🧴 Here’s How Often You Should Wash Your Hair, According to a Dermatologist
There isn’t one universal rule — how often you should wash your hair depends on your scalp type, hair texture, lifestyle, and product use. Here’s what dermatologists generally recommend:
🧴 Oily Scalp
Wash: Every day or every other day
- Oil builds up quickly.
- Frequent washing helps prevent clogged follicles and dandruff.
- Use a gentle or balancing shampoo.
🌿 Normal Scalp
Wash: Every 2–3 days
- Maintains natural oils without buildup.
- Adjust if you exercise frequently.
🌵 Dry or Curly Hair
Wash: Every 3–7 days
- Curly and coily hair tends to be drier.
- Natural oils travel more slowly down textured hair.
- Overwashing can cause frizz and breakage.
🏋️ If You Work Out Frequently
- You may need to wash more often.
- Alternatively, rinse with water or use a mild shampoo.
- Dry shampoo can help between washes.
❄️ If You Have Dandruff or Scalp Conditions
- More frequent washing with medicated shampoo may be recommended.
- Ingredients like ketoconazole or zinc can help (under medical guidance).
🚫 Signs You’re Washing Too Often
- Dry, brittle strands
- Itchy scalp
- Excessive frizz
- Increased oil production (your scalp may overcompensate)
🟢 Signs You’re Not Washing Enough
- Greasy appearance
- Flaking
- Scalp odor
- Itching
Bottom Line
Most people do well washing their hair 2–4 times per week, but the right schedule depends on your scalp’s needs — not trends.
If you tell me your hair type (oily, curly, color-treated, fine, thick), I can suggest a personalized washing routine.
