Ingrown hair is a condition where the hair curls back or grows sideways into the skin. The ingrown hair condition is seen primarily among people having curly hairs.^[1] It may or may not be accompanied by an infection of the hair follicle (folliculitis) or "razor bumps" (pseudofolliculitis barbae), which vary in size. While ingrown hair most commonly appears in areas where the skin is shaved or waxed (beard, legs, pubic region), it can appear anywhere (e.g. eyelashes^[2]).

Anything which causes the hair to be broken off short with a sharp tip can cause ingrown hair. Shaving is the leading cause, followed by waxing and tight clothing. The embedded hair causes a localized inflammation (sometimes painful) response in the skin with prostanoid involvement. Sometimes ingrown hair occurs naturally without shaving, as too much dead skin or blocked pores can make hair grow sideways.

Symptoms include rash, itching skin, hair which remains in spite of shaving, and infection and pus collecting under skin. Treatments for ingrown hairs include putting a warm washcloth over the ingrown hair, shaving in a different direction, tweezing, exfoliating with facial scrubs, sponges, towels, or creams containing acids, and ibuprofen or other NSAIDs. Prophylactic treatments include twice daily topical application of diluted glycolic acid. Topical applications such as salicylic prepared solutions like Innovcool also aid dramatically in the treatment of the ingrown hair.^{[citation needed]}

Some people who chronically get ingrown hairs use laser treatment to completely prevent hair growth.^[3]
