I just seen an advertisement for follicare...Does it really work, has anybody tried it?

I am posting because I am concerned for my dad, who stressed out about his hair all the time, it is thinning and receding he is 43, but one of his brothers also has thinning hair worse than him, and he is 40 and his other brother who is 45 doesnt have any signs at all.

My Grandma seems to think it is from wearing a hat, although I know a 21 year old who has less hair than a 30 year old that wears a hat everyday.


I beleieve it is genetics, but is there anything that can help with genetically losing hair?? ...Such as follicare??
