Is the ‘co-wash’ (washing the hair only with conditioner) effective for taking care of the hair in summer?

The technique of washing hair only with conditioner has become one of the most repeated tips on social media for taking care of your hair in the summer. But what do the experts think of him?

A few seasons ago, the technique of ‘co-washing’that’s to say, wash the horse only with conditioner, without shampoo, it has become one of the most popular methods to keep hair at bay in summer, especially if curly, and to “recover” it after long exposure to the sun and bathing in the sea and pool . Proponents have claimed that when used “occasionally” it cleans out unwanted oil while maintaining the essential moisture hair needs, while fighting the “frizz” effect.

However, is it really effective co-wash? According to data provided by Primor, which gathered expert opinions, not as much as some supporters on social media claim.

According to the Spanish Academy of Dermatology and Vereology (EDV), the the hair must be washed with shampoo, since it is the only product that ensures hair hygiene. Failure to do so can cause oil and dirt to build up on the scalp, making it look dirty and encouraging microorganisms and infections.

Other experts wonder about its function, since, as L’Oréal explains, “washing your hair only with conditioner makes no sense, since it is a product that has no was not created for this, but to nourish and bring softness to our mane”.

The solution? Use gentle shampoos which do not contain “harmful” substances, such as sulfate-free, silicone-free and paraben-free shampoos. hygienic products, but organic and natural, who take care of your hair from root to tip and who provide special care for the scalp.

As for conditioners, they recommend those that do not contain silicone because, although this substance provides extra shine, it does not dissolve in water and is very difficult to remove.
