Some of these are to be considered, as such, false and without scientific basis; others may be based on a degree of truth.
Let's see below which preconceptions are more difficult to dispel and which "grandmother's advice" can be considered valid.
that make a lot of foam, in general, contain SLES (Sodium Laurylether Sulphate), SLS (Sodium Lauryl Sulfate) and parabens. On the contrary, less foaming shampoos are more delicate and respect the scalp; while washing thoroughly, they are not aggressive.The sulphate agents act as surfactants, therefore they dissolve the grease and dirt to make it wash away from the water. In fact, they have an excellent foaming and detergent capacity but, for this very reason, they are aggressive on the skin and hair. As far as possible, therefore, the use of products containing SLES and SLS should be limited: in the long run, they can dehydrate the hair and alter the hydrolipidic film of the scalp.
Parabens, on the other hand, are chemicals used in cosmetology for their preservative power. Their long-term effects on skin health have been under fire and are yet to be definitively proven. In Italy, only a few companies have chosen to eliminate them from their products as a preventive measure. Pending more details on their effects, the use of shampoos containing them is not recommended especially for those with particularly delicate skin and children under 3 years of age.
