Fast answer
Itchy bumps on the scalp may be caused by inflamed hair follicles, product irritation, dandruff, eczema, psoriasis, head lice or a fungal infection. Some bumps are small and settle when the trigger is removed, while others may need treatment from a pharmacist, GP or dermatologist.
Avoid scratching, picking or squeezing the bumps. Wash gently, rinse products away thoroughly and stop using anything that causes burning, swelling or increasing irritation.
Seek professional advice if the bumps are painful, filled with pus, spreading, repeatedly crusting or accompanied by fever, swollen glands or hair loss.

What are the itchy bumps on my scalp?
The word bump can describe several different changes in the skin. It might refer to a tiny raised spot, a firm lump beneath the skin, a small blister, a crusted area or a spot containing fluid or pus.
Appearance alone is not always enough to identify the cause. It can help to consider:
- Whether there is one bump or several
- Where the bumps appear
- Whether they are itchy, painful or tender
- Whether they contain fluid or pus
- Whether the surrounding scalp is flaky or inflamed
- Whether hair is thinning around the affected area
- Whether a new product was used before the bumps appeared
It is also worth noticing whether the bumps come and go or keep returning in the same area.
Scalp folliculitis
Folliculitis means inflammation around a hair follicle. On the scalp, it may appear as small raised spots or pustules that can feel very itchy, sore or tender.
The spots may be more noticeable around the hairline, although they can occur elsewhere. Scratching may cause them to become crusted or painful.
Folliculitis can have several possible causes. Bacteria, yeasts, irritation and inflammation may all be involved. This means that the correct treatment depends on what is causing it.
Do not squeeze spots that you suspect may be folliculitis. Squeezing can damage the surrounding skin and may increase the risk of further inflammation or infection.
Recurring, painful or pus filled spots should be assessed by a pharmacist, GP or dermatologist.
Contact with shampoo or styling products
Shampoo, conditioner, hair dye, fragrance and styling products can irritate the scalp or cause contact dermatitis in some people.
A product reaction may cause:
- Itching or burning
- Small raised areas
- A visible rash
- Dryness or cracking
- Swelling
- Blisters in a stronger reaction
Stop using any new product that appears to have triggered the reaction. Rinse the scalp carefully with lukewarm water and avoid adding several new products while the skin is unsettled.
If bumps or itching appear after washing, read our guide explaining why your scalp may itch after washing your hair and how residue, water temperature and cleansing habits may contribute.
Seek urgent medical help if a reaction causes swelling of the lips, tongue or face, or affects breathing.
Dandruff and seborrhoeic dermatitis
Dandruff usually causes loose flakes and itching rather than distinct bumps. However, repeated scratching can irritate the skin and create small raised, broken or crusted areas.
Seborrhoeic dermatitis can cause more noticeable inflammation, greasy or flaky scale and discomfort around the scalp, hairline, ears or face.
Do not assume that every itchy bump is dandruff. Persistent redness, pain, pus or hair loss deserves a closer assessment.
Scalp psoriasis
Scalp psoriasis usually causes clearly defined areas of scale rather than isolated spots. However, the surface may feel uneven or raised, and scratching can damage the skin underneath.
Trying to pull away a plaque may cause cracking, bleeding and additional irritation. Allow scale to soften gradually and follow any treatment recommended by your doctor, pharmacist or dermatologist.
If you are uncertain whether a raised area is a psoriasis plaque, dandruff or another scalp condition, seek professional advice before attempting to remove it.
Scalp eczema
Eczema can leave the scalp dry, inflamed and intensely itchy. Scratching may create small raised or broken areas and increase the possibility of infection.
Signs that eczema may have become infected include increasing pain, warmth, swelling, weeping, crusting or pus.
Medical advice is important if these changes develop, particularly if the affected person feels unwell or develops a high temperature.
Head lice
Head lice can cause an itchy scalp, and their bites may be noticed as tiny irritated areas. Repeated scratching can create sore or crusted bumps.
Itching alone does not confirm head lice. The most reliable way to check is to look carefully for live lice using a suitable detection comb. Empty egg cases can remain attached to the hair after lice are no longer present.
A pharmacist can advise on suitable detection and treatment. Speak to a healthcare professional if scratching has caused significant soreness, crusting or possible infection.
Fungal infection of the scalp
Ringworm affecting the scalp is called tinea capitis. It can cause itching, scale, raised or inflamed areas and patches of hair loss.
Scalp ringworm usually requires prescribed treatment. Creams used for ringworm elsewhere on the body may not be sufficient when the scalp and hair follicles are affected.
It can spread between people and through shared combs, towels or bedding. It may also be passed through contact with an infected animal.
Seek medical advice if a child or adult develops a scaly area with broken hairs, patchy hair loss, swelling or painful glands in the neck.
Could the bump be a scalp cyst?
A scalp cyst may feel like a smooth, firm lump beneath the skin. It may not itch unless it becomes irritated or inflamed.
Do not attempt to puncture or drain a scalp lump yourself. A lump that grows, changes, becomes painful or repeatedly becomes inflamed should be examined by a healthcare professional.
Why scratching and squeezing can make bumps worse
Itching can create a strong urge to scratch, particularly when the scalp is difficult to see. Scratching with fingernails may break the skin and move bacteria into an already irritated area.
Picking and squeezing may increase:
- Inflammation
- Pain and tenderness
- Bleeding
- Crusting
- The risk of infection
- The possibility of scarring
Keep fingernails clean and short. A cool, clean compress may feel more comfortable than scratching, but avoid pressing forcefully on painful or pus filled areas.
Why scalp bumps may feel worse at night
Itching can feel more noticeable when you are resting because there are fewer distractions. Warmth from bedding and perspiration may also increase awareness of existing irritation.
If scalp discomfort repeatedly interrupts your sleep, read our guide to why your scalp may itch at night and which patterns are worth discussing with a healthcare professional.
Can menopause contribute to scalp itching?
Changes during menopause may coincide with increased skin dryness or sensitivity. This can make an existing scalp problem feel more uncomfortable, but menopause does not explain every raised spot or scalp lump.
Pus filled bumps, spreading redness, marked swelling or broken hairs require a proper assessment rather than being attributed to hormonal changes alone.
Our guide to menopause and an itchy scalp explains how changing skin and hair needs may affect scalp comfort during this stage of life.
A gentle routine while the cause is unclear
Until you understand what is causing the bumps, keep your routine simple.
- Wash with lukewarm rather than very hot water.
- Use a gentle shampoo and only the amount needed.
- Massage carefully with your fingertips.
- Do not scrub with your fingernails.
- Rinse shampoo and conditioner away thoroughly.
- Pat the hair gently rather than rubbing vigorously.
- Keep styling products away from active bumps.
- Do not introduce several new products at once.
This routine may reduce avoidable irritation, but it does not replace diagnosis or treatment when infection, fungal disease or another scalp condition is suspected.
Choosing a gentle shampoo
When the scalp is dry or easily irritated, a gentle cleanser may feel more comfortable than a strongly fragranced or intensive cleansing shampoo.
Bragan Skincare Shampoo for Sensitive Scalp is designed to cleanse dry, itchy and sensitive scalps gently while supporting everyday comfort.
It may provide a suitable cosmetic cleansing option when the skin is intact and a gentler routine is needed. It is not intended to diagnose the cause of scalp bumps or replace prescribed treatment.
Avoid applying cosmetic products directly to open, bleeding, weeping or visibly infected areas unless a healthcare professional has advised that they are suitable.
Supporting dry areas between washes
Some people notice dry or tight areas alongside their scalp bumps. A lightweight leave in product may help support moisture where the skin is intact.
Bragan Skincare Scalp Soothe Leave In Treatment is designed to support dry, tight and uncomfortable areas between washes.
Start with a small amount on a limited area and stop if irritation develops. Do not apply it directly to pustules, open wounds, weeping skin or areas that may be infected.
You can explore both products and further options in the Bragan Skincare scalp care collection.
Itchy bumps accompanied by hair loss
Some conditions that produce scalp bumps can also affect the hair. This may happen because of inflammation, infection, scratching or damage around the hair follicles.
Seek professional advice if you notice:
- Sudden or patchy hair loss
- Broken hairs around a scaly area
- A smooth or shiny patch of scalp
- Several hairs emerging together from one inflamed follicle
- Hair loss that continues as the bumps spread
Our guide to itchy scalp and hair loss explains possible causes and when this combination needs professional assessment.
