Lotion in spray format indicated to facilitate the removal of nits and soothe scalp irritation. It acts by smoothing the hair with its acid formula, facilitating the sliding of the nit along the entire length of the hair shaft by the action of the comb. In addition, the acidity and the particular composition combine to create a hostile environment to the establishment of lice, and provides an anti-irritation effect, leaving a pleasant and immediate sensation of freshness. Treatment for the first ten days before the use of the specific comb.
