Ingrown hairs and folliculitis: the back, the buttocks, the bikini line
Why it always comes back in the same places, and the four habits that change everything.
· Hajar Atila, registered nurse
An ingrown hair is a hair that has stayed under the skin: either the opening of the follicle has closed over under a layer of dead cells, or the hair, cut at an angle, grows back curving inwards. The skin treats that hair as a foreign body, and inflammation does the rest.
Why those areas
Bikini line, buttocks, nape, thighs, beard: these are the places where three factors add up — a thick curly hair, repeated shaving or hair removal, and constant friction. Skin with curly hair is more exposed, not through fragility but through geometry: a curved hair is more likely to dive back in.
Ingrown hair or folliculitis?
An ingrown hair is isolated, hard, sometimes with a hair visible in a loop under the skin. Folliculitis givesnumerous pustules, all alike, centred on the follicles, which often itch. The first is treated mechanically; the second is an infection or an overgrowth of yeast, and it calls for treatment.
The four habits that really change things
- Leave the skin alone.Extracting it yourself with non-sterile tweezers turns an ingrown hair into an abscess, then into a brown patch that lasts a year.
- Exfoliate gently and regularly, twice a week. It is the layer of dead cells that closes the opening: that is what you are aiming at, not the hair.
- Shave in the direction of the hair, on damp skin, with a new blade. A “closest possible” shave against the grain cuts the hair below the surface: it grows back shut in.
- Change after sport.Maceration under damp fabric does more for folliculitis than any product.
What we do at the practice
A targeted body treatment deep-cleanses the whole surface of the area, frees the hairs already caught without traumatising the skin, and calms the inflammation. On the buttocks and the back, it is also a question of access: these are areas that call for someone else's hand.
In the medium term, permanent laser hair removal, carried out at the practice, acts on the cause itself: fewer hairs, so fewer hairs working their way in.
When to see a doctor
A lesion that is hot, painful, growing, with a fever, or pustules spreading quickly: that is an infection and it is treated medically. Recurring painful nodules in the armpits, the groin or under the breasts suggest a chronic inflammatory disease that has its own treatment — and the earlier it is caught, the better it is controlled.
