How to Use Hair Conditioner Correctly: A Physician's Step-by-Step Guide
By Susan F. Lin, M.D. | Physician | Reviewed: June 2026
Quick Answer
Conditioner restores moisture to the hair shaft after cleansing. Apply to mid-lengths and ends only — not the scalp. Leave 2-3 minutes; rinse lukewarm. For damaged hair, deep-condition weekly with a mask. The MD Hair™ system approaches conditioning as part of sulfate-conscious daily care. Federally registered MD® trademark.
