"This product performs far better than Folligen spray which is marketed as a second generation product that is claimed to be better than Tricomin and supposedly has more copper peptide concentration. Whatever the content of each, Tricomin spray really works and Folligen spray does not. I also like Tricomin shampoo which noticably stimulates the scalp prior to spraying with Tricomen spray. I first used Tricomin spray and shampoo for about two months and it really worked. I switched to Folligen because of its cheeper price and claims of better performance, however, my hair loss increased dramatically. I switched back to Tricomin and, after only one bottle, my hair loss has decreased dramatically and new hair growth has begun. I also use Spectral DNC which is expensive and I'm not sure if it is working any better than generic Minoxidil which I have used for ten years. I lost hair when Folligen with Sprectral DNC. Now, I am bact to Tricomin along with Spectral DNC and I am noticing very substantial results after only one month of use. I would highly recommend Ticomin spray for anyone looking to stop hair loss even though I belive the price per bottle is entirely to much to demand."
