The white gunk in hair follicles is usually a mix of sebum (natural oil), dead skin cells, and product residue, forming harmless plugs that can harden. However, it can also be white piedra, a fungal infection causing soft, gritty white nodules on hair shafts, or sometimes keratin plugs, which are keratinized skin cells. While most buildup is normal, excessive amounts might need exfoliation, but fungal infections or keratin plugs need specific care.
The "white gunk" you might notice in hair follicles is typically sebum, a natural oil produced by your sebaceous glands to protect and hydrate the skin and hair. Sebum, combined with dead skin cells and other debris, can build up around the hair follicle and harden, often looking like a white or yellowish gunk.
However, it is not the root, simply the protein bulb at the end of the hair that was closest to the root. In most cases, hair with a white bulb at the end of it will grow back — there is very likely a new anagen hair right behind it.
Folliculitis in children is inflammation of hair follicles, commonly caused by bacterial infections (like Staph aureus), fungi, or viruses, often triggered by sweaty or occluded skin, friction from tight clothes, or irritation from hot tubs/pools. Other causes include ingrown hairs (from shaving/tweezing), blocked follicles (thick creams/ointments), certain medications, or skin injuries, leading to red bumps, itching, or pus-filled pimples.
That sticky white material is almost always a mix of sebum (scalp oil), shed skin cells (dandruff), and hair-care product residue (shampoos, conditioners, styling products).
Piedra is the Spanish word for 'stone' and that is reflected in the appearance of this ailment. You'll find white, grey, or tan, pearly nodules surrounding your hair shaft. These are soft and loosely clump together on your hair. You'll find white Piedra on scalp hair, facial hair, and body hair.
How to get rid of scalp buildup: 6 expert-approved tips
Your hair follicles are surprisingly fragile and are prone to becoming infected and causing severe itchiness and discomfort. While folliculitis can be caused by outside elements not in your control, it can also result from not maintaining proper hygiene.
Folliculitis is often caused when hair follicles are infected with bacteria, commonly Staphylococcus aureus (staph). It may also be caused by viruses, fungi, parasites, medications or physical injury.
People may sometimes mistake psoriasis and folliculitis for other skin conditions, including:
Hair can regrow after being pulled from the root if the follicle remains intact, with signs including no scarring and a healthy bulb. Regrowth often occurs within two to three months, but repeated pulling or certain conditions can cause permanent follicle damage.
It may appear wispy or delicate in texture. Initial growth can be short, with new strands only a few centimeters long. The length may not be immediately noticeable. Some individuals experience soft and feathery new growth, particularly in areas that have been thinning.
Key takeaways: Key nutrients for healthy hair, skin, and nails include biotin, vitamin C, omega-3 fatty acids, and collagen. Most people can get these nutrients from their diet. But supplements may help if you have a deficiency, a restricted diet, or persistent hair or skin issues.
Over-moisturized hair looks limp, mushy, and lacks definition, with curls falling flat and feeling overly soft, stretchy (without bouncing back), and heavy, often appearing stringy or greasy, even feeling cool and damp for a long time after washing due to moisture overload and a lack of protein balance.
Folliculitis may be caused by the herpes simplex virus. This tends to be tender and resolves without treatment in around ten days. Severe recurrent attacks may be treated with aciclovir and other antiviral agents.
Lice eggs (nits).
Unless a child has many head lice, it's more common to see nits in the hair than live lice crawling on the scalp. Lice eggs hatch 1–2 weeks after they're laid. After hatching, the remaining shell looks white or clear and stays attached to the hair shaft.
Viral folliculitis is usually due to the herpes simplex virus or molluscum contagiosum and is relatively rare (though skin infection from these viruses is fairly common). When viral folliculitis occurs, it often occurs in people with immune system deficiency, such as HIV/AIDS.
Castor oil. As with tea tree oil, castor oil is effective at killing folliculitis-causing bacteria and also has the added benefit or relieving pain and itching where applied.
HIGH PERFORMANCE SHAMPOO: CLn Shampoo was physician-developed to effectively and thoroughly cleanse normal-to-oily hair and scalps prone to itching or flaking that accompanies folliculitis (irritated hair follicles), dermatitis and dandruff, including dandruff of the beard.
Haley Hernandez: Dr. Sherry Ingraham of Advanced Dermatology says there's a hard and fast expiration date for items in the shower. Bacteria can lead to conditions of acne, folliculitis, and other skin infections.
Hormonal Changes
These shifts can cause skin to produce more oil, clogging pores and encouraging bacteria to thrive. While folliculitis isn't primarily driven by hormones, hormonal imbalance can indirectly worsen both conditions by altering the skin's oil production, setting the stage for breakouts and inflammation.
Bacterial folliculitis (often Staph aureus) looks like itchy, pus-filled pimples (whiteheads/pustules) and can be worsened by shaving or hot tubs, while fungal folliculitis (Malassezia yeast) presents as uniform, small, red, itchy bumps (papules/pustules) on the chest/back, often unresponsive to acne antibiotics. Key differences are appearance (varied vs. uniform bumps) and cause (bacteria vs. yeast), with bacterial types needing antibiotics and fungal types requiring antifungals.
Look for a clarifying shampoo that contains salicylic acid, which helps to break down sebum plugs. Exfoliate your scalp: Just like exfoliating your skin helps remove dead skin cells and unclog pores, exfoliating your scalp can help to remove sebum plugs.
Dandruff is a common condition that causes flaking of the skin on the scalp producing small, loose, gray or white flakes. These flakes are typically larger than what is seen with dry scalp. Scalp associated with dandruff is typically itchy, oily and scaly but not inflamed.
Patches of greasy skin covered with flaky white or yellow scales or crust on the scalp, face, sides of the nose, eyebrows, ears, eyelids, chest, armpits, groin area or under the breasts. Rash that may look darker or lighter in people with brown or Black skin and redder in those with white skin.
