To be honest, I have always felt that shampoos (other than nizoral) aimed at regrowing hair are a waste of money. I'm sure others would disagree with me and I would be surprised if anyone could show results with just using a regrowth shampoo alone. I would stick with the nizoral and possibly increase to monday wednesday friday if your scalp can handle it. Personally, I use all natural shampoos the other days of the week as I feel like the chemicals in most shampoos probably do more harm than good to your follicles. I used some stuff called "african black soap" from whole foods for most of my regimen and most recently switched over to the whole foods 365 peppermint store brand. Both are around 10-12 bucks for a big bottle and last me around 2 months. Just be sure to wash thoroughly to clean the scalp of any dht-containing sebum and rest assured that nizoral 2-3x per week will do its part keeping your scalp nice and clean. If you can tolerate it, a dht blocker like finasteride would be your best weapon to add to your regimen.
