I've been using the Act+Acre Salicylic Acid Scalp Exfoliator, and it's helped treat my hair really well. It gets rid of buildup and flaky skin well, making my hair feel clean and refreshed. The salicylic acid exfoliates without being too rough, and after using it regularly, I've noticed a big difference in how itchy and flaky my skin is. The dropper-style bottle makes it easy to use, and I like that it doesn't dry out my hair. It's a simple but effective way to keep your scalp healthy, and I can tell you that it's made my scalp healthier since I started doing it.
