Sore Scalp: Common Causes of a Tender Scalp and What Helps

A sore scalp is a strange complaint to have. It hurts to brush your hair, to tie it up, sometimes just to lie on a pillow, and yet when you look there is often nothing to see. People describe it as tender, bruised, burning, prickly, or “my hair hurts.” Most of the time the cause is ordinary and fixable. Occasionally it is a sign of something that needs a doctor quickly, and the difference is usually clear once you know what to look for.

This guide runs through the causes of a sore scalp from the most common to the rare, explains how to tell them apart by where it hurts and what comes with it, gives the fixes for each, and lists the handful of symptoms that mean same-day care.

Why does my scalp hurt? The common causes

1. Tension in the scalp muscles

The scalp is wrapped in a thin sheet of muscle that connects the forehead to the back of the head. Stress, clenching, long hours at a screen, and poor sleep tighten it, and a tight scalp aches the way a tight shoulder does. This is the same mechanism as a tension headache, and the two often come together: a band of pressure around the head, tenderness when you press the scalp, and soreness that is worse at the end of the day. It is the single most common cause of a sore scalp with nothing to see.

What helps: a few minutes of gentle fingertip massage, heat on the neck and shoulders, stretching the neck, managing the stress behind it, and regular breaks from the screen. Over-the-counter pain relief is fine for a bad day but is not a plan.

2. Tight hairstyles and hair weight

Ponytails, buns, braids, extensions, and weaves pull on the follicles for hours at a time, and the pull itself hurts, especially at the hairline and crown. A heavy head of long hair tied high does the same. Over months this is also how traction alopecia starts, so a scalp that hurts when your hair is up is a warning worth hearing. Headbands, tight hats, and helmets cause a similar pressure pain.

What helps: wear hair down or in a loose, low style, change the position of the part and the tie each day, take out extensions for a while, and never sleep with hair pulled tight. The soreness usually fades within days of loosening it.

3. Sunburn

The scalp burns easily along the part, at the crown, and anywhere hair is thin, and people rarely notice until it hurts to brush. Sunburn pain peaks a day or two after exposure, with redness, warmth, and later flaking.

What helps: cool showers, aloe or a plain moisturizer, pain relief, and a hat or scalp sunscreen next time. Regular scalp sunburn raises the risk of skin cancer on the scalp, which is hard to spot under hair, so it is worth preventing rather than treating.

4. Dandruff, seborrheic dermatitis, and psoriasis

Inflamed scalp skin is sore as well as itchy. Dandruff and its heavier cousin seborrheic dermatitis cause greasy yellowish flakes, redness, and a tender, itchy scalp, worst along the hairline and behind the ears. Scalp psoriasis causes thicker, silvery, well-defined plaques that can crack and feel raw. The American Academy of Dermatology notes that seborrheic dermatitis tends to flare with stress, cold dry weather, and illness, which is why a sore scalp often shows up at the worst time. Eczema (atopic dermatitis) can affect the scalp too, with dry, very itchy, sore patches that may weep or crust, often along with eczema elsewhere on the body.

What helps: a medicated shampoo with ketoconazole, zinc pyrithione, selenium sulfide, or coal tar, used two or three times a week and left on for five minutes before rinsing. Salicylic acid shampoos lift thick scale. Psoriasis plaques that do not respond need a prescription steroid solution or foam from a doctor. A dry, flaking scalp without redness is a different and milder problem; our guide to dry scalp causes and treatment covers how to tell them apart.

5. A reaction to a hair product

Hair dye is the big one, specifically a chemical called PPD in most permanent dyes, but shampoos, conditioners, styling products, and fragrance can all cause contact dermatitis. The scalp burns, stings, itches, and can swell, usually within a day or two of the product, and the hairline, ears, and neck often react too. A burning scalp during bleaching or a relaxer treatment is a chemical burn and needs the product rinsed off immediately.

What helps: stop the product, wash with a plain fragrance-free shampoo, use a cool compress, and see a doctor for a short course of steroid if the swelling is marked. Patch test any new dye on the inner arm 48 hours before using it, every time.

6. Folliculitis and scalp acne

Infected or inflamed hair follicles show as small red or white bumps that are tender to touch, sometimes with a crust. Sweat under hats, heavy conditioners, and not washing after exercise are common triggers. A larger, deeper, very painful lump with pus is a boil, and a smooth lump under the skin that slowly grows is usually a cyst. Do not squeeze either one; show it to a doctor.

What helps: warm compresses, washing after sweating, an antibacterial or antifungal shampoo, and keeping hands off the bumps. Spreading or painful lumps need antibiotics from a doctor.

7. Trichodynia: when your hair itself seems to hurt

Some people with hair shedding describe a burning, tender, or prickling scalp that feels as if the hair follicles themselves hurt. Doctors call it trichodynia, and it most often goes with telogen effluvium, the temporary all-over shedding that follows a shock to the body such as illness, surgery, childbirth, crash dieting, or a stressful few months. The pain usually starts a little before or alongside the shedding and eases as the hair recovers. It is also reported with female and male pattern hair loss. If a sore scalp has come with more hair in the brush, our guides to what causes hair loss in women and hair loss in men explain what is likely going on and what helps.

Less common causes worth knowing

• Migraine. During and after a migraine the scalp can become so sensitive that brushing hurts, a symptom called allodynia. It fades with the attack.
• Occipital neuralgia. Irritation of the nerves that run from the neck over the back of the head causes sharp, shooting, or electric pain on one or both sides at the back, with a tender spot at the base of the skull. Often triggered by neck posture or injury.
• Head lice. Itching more than pain, but constant scratching makes the scalp sore. Look for nits glued to hairs near the scalp behind the ears and at the nape.
• Ringworm of the scalp. A fungal infection, mostly in children, causing scaly, sore, sometimes bald patches. It needs prescription antifungal tablets.
• Cold or wind exposure, which tightens the scalp and dries the skin.

The two causes that need a doctor the same day

Shingles

Shingles is the chickenpox virus reawakening along a nerve. On the head it causes pain, burning, or tingling on one side of the scalp or forehead, followed within a few days by a stripe or patch of blisters that never crosses the midline. The NHS advises seeing a doctor as soon as you suspect it, because antiviral tablets work best in the first 72 hours, and shingles near the eye can damage sight. One-sided scalp pain with any rash is shingles until proven otherwise.

Giant cell arteritis

In people over 50, a new tender scalp, especially at the temples where it hurts to comb or wear glasses, together with a new headache, jaw pain when chewing, tiredness, or any change in vision, can mean inflammation of the arteries in the head. The NHS classes this as urgent because untreated it can cause permanent loss of sight within days, and steroid treatment prevents that. It is uncommon, but it is the reason a sore scalp in an older adult should not be waited out.

How to tell what is causing yours

Simple care for a sore scalp

• Wear hair loose or low for a week and skip extensions, tight hats, and heavy headbands.
• Switch to a gentle, fragrance-free shampoo, and wash with lukewarm water rather than hot.
• If there is flaking or redness, use a medicated dandruff shampoo two or three times a week.
• Massage the scalp with your fingertips for two or three minutes a day to ease muscle tension and improve circulation.
• Protect the scalp from sun with a hat or a spray sunscreen along the part.
• Stop any product you started in the last few weeks and see whether the pain fades.
• Deal with the stress, sleep, and screen posture behind tension pain, because the shampoo cannot.

When to see a doctor

Same day: one-sided pain with a rash or blisters; a tender scalp with a new headache, jaw pain, fever, or any change in vision, especially if you are over 50; a scalp that is swollen, hot, or has spreading painful lumps; or severe pain after an injury. Within a week or two: a sore scalp that has not improved with the steps above, thick scale or bald patches, pain that keeps you awake, or hair shedding that is increasing. A doctor can usually tell the cause by looking and can prescribe the steroid, antifungal, or antibiotic treatments that over-the-counter products cannot replace.

The bottom line

A sore scalp is usually tension, a tight hairstyle, sunburn, inflamed skin, a product reaction, or the tenderness that comes with hair shedding, and each of those has a straightforward fix that works within a couple of weeks. The exceptions are one-sided pain with blisters, which is shingles, and temple tenderness with headache, jaw pain, or vision changes after 50, which is giant cell arteritis. Both need a doctor today. For everything else, loosen the hair, calm the skin, ease the tension, and give it time.
