Females may lay up to 20-25 oval eggs on one hair follicle. Larvae (protonymph) and nymphs (deutonymph), with physical features similar to adults, are swept by sebaceous flow to mouth of follicle. First stage larvae emerge without legs. Larvae in later stages have six legs, as opposed to eight for adults. As immature mites grow, they become tightly packed. When mature, mites leave follicle, mate, and find new follicle in which to lay eggs. Entire life cycle spent on host: 14-18 days.
