It prevents the color from running
Often the color loses its intensity over the weeks and shampoos. On the one hand, it fades by oxidizing due to exposure to UV rays, on the other it escapes through the scales of the hair which open on contact with too hot water. To avoid this, the mask may contain antioxidants, natural or synthetic (tocopherol, vitamin E, fruit extracts…). It also prevents the color from spinning by closing the scales well thanks to a slightly acidic pH (citric acid, vinegar, lemon extract, etc.).
It makes hair shine
colored hair are beautiful if the light reflects well. For this, many hair products use silicones that smooth and leave a shiny film. The natural method consists in neutralizing the limestone of the water which, by depositing on the hair, makes it dull, dry and damaged. To do this, the mask must contain acidic extracts, such as citric acid or lemon extract.
It repairs the fiber
Sensitized by colorings, but also by the environment (pollution, UV rays…), the hair can be damaged. If the hair fiber is affected, not only the hair becomes brittle, but they let the color escape more. To recompose the integrity of the fibre, the masks incorporate active ingredients which make it up such as keratin and ceramides, or which have a fortifying role such as panthenol (provitamin B5), rice or silk proteins.
It nourishes the lengths
Colored hair is often dried out. And all the more so if they are long and/or curly, curly. The mask is the essential product to nourish and replenish them, with mainly vegetable oils: coconut, olive, argan and shea butter, rich in essential fatty acids.
Which one to choose ?
