Not every two days, not every four days: a dermatologist reveals the ideal frequency for washing your hair

  • Use lukewarm water, not hot, to avoid drying out the scalp.
  • Massage gently with your fingertips, without scratching with your nails.
  • Apply conditioner only to the mid-lengths and ends, never to the roots.
  • If you wash frequently, add a nourishing mask once a week.

For best results, start by thoroughly wetting all your hair. Apply a small amount of shampoo to the scalp, massage, then rinse carefully before applying treatments to the lengths. Insufficient rinsing can leave residue and weigh the hair down.

A clean scalp is essential for both comfort and healthy-looking lengths. Waiting too long between washes can lead to a buildup of oil, sweat, and styling products, which makes the hair feel heavy.

Common myths to forget immediately

Some beliefs are hard to shake.

No, washing your hair frequently does not directly cause hair loss. The hairs you see falling out in the shower are usually at the end of their natural growth cycle.

No, your scalp does not “get used to” shampoo by producing more and more oil.

And no, washing less doesn’t automatically mean healthier hair.

As is often the case in beauty, it’s excess that creates problems: washing too often can weaken the hair, but spacing shampoos too far apart can cause discomfort.

The best frequency? The one that respects your scalp, your lifestyle… and allows you to follow a hair care routine that makes you feel good.
