Over the last twenty years I’ve lost about 50% of the hair on my head. I pretty much resigned myself to living without that hair.
I started taking 3,000 IU’s of liquid vitamin D3 (gelcaps - daily) last fall to protect against the flu over the winter. I don’t take any other vitamins or drugs and my life style hasn’t changed since last fall. After about three and a half months, I surprisingly noticed that my hair is growing back at a rather rapid rate.
I checked the internet to see if there could be any connection between vitamin D3 and hair regrowth. I found the following information on a Dermatology Journal;

It appears that the hair follicle needs a component within vitamin D3 to initiate the action that moves the follicle from the resting state to the growth state.
Not saying it will work for everyone else, but it’s working for me.
