Got it! The “how often to wash your hair” question actually depends on hair type, scalp health, and lifestyle, and dermatologists have specific recommendations rather than a one-size-fits-all answer. Here’s the breakdown:
1. Normal Hair & Scalp
- Recommendation: Every 2–3 days
- Normal hair doesn’t get very oily quickly, so washing too often can strip natural oils.
2. Oily Hair or Scalp
- Recommendation: Daily or every other day
- Oil builds up faster, so frequent washing helps prevent greasiness and clogged follicles.
3. Dry or Curly Hair
- Recommendation: 1–2 times per week
- Curly hair tends to be drier because natural oils have trouble traveling down the hair shaft. Overwashing can make it brittle.
4. Very Active Lifestyle
- Recommendation: Wash after heavy sweating or workouts, even if your hair is usually dry.
- Sweat can irritate the scalp and cause odor.
5. Color-Treated or Chemically Treated Hair
- Recommendation: 1–3 times per week
- Overwashing can fade color or weaken treated hair.
Extra Tips from Dermatologists
- Use gentle, sulfate-free shampoos to avoid stripping oils.
- Condition regularly, focusing on ends rather than scalp if hair is oily.
- Adjust frequency seasonally—scalp can get oilier in summer, drier in winter.
💡 Bottom line: There isn’t a “perfect” number for everyone. Listen to your scalp: if it feels greasy, itchy, or flaky, it’s time to wash. If it feels fine, washing less often is usually better.
