Abstract
A device for applying a fluid product to hair. The device includes a product reservoir, and a comb having at least two groups of teeth. The two groups of teeth each include at least two teeth, and the distance between the two groups of teeth is greater than the distance between at least two adjacent teeth in each group of teeth. In addition each group of teeth is supplied with product from at least one product exit opening communicating with the interior of the reservoir. The space between the two groups of teeth is substantially free of teeth or has projections whose average length is smaller than the average length of the teeth in the groups of teeth.
