Nizoral is quite a harsh shampoo, you’re absolutely right about that. It’s medicated and like any med, should not be overused. I only began using it about a month after my surgery as I have scalp issues. I only use it once a week. Personally, I would not exceed twice a week as spex has recommended on here for many years. I decided to stick to once a week bc I am trying to be more cautious.
it does have studies showing it is effective in addressing hair loss, but I think finasteride and minox will be doing a majority of the work.
