How do health-care professionals diagnose an ingrown hair?

The diagnosis of ingrown hair is typically very straightforward and based on the skin appearance. In some cases, a small skin biopsy may be used to help the doctor confirm the diagnosis. Other times, a skin bacterial culture may be taken by a cotton-tip applicator to assist in determining an infectious cause. A few other medical conditions may look just like ingrown hairs and need to be examined more closely by a physician specializing in conditions of the skin called a dermatologist.

Does diet have anything to do with ingrown hairs?

Overall, diet does not seem to affect ingrown hairs.

What else could an ingrown hair look like?

Other medical conditions can mimic ingrown hairs. Some possible look-alike skin conditions include folliculitis, keratosis pilaris, acne, cyst, abscess (furuncle), milia (whiteheads), eczema, impetigo, atopic dermatitis, contact dermatitis, heat rash (miliaria), or dry skin (xerosis).

Less common mimickers include chickenpox, herpes, pustular psoriasis, molluscum contagiosum, viral warts, Fox-Fordyce disease, Graham-Little-Piccardi-Lasseur syndrome, pruritic papular eruption of HIV disease, and erythema toxicum neonatorum. Folliculitis of ingrown hairs may also resemble uncommon skin conditions like lichen spinulosus, pityriasis rubra pilaris, phrynoderma (vitamin A deficiency), ulerythema ophryogenes, ichthyosis vulgaris, eruptive vellus hair pseudofolliculitis barbae, erythromelanosis follicularis faciei et colli, keratosis follicularis (Darier disease), Kyrle disease, lichen nitidus, lichen spinulosus, perforating folliculitis, and trichostasis spinulosa.
