Bom dia, Klaus. We have the same sh*t here... Finasteride, Minoxidil 5%, and the cetoconazol shampoo (here it is called Nizoral) but only at 1%, we need a prescription for the 2% stuff. We get our salycilyc acid in a shampoo called T-Sal.
I am not sure what Avicis is (17 alfaestradiol, anyone?), and I am not sure how to translate the piritinato de zinco.
Some stuff that we use here in addition to what you use are Spirolactonone, which is a drug that transsexuals take internally, but if you apply it as a lotion to the hair it helps fight DHT without the feminine side-effects to the rest of the body. Some of us here also like using Copper Peptide solutions to calm irritation and improve hair quality.
On the whole, the stuff you have to take seems to be pretty much the same sh*t we got here in the States, except we don't have the cachaca and pretty girls like you got down there, bud. Boa sorte.
