Hot, hot, hot! How to react? 
Hydrate yourself constantly, eat lightly and do not go out during the hottest hours.

It is also very important to refresh the skin and eliminate sweat from the hair with  DB - Dermopurifying  at least once a week.

For shampoo, if you have fine and normal hair use  B6 - Eudermic Volumizing Bath  and for frequent washing; if your hair is dry use  B5 - Eudermic Bath . 

Don't forget  N1 - Light Moisturizing and Nourishing Milk  necessary for thin hair and  N2 - Mask  if the hair is dry or treated.

Let's hold on and this winter, let's remember how nice it was to stay warm.
