DHT is a male androgen hormone that causes follicles to shrink, resulting in a shorter life span and decrease hair production

If you’re a mother, you probably recall during pregnancy how full your hair was. Many women say that the times when they’re pregnant are the times when their hair looks its best. And then you undoubtedly remember the aftermath of those months of gorgeous hair. All the hair that should’ve fallen out little by little now comes out in huge amounts of hair loss in just a short period of time. This is called telogen effluvium. This occurs in 40 percent to 50 percent of women, and it’s due to the change in hormones during pregnancy. Thankfully, it’s only a temporary hair loss. (10)

The hormones that we speak about when it comes to hair loss are the group of hormones called androgens. The three types of androgen hormones are testosterone, androstenedione and dihydrotestosterone, more commonly known as DHT. All of us have heard of testosterone and probably associate it with the male “macho” hormone. In fact, both men’s and women’s bodies contain all three of these hormones in some amount, and their imbalance can contribute to hair loss in both sexes.

The cause of hair loss in men is due to the hair follicles’ sensitivity to DHT (5α-Dihydrotestosterone). DHT is a male androgen hormone that causes follicles to shrink, resulting in a shorter life span and decrease hair production. Normally after hairs fall out another hair starts to grow from this same follicle, but if DHT is high hair growth decreases. Male pattern baldness (androgenetic alopecia in men) follows a pattern of a receding hairline that progresses to an “M” shape and then continues to the familiar “U” shape.

An example of very commonly used and conventional topical treatment is minoxidil. One of the most well-known versions is Rogaine. Conventional hair growth products like Rogaine are available without a prescription and can be used by both men and women. Finasteride is an oral medication for hair loss in men only and requires a prescription. Both minoxidil and finasteride do not get to the root of hair loss and only work to regrow hair as long as you use these medications. Once you stop using them, the hair growth, if any, will stop.
