Can Too Much Progesterone Cause Hair Loss

Can too much progesterone cause hair loss?

This is one of the questions we have been bombarded with in the past. Interestingly, people who ask this question have established in their hearts or have heard it somewhere that a high level of progesterone contributes to hair loss.

So, they sum up the courage to ask us just to know if what they’ve heard is correct. Hope you are not one of those who are left in the web of confusion as to whether or not the information is accurate?

Well, if you are, you are going to get the right information here. Just wait to see how right or wrong you may be.

In this post, we shall take a look at and address the question; can too much progesterone cause hair loss?

To start with, let’s consider what hair loss is. We cannot be handling a condition we know little or nothing about. That is why it is crucial first to understand what hair loss is all about before going ahead.

What is Hair Loss?

I understand that we’ve covered a lot about this topic here in the past, but for the sake of clarity, we’ll touch it again.

Hair loss otherwise referred to as “Alopecia” is a medical condition in which there is a loss of hair from the head or other body parts. Hair loss occurs naturally as part of the processes that the human hair undergoes. If you lose some hairs, the body grows new ones to replace the ones that were lost.

However, permanent hair loss takes place when the body is unable to replace the hair that is lost or when it cannot reverse hair loss, thereby leading to thinning of hair or balding in the head or other parts of the body containing hairs.

Unusual hair loss can result from several causes including medication, stress, sleeping disorder and hormonal imbalance such as a high level of estrogen.

Testosterone As Part Of The Culprit

According to Lara Briden, testosterone, insulin resistance, and PCOS are responsible for hair loss. The post reveals that the aforementioned can adversely cause hair thinning as well as hair loss in men and even in women.

Furthermore, a study by the National Institutes of Health (NIH) shows that:

Hair loss comes from hair follicles shrinkage and the resulting impact of the growth cycle. A high level of free testosterone in the body leads to some of the hormones being converted by an enzyme (5-alpha-reductase) into Dihydrotestosterone (DHT).

DHT’s action combines with the sensitivity of the hair follicles to cause hair loss. However, it must be noted that testosterone or DHT alone does not cause hair loss. There is a genetic link attached.

Askmen concluded by saying that only those who are genetically predisposed to male pattern hair loss would develop hair loss whether there is an increase or reduction in testosterone levels.

Estrogen Encourages Hair Growth

Some persons have also tried to lay the blame for hair loss at the doorsteps of estrogen, but Hairsentinel explains the functions of estrogen to include the following:

  • Reduces body hair
  • Increases  the hair growth on the head
  • Decreases muscle mass
  • Regulates menstrual cycles
  • It promotes smooth skin, etc.

What Is Progesterone?

Progesterone is a sex hormone that is secreted by the female reproductive system. It is mostly secreted in the ovaries during the second week of the menstrual cycle. It plays a significant role in everyone’s health. It helps to regulate the female menstrual cycle and can also correct physiological changes associated with menstrual cycle.

Does Progesterone Cause Hair Loss?

Ordinarily, progesterone serves as a precursor in the production of other crucial hormones like cortisone and estrogen. Progesterone hinders an enzyme, 5-alpha reductase.

It equally stops the conversion of testosterone to dihydrotestosterone or DHT, which is biologically active metabolite found in the body. DHT is known to cause hair loss because of the role it plays in damaging hair follicles.

Progesterone is a natural blocker against androgen receptor. Its main work is to protect the hair follicle from the effects of testosterone. It is the hormone responsible for more hair growth in women during pregnancy.

In women, regular ovulation is believed to stimulate the secretion of more progesterone. But some conditions like PCOS, stress, and pills can reduce or prevent progesterone production. Stress can even make the body to convert progesterone into cortisol.

Estrogen Deficiency, A Possible Cause

Hair follicles have special affinity for estrogen. So, if there is lack of estrogen, the hair would most likely suffer some losses.

In women, there could be vaginal dryness and scanty light periods. They are said to be caused by some factors like an eating disorder, low body weight, low-carb diet, stress, smoking, and gluten intolerance. But when the underlying cause is corrected, estrogen level returns to normal, and the situation improves.

How Too Much Progesterone Causes Hair Loss

Too Much Progesterone Can Cause Hair Loss

Now, back to the question, can too much progesterone cause hair loss?

The best way to explain that correctly is that it can actually cause it. Here’s the explanation.

When you are treating estrogen or progesterone deficiency, you must use natural progesterone to correct the problem. However, it must be used with caution because excessive application of progesterone tends to lead to hair loss.

How does this happen? When the hair follicle is exposed to excessive progesterone, it shuts down and stops responding. You only need small doses of progesterone, thyroid hormone, and estrogen to take care of the problem.

However, one good way to solve the problem is to return to normal ovulation instead of depending on pills or other medications.

When you are tempted to add more to the quantity of hormones you are already taking, then you really need to reduce it at that point. If you are not sure what to do, you have to see the doctor for further directives.


Hair loss is mostly caused by testosterone, DDT, insulin resistance, and deficiencies of progesterone and estrogen. To get the problem corrected, find out and correct the primary cause.

Though progesterone is employed in the correction of hair loss, care must be taken while using it, as excessive use of the hormone has the power to cause more hair loss instead of correcting the problem.


  1. The problem is something that too few folks are speaking intelligently about. I’m very happy that I found this during my hunt for something concerning this.
