-
Every 2 to 3 days
This routine maintains a healthy oil balance without stripping the scalp.
Best practices:
-
Alternate between regular shampoo and a mild or moisturizing one
-
Use conditioner mainly on mid-lengths and ends
-
Avoid excessive heat styling between washes
Dermatologists consider this range ideal for most people.
3. Dry or Sensitive Scalp: Every 3–7 Days
If you experience dryness, flaking, tightness, or irritation, washing too often may worsen the problem.
Signs of a dry scalp:
-
White flakes (not greasy)
-
Itchiness
-
Tight or uncomfortable feeling
-
Dull, brittle hair
Dermatologist recommendations:
-
Wash every 3 to 7 days
-
Use hydrating, fragrance-free shampoos
-
Avoid hot water—lukewarm is best
-
Incorporate scalp oils or treatments if needed
Skipping washes allows natural oils to nourish the scalp and hair.
4. Curly, Coily, or Textured Hair: Once a Week (or Less)
People with curly or coily hair often benefit from less frequent washing.
Why?
-
Curly hair struggles to distribute oil from the scalp to the ends
-
Over-washing leads to dryness and breakage
Dermatologist-approved routine:
-
Wash once every 5–7 days
-
Use sulfate-free or co-wash products
-
Deep condition regularly
-
Cleanse scalp gently without rough scrubbing
Many dermatologists emphasize scalp health over strict shampoo schedules for textured hair.
5. Fine Hair vs. Thick Hair: What’s the Difference?
Fine hair:
-
Shows oil faster
-
Often needs more frequent washing (every 1–2 days)
Thick hair:
-
Holds oil better
-
Can go longer between washes (every 3–5 days)
Hair density influences how visible oil buildup becomes—not necessarily how dirty your scalp is.
6. Active Lifestyle or Sweating: Adjust as Needed
If you exercise frequently or sweat heavily, you may need to wash more often—even if you have dry or curly hair.
Dermatologist advice:
-
Sweat itself isn’t dirty, but trapped sweat can irritate the scalp
-
Use gentle cleansers
-
If washing daily, rotate with mild shampoos or rinse-only days
Dry shampoo can help between washes, but it does not replace real cleansing.
7. Age and Hormones Affect Washing Frequency
Hormonal changes can significantly alter oil production.
Teenagers:
-
More oil due to puberty
-
Often need frequent washing
Adults:
-
Oil production stabilizes
-
Moderate washing works best
Older adults:
-
Reduced oil production
-
May benefit from washing less often
Dermatologists recommend reassessing your routine every few years.
Common Hair Washing Myths—Debunked
❌ “Training your hair to be less oily works”
✔ Oil production is controlled by hormones and genetics—not shampoo frequency.
❌ “Dry shampoo cleans your hair”

Oily scalp: every 1–2 days
-
Normal scalp: every 2–3 days
-
Dry or sensitive scalp: every 3–7 days
-
Curly or coily hair: once a week or less
The healthiest routine is the one that keeps your scalp comfortable, clean, and balanced.
Final Thoughts
Hair care isn’t about following rigid schedules—it’s about understanding your scalp’s needs. Dermatologists agree that washing your hair too often or too rarely can cause problems, but when done correctly, washing supports healthy hair growth and scalp function.
Instead of asking “How often should everyone wash their hair?”, the better question is:
“What does my scalp need?”
Listen to it—and adjust accordingly.
