So, what is the most common cause of hair loss?

Well, if you guessed androgenic alopecia, you are correct. Now, what is androgenic alopecia?

Well, it's pattern hair loss. Now, in men, it's the receding hairline and also loss of hair on the

top of your head. Now, in women, it's a little bit different. It's a kind of a diffuse thinning of the

hair all over. Now, this is actually very, very common. It affects 50 to 80 percent of men,

and 25 to 50 percent of females at some point in their lives. Now, the way hair loss medication

works, there's a couple different mechanisms. One popular drug works by increasing oxygen,

nutrients, and nitric oxide to the scalp, which increases circulation. But most hair loss

medications work by inhibiting a certain enzyme. And that enzyme is called five alpha reductase.

Now, what does this enzyme do? Well, it allows testosterone to be converted to a much more

powerful form of testosterone called DHT. If you have too much DHT in your body,

what happens is you get a thickened dermis around the hair follicles. So, it's going to suffocate

the hair follicle. You get increased fibrosis, that's kind of like a scarring, which wraps around

the hair. And then you also get calcification around the hair follicles. So, that's what DHT

does to your hair. So, DHT is a type of antigen. What's ironic about antigen, in general,

is they normally increase body hair, but then not on the top of your scalp. They actually,

you get a loss of hair on the top of your scalp, which is pretty odd. Now, let me just explain

more about this enzyme. Five alpha reductase. Now, when someone experiences castration,

there's a 95% decrease in antigens. And what happens at the same time is they stop losing their

hair. They stop experiencing energetic alopecia. Another point I want to bring up is people who are
