it defianlty slowed it down to the point where it either doesnt happen or not noticably. it probly depends on the person. I would try only 200-250 for your first time since i know your causious.
its hard to say thou because hair will fall out when i shake my head but i cant tell if its just hair breaking off or hair coming out by the root. my hair is short and brittle from using minoxidill and nizerol every day.
i also have little tiny hairs from minoxidil i guess, not sure if i let my hair grow out if they would grow, they might be little bootleg hairs like arm hairs or they might just be strangled ones from dht.
i wish i knew about nizerol a long time ago. All this shit used to look so expensive to me so i never used it. But there is no reason not to buy nizerol, all newbies should just be told how cheap it is and to use it regardless if they care about there hair.
i wouldnt even mind shaving my head totally. I just wish it had the color of hair all over, like as if it was about to grow in full, i dont want a shiny head thats not even slightly hair colored.
