My male friend's scalp is so thin that it breaks my heart to see it, so I'm thinking of recommending a scalp stem cell injection program.

However, there are so many clinics and the prices vary so widely,

so I'm skeptical about whether the scalp stem cell injection program is actually effective in the first place, haha.

Given my friend's personality, I think he'll be disappointed if he just does a quick search and goes, so I desperately need information on a clinic that is really thorough and does a good job, haha.

If anyone has received treatment here and knows of a place you can trust and go to, please share it with me.
