I would assume biotin and tyrosine to be main players here ... and the antimicrobial/antifungal components to be helpfull aswell.
Horsetail has a good amount of silicia i think (?) but idk if that is actually useable like that topically.
I am also confused about the ammonia ... i thought its a potent neurotoxin ... maybe topically it is helpful as a antimicrobial?
the product also seems horribly expensive ... looking forward to your anecdotes.
