Bumps and flakes on the scalp can look similar at first, but scalp acne and dandruff are different problems. Treating one like the other can make it worse. Dandruff is usually caused by yeast and inflammation. Scalp acne is caused by clogged follicles and bacteria. The first step is to tell them apart.
What does scalp acne look like?
Scalp acne appears as red bumps, pimples, or sometimes painful cysts on the scalp. They may have a white head. They are usually localised, tender to touch, and can appear where hair is pulled tight or where products build up. Unlike dandruff, acne bumps do not usually flake off.
What does dandruff look like?
Dandruff shows up as white or yellow flakes on the scalp and hair. It is usually itchy and sometimes oily. The flakes are widespread rather than localised. It does not form distinct bumps, though an inflamed scalp can feel slightly raised in areas.
- Acne: red bumps, tenderness, no flakes.
- Dandruff: white or yellow flakes, widespread itch.
- Acne: caused by clogged follicles and bacteria.
- Dandruff: caused by Malassezia yeast and inflammation.
How do you treat each one?
For dandruff, use an anti-dandruff shampoo with Salicylic Acid and Piroctone Olamine. For scalp acne, keep the scalp clean and avoid heavy oils and pomades. A gentle cleanser and loose hairstyles help. Severe acne may need prescription treatment from a dermatologist. Never pick at scalp pimples.
What are the honest limitations of self-treatment?
Mild cases of both can be managed at home. But if bumps are painful, cystic, or leave scars, a dermatologist is needed. If dandruff is thick, greasy, and covers most of the scalp, it may be seborrheic dermatitis, which also needs professional treatment. Self-diagnosis is a starting point, not a final answer.
