How often should we wash our hair?

It is one of the most frequently asked questions in hair care, yet there is no universal answer. The ideal washing frequency depends on each person's hair type and scalp type.

The myth of a one-size-fits-all frequency

It is a myth to believe that one answer or frequency suits everyone. Some people hear that they should space out washes as much as possible, while others are told to wash their hair every day—but none of these rules apply universally. The right pace is determined by the actual needs of the scalp and the nature of the hair, not by a general trend.

Wash as soon as your hair is dirty

The basic rule is simple: it is important to wash your hair as soon as it is dirty, without allowing sebum to build up on the scalp. Delaying washing beyond that point only makes the situation worse, without any real benefit to hair health.

The case of an oily scalp

For an oily scalp, it is important to wash your hair frequently. The principle is the same as for facial skin: you would never recommend that a person with oily skin only wash their face once a week. The same reasoning applies to the scalp—spacing out washes only causes excess sebum to build up, without reducing the natural production of oil.

The case of curly or coily hair

Conversely, curly or coily hair does not need to be washed as frequently. Thanks to its spiral shape, the sebum produced by the scalp does not reach the lengths as easily. This type of hair can therefore space out washes without risking the buildup of sebum that would affect an oily scalp or straighter hair.

A minimum frequency to follow

Regardless of hair or scalp type, it is recommended to wash your hair at least once a week. Even for hair that is least prone to sebum buildup, a minimum weekly wash helps keep the scalp clean and healthy.
