Don’t Want To Lose Hair: How Often Is It Appropriate To Wash Your Hair?

Have you ever wondered why you seem to lose so much hair every time you wash it? Is it true that the more frequently you shampoo, the more hair you’ll lose? Or would washing less often help reduce hair fall?

Does Shampoo Frequency Really Matter?

Scientists have actually conducted research on the relationship between hair washing frequency and hair loss. The American medical journal Skin Appendage Disorders published a study exploring the impact of shampoo frequency on scalp and hair condition.

This two-week epidemiological study involved 1,500 participants aged 18–75 with no scalp conditions. Researchers divided them into five groups based on hair washing frequency: ≤1 time/week, 2 times/week, 3–4 times/week, 5–6 times/week, and 7 times/week (daily). The study concluded that:

• The more frequently they washed, the less scalp itchiness they experienced.
• The more frequently they washed, the better their scalp felt.
• Increased washing frequency did not significantly damage hair quality.
