This depends on a variety of factors.
As a rule of thumb, the earlier you address hair loss, the better your chances of dramatic, more long-term results. Thinning hair indicates the process is underway. The follicles are shrinking, though they’re still alive.
So to answer this question, the earlier you use Profollica, the better your chances of regrowth for lost hair.
The good news is that Profollica has a very high satisfaction rate among men who want to protect and preserve their hair. Use it early, when you notice thinning hair, and stay with it for maximum results!
