# How Often You Should Actually Wash Your Hair
Most people wash their hair far more frequently than necessary, dermatologists say. The ideal washing schedule depends on your hair type, scalp condition, and lifestyle rather than following a rigid weekly routine.
Washing hair too often strips away natural oils that protect the scalp and keep strands healthy. Dr. Hadley King, a dermatologist in New York, explains that frequent washing disrupts the scalp's natural balance. This disruption can trigger the sebaceous glands to produce excess oil in response, creating a cycle where hair gets greasier faster.
For people with dry or textured hair, washing once or twice weekly works best. Those with oily scalps may need to wash every other day initially, but King notes that reducing frequency gradually allows the scalp to regulate itself over time. Most people with normal hair can maintain healthy strands by washing two to three times per week.
Factors beyond hair type matter too. Climate, exercise habits, and product use influence how often washing becomes necessary. Someone who exercises daily and sweats heavily may need more frequent washing than someone with a sedentary routine. Similarly, people who use styling products or live in humid environments may adjust their schedule accordingly.
The temperature of water matters equally. Hot water opens the hair cuticle and strips oils more aggressively than lukewarm water. King recommends using cooler water during the final rinse to seal the cuticle and lock in moisture.
When you do wash, focus shampoo on the scalp rather than the ends of your hair. The ends, being older hair, need more protection from natural oils. Conditioner should apply primarily to the mid-lengths and ends, not the scalp.
Finding your ideal washing frequency takes experimentation. Start by extending the time between washes by a day or two. Your scalp will likely feel oily
