What Hormones Affect Hair Loss

What Are The Cycles Of Hair Growth

Hair Loss, Menstrual Cycle and Hormones

Hair goes through three cycles:

  • The anagen phase can last from two years to eight years. This phase generally refers to about 85% to 90% of the hair on your head.
  • The catagen phase is the time that hair follicles shrink and takes about two to three weeks.
  • The telogen phase takes about two to four months. At the end of this phase, the hair falls out.

Your shorter hairs like eyelashes, arm and leg hair and eyebrows have a short anagen phase about one month. Your scalp hair can last up to six years or even longer.

What Causes Hair Loss In Women

When most people hear the words hair loss, they think of balding men. However, hair loss can also be a significant problem for women. Female hair loss can occur for several reasons, from a genetic sensitivity to certain androgenic hormones to reactive factors.

Weve listed the most common causes of female hair loss below, as well as the specific ways in which each cause can affect your hairline.

Why Dht Affects People Differently

Your proclivity to hair loss is genetic, meaning that its passed down in your family.

For example, if youre male and your father experiences male pattern balding, its likely that youll show a similar balding pattern as you age. If youre already inclined to male pattern baldness, the follicle-shrinking effect of DHT tends to be more pronounced.

The size and shape of your head may also contribute to how quickly DHT shrinks your follicles.

What Are The Hormones That Cause Hair Loss

Hormones are the chemical messengers in our body which are a part of endocrine system that control our body systems. In a way, hormones help our body to sustain and thus any imbalance in their constitution results into a number of problems. There are certain hormones which affect our hair nourishment and health, thus causing hair loss

Testosterone This is a male hormone and excess production of it can cause androgenetic alopecia in both men and women. With excess of testosterone being produced in the body, it gets highly reactive to dihydrotestosterone, or DHT, which are by-products of testosterone in the body. With the rise of testosterone in the body, the DHT levels rise as well and this causes an increase in the rate of hair loss.

Thyroxin Thyroid gland releases thyroxin hormone, a component that regulates the metabolism of the body and maintains its energy in order to support smooth functioning. But, if there is an imbalance in the amount of thyroxin produced, then it results in conditions known as hypothyroidism and hyperthyroidism , which in turn is capable of causing many irregularities, including weight gain and hair loss.

Insulin This is a hormone that is produced in the pancreas and it helps the body in regulating the blood sugar levels. Insulin is capable of affecting several body processes like fat storage and hair loss. Studies indicate that people with insulin resistance are probable candidates for androgenic alopecia , or female pattern baldness.

Can Menopause Cause Hair Loss

4 Ways Your Hormones Affect Hair Loss

Menopause is an inevitable part of life for women. Women naturally produce a large amount of the estrogen hormone as well as a small amount of testosterone hormone. However, as their estrogen levels decrease during and after menopause, their testosterone increases. As a result, the testosterone within their hair follicles is converted into a strong hormone dihydrotestosterone which can inactivate hair follicles, thus leading to hair loss.

Each cause can have different effects, some of which are permanent and some that are temporary.

Thyroxine & Triiodothyronine T4 & T3 From Thyroid

The overproduction or underproduction of hormones thyroxine & triiodothyronine can result in:

  • Hypothyroidism
  • Hyperthyroidism

These conditions can result in thyroid hair loss in females. According to Office on Womens Health , women are at a greater risk of developing thyroid disease. The risk is higher after they get pregnant or after menopause. This may indicate that theres some link between the female hormones and thyroid diseases which makes them more susceptible to them.

As part of the endocrine system, the thyroid produces hormones designed to regulate the regeneration and growth of cells and cellular energy. For this reason, hair depends on the thyroid to grow.

If you have thyroid disease, you can lose hair either due to the shock to the body due to the hormonal imbalance itself. However, another reason may be autoimmune conditions, which can result in thyroid diseases. This kind of immune response by the body can result in alopecia areata, which is the most common non-hormonal hair loss.

  • What is the normal hair care routine? Certain hair care practices can have a tremendous impact on the loss of hair health.

With proper evaluation and appropriate testing for hormonal imbalances or nutritional deficiencies, help is on the way!

Myths: Virility And Hair Loss

7 Effective Ways To Treat Hair Loss Due To Hormonal Imbalance #haircare ...

There are a lot of myths out there about balding men. One of them is that men with MPB are more virile and have higher levels of testosterone. This isnt necessarily the case. Men with MPB may actually have lower circulating levels of testosterone but higher levels of the enzyme that converts testosterone to DHT. Alternately, you may simply have genes that give you hair follicles that are highly sensitive to testosterone or DHT.

Women may also experience hair loss due to androgenetic alopecia. Although women have much lower levels of testosterone than men do, there is enough to potentially cause androgenetic hair loss.

Women experience a different pattern of hair loss. Thinning occurs over the top of the scalp in a Christmas tree pattern, but the front hairline doesnt recede. Female pattern hair loss is also due to the actions of DHT on hair follicles.

Everything You Need To Know About Hair Loss In Menopause And Perimenopause And How To Turn It Around

If the sight of hair in your shower drain or on your hair brush is causing you anxiety . you are not alone.

For most women, hair is an expression of our style, our personality, and our image. When our hair looks good, we feel good. Midlife hair loss is more than just a never ending bad hair day and can be very distressing. If we lose a lot of hair, we may feel less attractive, less feminine, less in control, and that can affect our self-esteem.

I get asked all the time if hormonal hair loss can be reversed. The answer is yes! Fortunately, unlike genetic hair loss, most hair loss caused by hormonal imbalances is reversible.

In fact, back in my 20s when I was diagnosed with primary ovarian failure I had all the classic symptoms of menopause, including hair loss I would often clog shower drains at my apartment since so much hair was going down it. My dad had to buy me a special drain cover because he was getting tired of coming over all of the time to deal with my plugged up drain! I went through a phase where I would dread washing my hair, because I didnt want any more to fall out. It was hard for me, especially at such a young age. The good news is that once I restored my hormones to healthy levels, my hair grew back and thicker and fuller than ever. So, there is hope!

Medications And Health Changes

Sometimes the unexpected happens. Introducing a new medication, rapidly losing or gaining weight, or simply adjusting to a new routine can all cause extreme hormonal fluctuations. These changes inevitably affect hair loss when it comes to maintaining your beautiful curls.

Check in with your doctor regularly if you find yourself experiencing unexplained hair loss and be prepared to adjust or supplement medications as recommended. Many beauty lovers find it helpful to keep a diary or note sheet of changes to discuss with their doctor in terms of skincare woes and hair hassles. Oftentimes these concerns get pushed aside or minimized for fear of sounding silly. Rest assured, any small changes are worth bringing up, even if youre merely looking to find fewer hair clumps in the shower drain!

When introducing new habits like a fresh workout routine or a significant dietary change, do so slowly. Remember to be kind to your body. Rapid and sudden shifts wont give your hormones time to adjust and get on board with the new routine. This can lead to a spike or drop in blood sugar which contributes to diffuse hair loss and often undermines any fitness goals you may be aspiring to.

Cortisol and the Flight-or-Fight Response

One of the main triggers that tells the body to release cortisol is stress. This is known as the flight-or-fight response. Historically this happened when, for example, a tiger was chasing our ancestors. Today it can happen when you are already late for work and get stuck in traffic, when you fight with your spouse about chores, or when your in-laws are visiting. However, the difference is that when the cortisol levels were raised in our ancestors it led to physical action. The stress of today is normally not followed by flight or fight, which makes Cortisol levels build up in our bodies, and that can be damaging.
