Quick question about all these future treatments

[goldbondmafia]

I only know briefly about histogen, replicel and all these other treatments and I understand they will not be available to the public in the next year but are these treatments only going to work for people that are very bald?

In my case, I am 20 and still have relativley good hair minus slight thinning on the top and crown. Say for example I can halt my hair loss untill these new treatments are out and available...will they be able to help me in any way if rogaine for example stops working?

From what ive read it seems these companies are more for people who have already lost a great deal of hair and not for someone in my situation who has started thinning without any real hair loss issues.

Any ideas?
