Dermatologists previously explained to us the potential hair growth benefits of using a scalp scrub, a simple product addition that, while not normally a direct hair growth treatment, does help create more favorable conditions for optimal hair growth. "Soothing ingredients like aloe, tea tree, or peppermint help calm irritation and support a balanced scalp environment," board-certified dermatologist Dr. Divya Shokeen previously said. She also said she prefers sugar-based scrubs over large, coarse physical exfoliants because they dissolve easily with water, which helps prevent over-scrubbing, and provide controlled mechanical exfoliation without being too abrasive. Based on Shokeen's guidance, we selected the Mielle rosemary mint clarifying sugar scrub, the brand behind the ultra-viral hair-strengthening oil (see below) that many users claim has improved their hair growth. Just like the reviewer-beloved oil, the scalp scrub also contains rosemary oil, which can potentially accelerate hair growth by improving blood circulation in the scalp, thereby stimulating hair follicles, as well as nourishing hydrators like shea butter.
