The secret of Michel Mercier brushes lies in their unique geometric arrangement of bristles of varying heights and widths, which distribute the pressure exerted on the hair during brushing. The Michel Mercier set includes two detangling brushes, one for home use and one for travel. The full-size model is indispensable for daily brushing, while the compact travel version fits perfectly in your purse or toiletry bag. Ideal for both wet and dry hair.
