Scabies is an intensely itchy rash caused by a tiny mite that burrows into the top layer of skin. It spreads through prolonged skin-to-skin contact, it has nothing to do with cleanliness, and it clears with prescription treatment when everyone in the household is treated at the same time.
The same eight facts on every condition comparison.

Overview
Inflammation around hair follicles can produce itchy or sore bumps and pustules. Bacteria, yeast, irritation and occlusion are among the causes. This broad category includes Malassezia folliculitis; the cause determines treatment. Inflammation around hair follicles can produce itchy or sore bumps and pustules.

Classic scabies Itchy bumps and burrows with few mites.
Burrows between fingers A thin, winding track is visible in the finger web.
Crusted scabies Thick gray crusts with huge numbers of mites.
Nodular scabies Firm itchy lumps that can last for months.
Bacterial folliculitis Staph infection, the most common.
Hot-tub folliculitis From bacteria in poorly treated water.
Yeast folliculitis Uniform itchy bumps on chest and back.
Razor bumps (pseudofolliculitis) From hairs curling into skin.
Scabies mites burrow into the outermost skin and lay eggs there. The immune reaction to mites and their products causes an itchy rash; the itch does not mean the mites are burrowing deep into the body.
Infection, irritation or blockage can cause inflammation around a hair follicle. The response may produce a small tender bump or pustule around the follicular opening.
Scabies. Can affect people of any age after close contact with an affected person.
Folliculitis. Folliculitis Any age There is no single typical starting-age range. Bumps can follow shaving, friction, sweating or hot-tub exposure. Recurrent or unexplained episodes deserve an assessment of the cause.
Scabies is caused by a tiny mite that burrows into the top layer of skin. The intense itch is the body's allergic reaction to the mites and their eggs.
Folliculitis is inflammation of hair follicles, usually from bacteria, yeast or irritation.
Folliculitis describes a pattern of inflammation rather than one organism. Damaged or occluded follicles may become infected; shaving-related irritation can produce similar bumps without infection.
Most everyday folliculitis is not considered an inherited disorder. Skin conditions and individual susceptibility can influence risk.
Evidence labels come from each condition’s own treatment list.
Worth trying in the daytime, though scabies itch is only partly driven by histamine, so the effect is usually modest. They will not shorten the infestation or replace treatment. If the itch is stopping you sleeping, a sedating antihistamine at night is the more useful version of this.
Mild steroid cream helps the itch, but only after scabies has been diagnosed and treated. Used before that on an undiagnosed itchy rash it flattens the rash enough to make scabies much harder to recognize while the mites carry on spreading — sometimes called scabies incognito. If you have been using it, say so at your appointment.
A cool oatmeal soak settles the itch for a while during the weeks it takes the allergic reaction to fade. Keep the water cool rather than hot, because heat and hot showers reliably make scabies itch worse. It is comfort only, and it does nothing to the mites.
The home remedy asked about most often. It does kill mites in a dish, and small studies have looked at it, but there is no evidence it clears an infestation on a person. Applied neat to skin that is already scratched and inflamed it commonly stings and can cause a reaction of its own. Bleach and vinegar do not work either.
It does have some activity against bacteria and yeast in the laboratory, which is why it appears in so many folliculitis remedies. There are almost no proper trials of it in folliculitis, and undiluted tea tree oil is a common cause of allergic contact dermatitis, which produces an itchy rash on top of the one you were treating. A benzoyl peroxide or antifungal wash is the better use of the same shower.
A 4 to 10 percent wash lathered on in the shower and left for a minute before rinsing, for the bacterial kind on the thighs, buttocks, chest and back. It lowers the bacteria on the skin without an antibiotic, which is why it also works as a maintenance measure for people who keep getting crops. It bleaches towels, sheets and colored clothing, so use white ones.
An antiseptic wash used two or three times a week over the affected area, and a good option for someone whose bumps keep coming back in the same place. It lowers the bacterial load on the skin rather than treating an established infection. Keep it away from the eyes and ears, and stop if it stings or dries the skin, since damaged skin is the problem you started with.
The standard first move for the yeast kind: itchy, uniform bumps on the chest, back and shoulders, often worse after a course of antibiotics. Use the shampoo as a body wash a few times a week and leave it on for several minutes before rinsing. It does nothing for bacterial folliculitis or razor bumps, and yeast folliculitis tends to come back, so many people keep using it once a week.
It is the obvious thing to reach for because the bumps itch, and it is usually the wrong one. Steroid cream quietens the itch for a few days while the infection in the follicles carries on underneath, and the rash that comes back is often more widespread. It also changes how things look, which makes the diagnosis harder afterward. Cool compresses and a medicated wash are the safer starting point.
A leave-on 2 percent lotion or pad on the beard, neck or bikini line, where the problem is hairs curling back into the skin rather than an infection. It keeps the follicle opening clear so fewer hairs get trapped, and it is used between shaves rather than on raw skin. It will not touch a bacterial or yeast folliculitis, and on already inflamed skin it stings and can make things worse.
Permethrin 5% cream. The usual first treatment. It goes on the whole body from the neck down — every fold, between the fingers and toes, under the nails, around the navel and the genitals — and is left on for 8 to 14 hours, usually overnight. Put it back on your hands after any hand washing. It is repeated a week later to catch eggs that hatch after the first dose, and everyone in the household is treated on the same day whether they itch or not.
An older treatment, used where permethrin is unavailable or has not worked. It is applied the same way, over the whole body, and usually repeated. It stings on broken or scratched skin and can irritate, which is why it is rarely the first choice where permethrin can be had.
Precipitated sulfur in petrolatum, applied for three nights in a row. It is the option most often chosen for very young babies and is one your doctor may consider if you are pregnant or breastfeeding — ask them, since that decision is theirs to make with you. It smells strongly, stains clothing and bedding, and is greasy, which is the main reason people struggle to finish the course.
A steroid cream used after the mites have been killed, to settle the itch and the firm lumps left behind. It does nothing to the mites, and used on an undiagnosed itchy rash it blurs the picture while the infestation carries on spreading. So it is a second step, never a first one.
Marketed as both a scabies treatment and an anti-itch cream. It clears the mites in fewer people than permethrin does, so it is not a good first choice on its own. It is sometimes used for the itch after treatment, where it is mild and safe but not particularly effective.
An antibiotic ointment for scratched areas that have become infected — golden-yellow crust, oozing, soreness rather than itch. It has no effect on the mites at all. If the infection covers more than a small patch, or the skin around it is spreading red and swollen, antibiotic tablets are needed instead.
Clearing Staph from the nose. Some people carry Staphylococcus aureus in the nostrils or skin folds, which is one reason boils keep returning to the same person. A course of antibiotic ointment inside the nostrils, together with antiseptic washes and hot washing of towels and bedding, can reduce that. It is used for repeated boils rather than for a single episode, and it does not always hold, so household measures matter alongside it.
A lotion or solution for bacterial folliculitis spread over a wider area than an ointment can cover, such as the beard or the back. It is usually paired with a benzoyl peroxide wash, which both improves it and reduces resistance. It is not the answer if the same patch keeps returning, because that is a shaving, friction or occlusion problem rather than an antibiotic one.
Oral ivermectin. Tablets taken as two doses about a week apart, weighted by body weight. They are the practical answer when a whole household or a care home has to be treated at once, when cream cannot be applied properly, or when cream has already failed. For crusted scabies they are given together with cream, often repeatedly. Ask the prescribing doctor whether they suit you, since they are not used in very small children and are avoided in pregnancy.
A short course of antibiotic tablets when scratched skin has become properly infected — spreading redness, swelling, pain or fever. They treat the bacteria only, so the scabies treatment still has to be done alongside them. This is a common reason a scabies visit ends with two prescriptions rather than one.
An older antihistamine taken at bedtime, for the weeks when the itch is keeping you awake. Most of the benefit is that it makes you drowsy rather than that it blocks the itch, which in scabies is only partly driven by histamine. It is useful, it is short-term, and it can leave you groggy the next morning.
The usual first antibiotic tablet for bacterial folliculitis that is deep, spreading or too widespread for a cream, and for boils with surrounding redness. A course is normally about seven days. It has no effect on yeast folliculitis or razor bumps, and if the same area keeps flaring after each course, the cause is still there rather than the antibiotic being wrong.
Used when resistant Staphylococcus aureus is likely or has been grown on a swab, which is the situation in which the first antibiotic did not work. This is the main reason for swabbing a spot before starting treatment. It is avoided in pregnancy and with some other medicines, so tell the prescriber everything you take.
An antifungal tablet, usually a short weekly course, for yeast folliculitis that is widespread or has not cleared with washes alone. It works faster and more completely than topical treatment on the chest and back. The yeast lives on everyone and comes back, so it is normally followed by an antifungal wash once a week to hold it.
A longer course is sometimes used for stubborn or recurring folliculitis, partly for the bacteria and partly because it calms inflammation. It is a second choice rather than a first one, since it can allow yeast folliculitis to take hold. It also causes sunburn easily, so it needs daily sunscreen on anything the sun reaches.
Draining a boil. A boil that has come to a head is opened with a small blade under local anesthetic and the pus is let out, which relieves the pain almost immediately. It is often the whole treatment, with antibiotics only added if the redness is spreading. Done properly it heals with a much smaller mark than a squeezed boil, which is the argument for having it done rather than attempting it at home.
For folliculitis and razor bumps driven entirely by shaving, particularly in the beard and neck, reducing the hair removes the cause instead of treating the result. It usually takes six or more sessions and works best with a device suited to your skin tone, since the wrong one can burn or leave marks on deeper skin. It is worth considering after months of the same bumps rather than after one crop.
Itching can continue for several weeks after successful treatment, so itch alone does not prove that mites remain. New burrows or continuing new spots need reassessment; treating close contacts together helps prevent reinfestation.
Many superficial cases settle with appropriate care, but repeated episodes need assessment for an ongoing contributor such as shaving, friction or infection. The course depends on the type; deeper inflammation can take longer to heal and may scar.
Skin infection from scratching
Scratching breaks the skin and lets bacteria in, so scabies commonly turns into impetigo or, less often, cellulitis. The signs are pain rather than itch, golden-yellow crust, oozing, or spreading redness and swelling with fever. It needs antibiotics alongside the scabies treatment. In parts of the world where scabies is very common, these skin infections are also a route to kidney and heart problems later, which is one reason outbreaks are taken seriously.
Lumps that linger after treatment
Firm, itchy, red-brown lumps can stay on the genitals, groin and armpits for weeks to months after the mites are dead. They are a stubborn allergic reaction, not live infestation, and re-treating with scabies cream does nothing for them. A steroid cream from your doctor, and sometimes an injection into the lumps, is what settles them.
Weeks of broken sleep
The itch is at its worst at night, and by the time most people are diagnosed they have had several weeks of it. Broken sleep is the part that wears people down, and it usually carries on for another two to four weeks after treatment while the allergic reaction settles. It is worth treating in its own right — a sedating antihistamine at night, a cool bedroom and moisturizer before bed all help.
Boils and carbuncles
When the infection goes further down the follicle it becomes a boil: a tender, swollen lump that comes to a head over several days. Several joined together are called a carbuncle. Squeezing is what turns a surface bump into one of these, so warm compresses and leaving it alone are the right first move. Boils often need draining or oral antibiotics, and they can leave a scar.
Cellulitis
Sometimes the infection leaves the follicle and spreads into the surrounding skin. The signs are redness, swelling and warmth spreading outward from the spot rather than staying in it, sometimes red streaks running away from it, and often a fever. That is a same-day problem needing oral antibiotics, and it is more likely in people with diabetes or a weakened immune system.
Keloid scars
Deep folliculitis on the chest, shoulders, jawline and the back of the neck can heal into raised, thickened scars, and that risk is higher on deeper skin tones. At the nape there is a specific pattern, acne keloidalis nuchae, where the bumps become firm and permanent and the hair in that patch is lost. It responds far better to early treatment than to waiting, so firm bumps building at the back of the neck are a reason to be seen rather than to keep treating at home.
Arrange treatment for suspected scabies and close contacts. Crusted widespread rash or infection needs prompt assessment.
Arrange assessment if the rash persists, keeps returning, is extensive or has not responded to treatment. A pustule swab may help distinguish bacteria and guide treatment.
Seek prompt medical care for fever, rapidly spreading redness or warmth, worsening pain, a large deep lump, or feeling unwell. Seek care earlier if your immune system is suppressed.
Bumps around the eye with eye pain, swelling, light sensitivity or vision change need prompt assessment. Do not apply body washes or skin medicines into the eye.
Because the itch is an allergic reaction to the mites, not the mites themselves, and it takes two to four weeks to settle after they are gone. Moisturizer, antihistamines at night, and a steroid cream if your doctor prescribes one. Re-treating now irritates the skin. An itch worsening after four weeks does need review.
Cleanliness has nothing to do with it. The mite spreads through prolonged skin-to-skin contact - sharing a bed, holding a child, caring for a relative, sexual contact - and cannot be washed off once burrowed. Outbreaks happen in immaculate homes and hospitals.
Yes, on the same day, itch or not. Contacts can carry mites for four to six weeks before itching, so treating only the person with the rash almost guarantees it comes back. This is the most common reason scabies drags on.
You were contagious before you had symptoms, which is why it spreads so quietly. After a correctly applied treatment, most people are no longer contagious after about 24 hours. Many workplaces and schools use that as the point of return; follow local advice.
Not for ordinary scabies. Wash bedding, towels and clothing from the last three days on a hot wash and dry them hot, or bag them for about three days. The mite does not survive long off skin. Crusted scabies needs much more thorough cleaning.
Not the human form. Animals have their own mite varieties, which can cause a brief itchy rash on people but cannot reproduce on human skin and clear once the animal is treated by a vet.
Look for blackheads and whiteheads. Acne has them, folliculitis does not. Folliculitis bumps are all the same size, each sits at a hair, they itch more than they hurt, and they appear where you shave, sweat or rub - thighs, buttocks, beard, chest, back. Acne sits on the face, chest and upper back, has spots of different sizes, and is not itchy.
Mostly not in ordinary contact. The bacteria can pass through shared razors, towels, unwashed sports gear and close skin contact - avoid those while it is active. Yeast folliculitis and razor bumps are not caught.
Because the cause is still there - the shaving method, friction, damp clothes, or a yeast cause treated as bacterial. Some people also carry Staphylococcus aureus long term, which can be tested and treated.
Yes, but change how. A fresh single-blade or safety razor, with the grain, with gel, and no stretching the skin. Take days off while the skin is inflamed. For persistent razor bumps, laser hair reduction is a longer-term option.
Not on undiagnosed bumps. Steroid creams calm the itch for days while the infection carries on underneath, and the rash comes back more widespread. If itch is the main problem, a medicated wash and cool compresses are safer.
Superficial folliculitis heals without scarring, though flat dark marks take months to fade on deeper skin tones. Deep folliculitis and boils can scar, and firm raised bumps at the back of the neck can scar permanently - reasons to be seen early rather than keep treating at home.
