I swear I advise no one to use this product for hair loss as a topical or a standalone treatment. 99% of people using this treatment are usually high inhibition white chads that have minimal to no hair loss and are at NW0.5 instead of NW0. Every time I use this product my eyes start to flare up and I feel as if I am going to have a heart attack. This is coming from a guy that was not prone to feminization from high dose spironolactone or dutasteride. I have used 50mg, 150mg, 250mg, 500mg, and once a 1g application. My hair shedding in the shower barely changes after 250mg and higher. I still shed 85-115 hairs per shower (I shower everyday) while using this product. There has been times where I had to cover my heart with a pillow or lay against a wall while I cried that I did not get a heart attack. I will never use this product again and anyone who says it works is lying or doesn't have hair loss. I will wait until the first person on the internet posts improvement with this product, for me it did nothing but give sides.
