scalp, the hair on the top of your scalp is gradually thinning out, or you have started to lose hair all over your body, it could be an indication of underlying health conditions.

Your doctor should be able to determine whether the hair that you are losing is normal or whether there is an underlying issue.

How Does Hair Loss Affect Men Vs Women?

Male Pattern Hair Thinning

Also known as androgenetic alopecia, male pattern hair thinning is a very common hair loss type in men. The U.S. NLM (National Library of Medicine), states that over 50% of men that reach the age of 50 and older will be impacted by this condition to a certain extent.

What Causes Androgenetic Alopecia?

Genetics is one of the main causes of male pattern baldness, or when your family history is linked to baldness. Studies have discovered that Androgenetic alopecia is linked to androgens which are male sex hormones. The androgens perform various functions which include the regulation of hair growth.

Every hair strand is going through the growth cycle. With Androgenetic alopecia, these growth cycles start weakening, which causes the hair follicles to shrink. This results in producing finer and shorter hair strands. Eventually, growth cycles for each hair strand will end, where new hair will no longer grow to replace it.

Hair Loss in Men

Male pattern hair thinning that is inherited typically will not have any side effects. However, in some cases, hair thinning can be linked to a more serious cause, including certain types of cancers, anabolic steroids, thyroid conditions, and medications. It is important to schedule an appointment with a doctor if you start losing hair after starting a course of a new medication or when you are experiencing any other type of health complaint.

Doctors typically use patterns of how you are losing hair to diagnose androgenetic alopecia. They might perform an exam and look into your medical history to eliminate certain conditions as a cause. This can include nutritional disorders or if you have ever experienced a fungal condition on your scalp.

A health condition could be what is causing hair loss or baldness when either pain, redness, a rash, hair breakage, patches of hair loss, or when the scalp starts peeling accompanies your hair loss. Blood tests or skin biopsies may become necessary to detect a disorder responsible for your hair loss.

Who Is Most at Risk?

Male pattern hair thinning or Androgenetic alopecia can start as early as the teenage years but occurs more commonly in adults where it starts to increase with age. Genetics also plays a significant role. Men that have a close relative such as a father or grandfather that has Androgenetic alopecia are usually at higher risks. This is even more prevalent when the relative was on your maternal side.

Hair Loss in Women

Around a third of adult women will experience alopecia (hair loss) at some stage in their lifetime. When it comes to postmenopausal women, up to two-thirds can experience bald spots or hair thinning. Losing hair as a woman has a more significant impact when compared to hair loss in men since it is not as "socially acceptable" for women. Alopecia often affects the emotional security and well-being of many women.

The primary hair loss type in women is very similar when compared to hair loss in men. It is called androgenetic alopecia, or female pattern hair loss. With men, the loss of hair usually starts just above the temple, where the hairline recedes to form the characteristic "M" shape.

The hair over the top part of the head will also start thinning out, which often progresses to sparseness in certain areas of the head. In a woman, androgenetic alopecia starts with a gradual thinning that occurs at the parting line. This is followed by an increase in hair loss that radiates from the crown. In women, the hairline will rarely recede, and it is not common for a woman to lose all their hair.

There are several potential reasons why women experience hair loss, including medications, emotional and physical stress, or a medical condition. If you start noticing hair loss that is unusual, it is advisable to see a dermatologist or health practitioner so that they can diagnose the exact cause to provide you with the appropriate treatment.

You can also ask your doctor to provide you with a referral if you would like to attend support groups or see a therapist if you need to address an emotional difficulty. Hair loss, especially in women, can be extremely frustrating and embarrassing, but over the last few years, there are more resources than ever to cope with these problems.

How To Naturally Prevent Hair Loss

Wash Your Hair Regularly with a Mild and Gentle Shampoo

Washing your hair regularly helps to prevent hair loss when you keep your scalp and hair clean. This also lowers the risks of infection or dandruff which could result in hair loss or breakage. At the same time, when your hair is clean it promotes a more voluminous look.


Vitamins are great for your well-being and health, as well as for your scalp and hair. Vitamin A, for example, encourages sebum production for your scalp, while Vitamin E promotes blood circulation to your scalp, which helps the hair follicles to remain productive.

Vitamin B also helps to maintain a vibrant and healthy color. Biotin is a popular marketing hair vitamin but all clinical trials conducted with biotin have not shown much success. We do not recommend wasting time with this vitamin and encourage supplementing your diet with curcumin, quercetin, iron, zinc and other more beneficial vitamins.

Include More Protein in Your Diet

Eating lean meats, soy, fish, or any other source of protein promotes healthy hair, which helps to curb or slow down hair loss.

Stay Hydrated

Your hair shafts are made up of 1/4 water, which is why you should be drinking at least 4 to 8 glasses of water every day to promote healthy hair growth.

Stay Away from Things That Are Bad for Your Hair

If you want healthy hair, it is important to know what you should be doing and what you should be avoiding. Never rub your hair with a towel. Rather allow your hair to dry naturally.

Limit Your Intake of Alcohol

If your hair is already falling out, lower your intake of alcoholic beverages since alcohol slows down hair growth. Eliminate or decrease your consumption of alcohol if you are struggling with hair loss.

Stop Smoking

Smoking cigarettes lowers the blood flow to your scalp, which can also lead to a decrease in your hair growth.


Research from previous years has discovered medical evidence that links hair loss with stress. One of the best ways to de-stress is by practicing meditation. Alternative therapies such as yoga or meditation reduce stress while restoring hormonal balance.

Physical Activity

Physical activity is very important to reduce stress levels, balance your hormonal levels, and curb hair fall.

Avoid Constant Drying and Heating

Try not to constantly subject your hair to drying and heating procedures. Heat will weaken the proteins in the hair shafts, while constant drying can result in fragility and weakness which also causes hair fall.
