Pili multigemini, also known as "compound hairs," is a malformation characterized by the presence of bifurcated or multiple divided hair matrices and papillae, giving rise to the formation of multiple hair shafts within the individual follicles.
Pubic hair is terminal body hair that is found in the genital area of adolescent and adult humans. The hair is located on and around the sex organs and sometimes at the top of the inside of the thighs. In the pubic region around the pubis bone and the mons pubis that covers it, it is known as a pubic patch. Pubic hair is also found on the scrotum and base of the penile shaft in the male and on the vulva in the female.
Hair removal, also known as epilation or depilation, is the deliberate removal of body hair or head hair.
Shaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down—to the level of the skin or otherwise. Shaving is most commonly practiced by men to remove their facial hair and by women to remove their leg and underarm hair. A man is called clean-shaven if he has had his beard entirely removed.
Folliculitis is the infection and inflammation of one or more hair follicles. The condition may occur anywhere on hair-covered skin. The rash may appear as pimples that come to white tips on the face, chest, back, arms, legs, buttocks, or head.
Bikini waxing is the removal of pubic hair using a special wax, which can be hot or cold, that adheres to hairs and pulls them out when the wax is removed quickly from the skin, usually with a cloth strip. While the practice is mainly associated with women, male waxing has become a more common practice to remove men's pubic hair.
Laser hair removal is the process of hair removal by means of exposure to pulses of laser light that destroy the hair follicle. It had been performed experimentally for about twenty years before becoming commercially available in 1995 and 1996. One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998. Laser hair removal is widely practiced in clinics, and even in homes using devices designed and priced for consumer self-treatment. Many reviews of laser hair removal methods, safety, and efficacy have been published in the dermatology literature.
A carbuncle is a cluster of boils caused by bacterial infection, most commonly with Staphylococcus aureus or Streptococcus pyogenes. The presence of a carbuncle is a sign that the immune system is active and fighting the infection. The infection is contagious and may spread to other areas of the body, or other people; those living in the same residence may develop carbuncles at the same time. In the early 21st century, infection involving methicillin-resistant Staphylococcus aureus (MRSA) has become more common.
Pseudofolliculitis barbae (PFB) is a type of irritant folliculitis that commonly affects men who have curly or coarse facial hair. It occurs when hair curls back into the skin after shaving, causing inflammation, redness, and bumps. This can lead to ingrown hairs, scarring, and skin discoloration. PFB can be treated with various methods, including changing shaving habits, using topical creams or ointments, and undergoing laser hair removal. Prevention measures include proper shaving techniques, using sharp razors, and avoiding too close a shave.
Acne keloidalis nuchae (AKN), also known as "acne keloidalis", "dermatitis papillaris capillitii", "folliculitis keloidalis", "folliculitis keloidis nuchae", and "nuchal keloid acne", is a destructive scarring folliculitis that occurs almost exclusively on the occipital scalp of people of African descent, primarily men.
Perioral dermatitis, also known as periorificial dermatitis, is a common type of skin rash. Symptoms include multiple small (1–2 mm) bumps and blisters sometimes with background redness and scale, localized to the skin around the mouth and nostrils. Less commonly the eyes and genitalia may be involved. It can be persistent or recurring and resembles particularly rosacea and to some extent acne and allergic dermatitis. The term "dermatitis" is a misnomer because this is not an eczematous process.
Acne is acneiform eruptions. It is usually used as a synonym for acne vulgaris, but may also refer to:
Ingrown hair is a condition where a hair curls back or grows sideways into the skin. The condition is most prevalent among people who have coarse or curly hair. It may or may not be accompanied by an infection of the hair follicle (folliculitis) or "razor bumps", which vary in size. While ingrown hair most commonly appears in areas where the skin is shaved or waxed, it can appear anywhere. Anything that causes the hair to be broken off unevenly with a sharp tip can cause ingrown hairs. Ingrown hairs are also caused because of lack of natural exfoliation in the skin.
Acne miliaris necrotica is a severe form of folliculitis of typically the scalp. It presents as multiple fluid-filled bumps, sometimes occurring as solitary lesions that are usually very itchy. Shortly after appearing, the bumps burst and dry up. There may be scarring.
Body grooming is the act of maintaining a clean appearance. It is typically associated with hair.
Sycosis vulgaris is a cutaneous condition characterized by a chronic infection of the chin or bearded region. The irritation is caused by a deep infection of hair follicles, often by species of Staphylococcus or Propionibacterium bacteria. Asymptomatic or painful and tender erythematous papules and pustules may form around coarse hair in the beard or the back of the neck.
Prepubertal hypertrichosis, also known as childhood hypertrichosis, is a cutaneous condition characterized by increased hair growth, found in otherwise healthy infants and children. Prepubertal hypertrichosis is a cosmetic condition and does not affect any other health aspect. Individuals with this condition may suffer with low self esteem and mental health issues due to societal perceptions of what a "normal" appearance should be. The mechanism of prepubertal hypertrichosis is unclear, but causes may include genetics, systemic illnesses, or medications.
Shaving soap is a hard soap that is used to produce lather with a shaving brush. The lather it produces is used to coat the face during shaving, softening the hair in preparation for shaving.
Chafing is an irritation or superficial abrasion of skin caused by friction, moisture or irritating fabric. Prolonged rubbing on the skin may result in skin sting or burn, and development of a mild, red rash; and in severe cases may include swelling, bleeding, or crusting. It often results from body parts that rub against each other or against clothing. It commonly occurs on the inner thighs and buttocks, and nipples, groin, feet, and armpits can also chafe, although there it is less common. Severe chafing is known as friction burn.
