Good hair days start at the root: 13 best scalp treatments I swear by

Healthy-looking hair starts with healthy scalp skin, which is why finding the right scalp treatment can make a huge difference.As I reviewed options for the best scalp treatments, I kept coming back to a simple distinction from Karina Freedman, master esthetician and founder of KarinaNYC: “Hair is dead fiber.The scalp is living skin,” she explains.

Treating it means considering the skin’s barrier, microbiome, oil balance and overall condition.“The scalp has its own microbiome and its own barrier, and when either one is compromised, the hair shows it before you feel it,” she shares, after mentioning that “beautiful hair starts with healthy skin.”The best treatment depends on the problem.Dryness may need hydration and barrier support, while persistent itching or greasy, yellowish flakes can signal a different issue.
