A comb for the hair including a body having a lengthwise axis (X). At least one first gap is defined between two teeth of a first pair of teeth, with this first gap having a first height. At least one second gap is defined between two teeth of a second pair of teeth, with this second gap having a second height lower than the first height. In a preferred form of the teeth defining the first and second gaps, only the teeth defining the second gap are arranged to hold a lock of hair between them. At least one of the teeth defining the second gap includes a projection extending into this second gap. In a preferred form, all of the teeth defining the first and second gaps are located on the same side of the body of the comb.
