Why is Menopause & Hair Loss Linked?
Female Pattern Hair Loss (FPHL) has long been associated with menopause. Researchers have investigated the role of hormones and hair loss; while there is lots of complexity as to why women loose scalp hair at a faster rate after menopause, there is a strong link to the drop in estrogen and progesterone that occurs around menopause.
There are lots of different hormone receptors in scalp hair follicles. Let’s group those hormones into two main categories – Estrogens and Androgens. Androgens are a group of hormones that can get labeled as “male” hormones, but that’s just because men have more of these hormones compared to women. Both men and women have all the hormones, but in different amounts.
What Role Does Estrogen Play?
Estrogens (and progesterone) have been shown to protect women’s scalp hair follicles. Androgens have been shown to weaken the hair follicles - resulting in hair loss. While estrogens levels decline after menopause, androgens decline at a much slower rate. This means that the androgens have more of an impact on the hair follicles than they used to.
Thus, estrogen and progesterone preserve and protect our scalp hair follicles, and androgens (particularly testosterone and DHT) weaken and reduce the growth of scalp hair follicles!
What About Androgens?
Where do these Androgens come from, where are they made in the body?
The ovaries make a little bit of testosterone but not much. Most androgen hormones start as either Androstenedione or as DHEA(S) in the adrenal glands and the hair follicles. These two hormones are converted to testosterone and another hormone called Dihydrotestosterone (DHT). These are more powerful androgens, especially DHT. Testosterone and DHT will inhibit growth of the hair follicle and reduce the hair’s attachment inside the follicle.
There are many things that influence the amounts of Androgens made by the body, but when someone has a lot of these factors then androgen levels will be higher than average. This can contribute to more hair loss.
So, What Does Contribute to Hair Loss?
A woman who has a number of these contributing factors will very likely have an increased chance that hair will start to fall out faster than it grows after menopause.
In Summary...
There is research which shows that both estrogen and progesterone work to strengthen the hair follicle and to promote hair growth. However, if someone has higher than usual androgens, estrogen and progesterone can only help so much. The reasons for hair loss are complicated, it is not just about changing hormones. We know food choices and lifestyle play a big role too. If hair loss continues, it’s a good idea to check in with your doctor to make sure there isn’t another factor affecting you.
