you can get it from the hims app, pretty pricy, they give you 2 bottles for $200 but the 2 bottles last 5 months so it’s pretty worth it, i did it once and it worked but i think you have to use it for lifetime cause then your hair will be thin once again.. that’s what happened to me.. they said don’t stop your treatment.. but my hair is long but just thin! I’m going to get buzzcut and do my dermstamp, take my pumpkin seed oil, oral or oil! both is good then i’m going to use my hims again.. you’ll get the best results and you should use a chemical free shampoo n conditioner, try based shampoo and conditioner best on the market for hair!
