I think I notice improvement in those pics. Nice work.
I've been on finasteride for just over 19 months and I've used Nizoral on and off. However, I cut my hair medium-short (from quite long) for the first time in ages and have started using Nizoral again. It really does make the hair look healthy and quite thick. It does give it a "fluffy" quality on the day you've used nizoral, but a bit of wax or hair clay sorts that out.
finasteride has maintained at worst, and thickened my hair at best (if it's not just the shampoo doing it) so I'm hoping that being more consistant with nizoral will give it a push.
