We try to unravel them, but the knots are so hard to give up that it becomes painful. And once dry, they are rough, brittle and dull, even electric.

No doubt: our hair is dry.

The best solution to fix it? Turn to a hair mask, a particularly effective care to repair them.

Catherine Chauvin, director of the René Furterer Institute, explains how to choose and use this essential.

Step 1: Perform a hair diagnosis

Whatever our needs and the nature of our hair, Catherine Chauvin always recommends to meet an expert to make an accurate diagnosis of his scalp and use the masks and care adapted to his requests.

Indeed, one can very well have the dry hair, but the greasy scalp (or conversely).

Step 2: Repair the Hydrolipidic Film with a Dry Hair Mask

"Many women have dry hair, either naturally or because of the techniques inflicted on their hair (locks, discoloration, accidental use of straightener.) The hydrolipidic film of the hair is altered and it is necessary to restore this barrier by bringing water and nutrients ", explains our expert.

This is where the hair mask comes in: after shampooing, it is applied wick and small amount, then it is left for 10 minutes covering the hair with a hot towel before rinsing thoroughly.

It can also be left overnight - by choosing either light textures that are simply removed by brushing your hair in the morning, or a richer texture to rinse.

Catherine Chauvin recalls that there are also masks pre-shampoo that can be applied for a few minutes before washing hair.

Ingredients, we hit hard with keratin (if they are very dry with peeling scales) or oils of coconut, argan, olive, camellia, avocado, beeswax and shea butter.

Tip: if you have dry hair but fine, it is better to avoid the oil-based masks, which may "plumb" them.
