Hair loss has probably been happening very slowly since 30, but at 50, you start to notice. Bright overhead lights become your enemy. Hair goes through three stages of its life cycle. The first phase is called the antigen phase, and that's where the hair is still growing.

Interestingly, the antigen phase for the hair on your head is up to eight years, which is why you can grow your hair so long, while the antigen phase of an eyebrow is just a couple months.

As a comic, I have to say I'm very impressed. That might have been the first antigen phase joke in history. Phase two is called the catagen phase. This is where the hair is growing dormant and is dying from the inside out.

We should be celebrating that. Okay. Phase three is called the telogen phase. The hair pinches off and dies. Some hairs can reenter the life cycle. Others can't. Scientists now understand that it's hormones that drive these phases. Hormones are the drivers and the brakes on these processes. Hormones determine if you're a shag rug or a hardwood floor.

I'm getting way outside of my pay grade here, but... dihydrotestosterone, or DHT, which comes from testosterone, is a hormone. And I'm totally oversimplifying here, but DHT can send your hair into the telogen phase, and that's bad.

Well, women, by the way, also have testosterone. In fact, I learned that women have more testosterone than estrogen, but they have more estrogen than men. But testosterone, that's for everybody.

And you're asking the wrong guy because, again, this is way past my pay grade, but I did actually ask the same question. And the answer I got was that it's the conversion of testosterone to DHT. As men age, they have more DHT, which causes hair loss. The other thing that causes hair loss is decreased blood flow to the scalp. A healthy blood flow replenishes nutrients and oxygen.

Understanding these mechanisms built the entire hair growth industry.
