Hopewas is correct that American Crew doesn't work well as a growth stimulant or thickening the hair shaft. It is way to weak for that
American Crew Cu-peptide solution is an excellent growth stimulator, and will double the rate of hair growth. American Crew has said that the Cu peptide conc. is comparable to that of Tricomin. None of the Cu peptide products are going to grow hair like 5% minoxidil, but they have other properties that are just as important to treating male pattern baldness.
Tricomin, folligen and American Crew work about the same:
1) increase rate of hair growth
2) best for inflammation-major part of male pattern baldness mechanism
3) works as well as 2% for increasing hair count and diameter
4) powerful anti-oxidant, protects the follicle from aging
5) brings optimal health to scalp tissues so hair follicles can thrive
6) may inhibit dht to some extent (according to Dr. Pickart who invented tricomin)
Obviously, Cu peptides need to be used with a proven 5ar inhibitor or androgen receptor blocker or both in order to fully treat male pattern baldness. I also use minoxidil 5% 1ml/day.
the spray made my hair look really thin
i thought the shampoo dried out my hair somewhat, but not the revitalizing spray. I use a hydrating shampoo and rinse with cold water if I'm going out.
