OK I have being using this for over 2 months now and have noticed nothing, it may just be me but I could even say my hair looks worse. The product relies on arginine a nitric oxide precursor and aminexil. Arginine is good in some ways because it helps improve blood flow through vasodilation ( the nitric oxide) part, so it should help deliver more nutrients to the hair follicle but it would be minimal. Aminexil developed by a cosmetic not a pharmaceutical company from what I have read has little to no effect on thinning hair or hair loss. through aminexil hair loss is said to be caused through hardening of the hair follicle due to testosterone, partly true testosterone or to give it its correct name in this case dihydrotestosterone does not harden but over time shrinks the hair follicle making it thinner un till the hair is so thin you can't see it. also to note aminexil has never been approved by the FDA or MRHA for anything let alone thinning hair, despite what companies selling it may tell you in the many studies done on it. Best advise get a good cleansing shampoo and use minoxidil, which isn't as expensive as you may think. Its something I will be going back to very soon.
