Hello, I'm 18 years old and unfortunately I have androgenetic alopecia. I'm currently a Norwood 1.5, maybe even lower, so this gives me some time to act before it's too late. As some people point out, sooner or later I will have to start with finasteride and I accept this, but my goal is gaining at least 2 years so I don't mess up with my growth which should end at age 20. So I bought Regaine and a ketoconazole Shampoo (Ketozolin 2%). Unfortunately as I read the package of Regaine, it says you shouldn't use it if you have blood pressure problems. Recently, I ' ve had the suspect of high blood pressure (yeah, it' s strange considering my age, I guess anxiety because of my hair contributed to it), so I temporary have to put Regaine aside. My doctor measured normal blood pressure, but at the pharmacy I got a clear high value. I can't explain myself how that's possible, anyway next Samsday I'm going to the hospital to be completely sure. So, I read some studies who confirmed that Ketoconazole is helpful against male baldness, so I applied some of it today for the first time. I was scarried when I saw that I was shedding a remarkable number of hair (given the fact that I massaged my scalp, it's not so worrying but still I shedded many more hairs than with a normal shampoo) and that my hair looked slightly thinner, it's not that bad but I can see my scalp more clearly than usual. Is this normal? I feel as if nobody can help me because this shampoo is not made to stop hair loss. I don't have dandruff, I have an oily scalp though.
