Regenera Activa - Stemcell Hair transplant

Hi,

I came across this today. Another stem cell treatment hitting the news. It seems to be like an effective treatment.

I don't know if my fear is unfounded, but not a fan of having a stem cell removed from me and then re-injected into me. I'm completely paranoid that it would turn cancerous or something else weird. I've read terrible things of stem cells going unstable and even turning into bones cells in the skin and making strange noises when people smile etc. Also having a scar in the back of my ear doesn't make me happy.

What are your thoughts on this? Is it worth the money? Will it really work? Is my fear unfounded?

Thanks.
