My doctor gave me ketoconizole shampoo for dandruff and I also have pattern baldness. I have been using the shampoo for about 3 weeks.I have had shedding of hair (about 200-300)but since I have been using the shampoo shedding has increased a bit more(250-350)Also im noticing my hair is a lot thinner from the frontal area. Is this just an initial shed like minoxidol ? And does the shampoo help control pattern baldness as well ?
