Can too much progesterone cause hair loss?
Exactly what is the relationship between progesterone and 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 excess progesterone causes 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.
In this post, we shall take a look at and address the question of whether too much progesterone can 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?
High Testosterone And Hair Loss
You might also be asking the question: Does high testosterone cause hair loss?
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
Progesterone And Hair Loss
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 the 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 a special affinity for estrogen. So, if there is a 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, the estrogen level returns to normal, and the situation improves.
