In any shampoo commercial, while the voice-over explains all the actions of this or that hair soap, the images show hair covered in suds, ready to be rinsed.
Whatever the situation in which we use soap, for our body or even washing the dishes, we always look for the appearance of this famous foam as the guarantee of effective cleaning.
But what is it really?
This is false, respond Caroline Bufalini, Klorane studio hairdresser, and Denise Guillouet, care testing manager Professional Products Division at L'Oréal.

Not indispensable
The origin of this preconceived idea?
“The foam has a dispersing action, we compare it to washing,” according to Denise Guillouet.
If it makes the experience more pleasant, it is not essential because it does not make the product penetrate better.
The proof: low poo without sulfates, parabens or dyes, solid and homemade shampoos, which are all devoid of them, are popular with beautystas.
To compensate for the lack of foam and ensure that each strand is clean, be careful not to add any product.
The L'Oréal Paris expert warns us: it will be more difficult to remove and will make the hair greasy.
A small amount in the palm of your hand is enough.
As such, it is not always necessary to shampoo twice.
“Most products today are single application.
It will be useful to make two if a dry shampoo has been used before,” explains the Klorane expert.
