Washing and conditioning

There is no single right number of washes a week. The right routine keeps your scalp comfortable and clean while leaving the lengths soft rather than stripped.

How often should you wash?

Let your scalp guide you. As a rough starting point:

Wash more often if you exercise a lot, wear hats or helmets, or your scalp gets itchy or flaky when you leave it longer. Training your hair to "need" fewer washes by skipping them works for some people and not others; if your scalp becomes sore or spotty, go back to washing more often.

Choosing a shampoo

Shampoo is for the scalp. Look at what you want it to do rather than the marketing:

Conditioner: lengths and ends, not roots

Conditioner smooths the cuticle, reduces tangles and makes hair easier to comb without snapping it. Apply it from about the middle of the hair to the ends, where hair is oldest and driest. Most people don't need it on the scalp, where it can make fine hair flat and greasy.

A simple wash routine

  1. Detangle gently before you get in the shower if your hair knots easily.
  2. Wet your hair thoroughly with warm, not hot, water.
  3. Shampoo with your fingertips, not your nails, concentrating on the scalp. Let the lather run through the lengths as you rinse.
  4. Squeeze excess water out, then apply conditioner to the mid-lengths and ends. Leave it on for a few minutes.
  5. Detangle with a wide-tooth comb while the conditioner is in, starting at the ends and working upwards.
  6. Rinse, then squeeze water out with a soft towel or cotton T-shirt. Avoid rubbing, which roughens the cuticle and causes frizz.
