In the event you simply can’t skip the shampoo, Dr. Idriss mentioned, go for a gentle method that has “sulfate-free” or “mild” claims on the label, and keep away from sizzling water and extreme scrubbing, each of which may irritate the scalp.
As for drying, Dr. Alam really useful air drying at any time when doable, “which is the least traumatic in your hair.”
