I'm using scalp scrubs for years now. I do not enjoy AHA ones since I got dyed hair. My favourite was The Body Shop Green Tea Hair Scrub but it's sold out and not sure if it's coming back. I started to use Christophe Robin Purifying Cleansing Purifying Scrub with Sea Salt and it works as well as TBS. Yes, sea salt sounds bad, but my hairdresser didn't say that anything is bad about my scalp. I got problems with my scalp clogging and leaving too much oil on the scalp and hair, this way I can clean hair follicles well :)
