Shampoo

Use shampoo as often as necessary, but as infrequently as possible—find the right balance for your curls. If you tend to shampoo more often (for example, after exercising), focus mainly on the scalp and roots. This way, the roots will be cleaned and rid of the oil produced by the body, without over-drying the ends (the oldest hair).
In the shower, always finish with conditioner.
