Male Baldness Info

My son is a white 21 year old male. He has always had thick, very coarse curly hair. Now his hair is getting somewhat thinner. And I’ve especially started noticing this around his front hair line. Yes, it could be genetic, because my dad lost his hair at an early age. In my husband’s family, the men have thick, full hair well into their old age. (But I’ve heard baldness is passed down through the mother’s side). It could also be stress – - – he is in college and holding down a job, etc.
My question is, would the Dr. Miracle’s Nape & Temple Grow products work on my son or is it only for African-American hair problems (mostly for women)? Does anyone know of any men who have had success with these products?

I read some interesting statistics the other day; 40% of American Men experience male pattern baldness in their lives. So I thought, how come all presidential candidates always have hair?
Also, the average male height is like 5’9″, that means about half of men are UNDER that average. So why are all presidential candidates 6 ft tall?
And how come, in the nation with the highest obesity, 90% of our candidates are slim?
Are we choosing presidents based on LOOKS?? The smartest person out there might not fit the look, and maybe that’s why we keep electing duds. If we are that superficial, maybe we are getting the presidents that we deserve. What do you think?
