Hair Care Experts Advise Applying Oil 15–30 Minutes Before Washing

Hair‑care specialists say that applying oil to the scalp and hair about 15 to 30 minutes before bathing creates a protective layer that reduces water absorption and lessens shampoo chemicals' impact. This short‑time window helps preserve natural moisture, limit fungal growth on oily scalps, and avoid issues such as dandruff, itching, or increased hair shedding.

They caution that prolonged oil application may not suit everyone, especially those with naturally oily scalps, and recommend gentle massage while applying the oil. Overall hair health also depends on balanced diet, adequate sleep, stress reduction, and proper hair‑care practices.
