Anti-dandruff/Clarifying Shampoo recos

Hello everyone! Anong gamit niyo pang clarify ng scalp niyo? Or dandruff shampoo for oily scalp? I have a very oily scalp and prone din minsan ng small bumps and pimples. I sometimes use Selsun blue (expensive huhu) but mejo dko gusto yung smell nya after a few days. I only wash my hair 2-3x a week since I have a 3C curly type of hair and nakaka damage talaga sa hair pag everyday ako nagbabasa.

Baka may ma reco kayo na effective and mas affordable den. Thank you!
