I have naturally curly hair, and I feel that Revivogen shampoo and conditioner do thicken my hair up pretty nicely. These products may also help out a bit with irritation, though in my experience, not as much as Nizoral. If you are using topical hairloss treatments, like Revivogen or spironolactone, then the menthol used in these products could be beneficial for helping with penetration. Overall, I love both the Revivogen shampoo and conditioner. I ended up liking the conditioner more than I expected, and I had to chose one or the other, I'd probably use the conditioner.
I have been using the American Crew Copper Peptide shampoo and conditioner for dry hair. I really like the conditioner but I may give this stuff a go after these bottles run out.
Ive been using a combo of revivogen and cu peptides (American Crew) and have to say I have seen a considerable reduction in numbers of hairs shedding and also have started to see some regrowth on my hairline - its only been 6 weeks so I hope im not just imagining things - but it seems pretty real to me
