I was watching an infomercial on ScalpMED. My friend has thinning hair as an elderly woman and is looking for what to try and that one has some pretty interesting before and after shots. Some people have gone from fairly bald to a fairly full head of hair in 5 months. I am not advertising for them, but I am saying it because if it works, they are saying it works by opening the channels for blood and oxygen and nutrition to flow to the hair roots.
They said that baldness is caused when a hormone called DHT constricts blood vessels that supply vital oxygen and nutrients to hair follicles, until eventually, the follicles can no longer grow hair and that their method works by keeping blood vessels in your scalp open and that having the blood vessels open allows oxygen and nutrients to flow into hair follicles, helping to revive the dying follicles.
The things that people are trying are all about increasing blood flow and oxygen to the scalp.
I know that there is a greedy scam industry, but things like infrared and PEMF are things I use for increasing blood flow and oxygen. I am not saying that it will work. I am saying that I am thinking that it might help even at slowing hair loss if it really is related to lack of blood flow.
