Scabs on the scalp are more than just a nuisance. They cause itching, irritation, and pain. In most cases, they shouldn’t be a real cause for concern, but they shouldn’t be overlooked.
It is also essential to give them proper management so they do not generate complications. Scabs on the scalp encourage frequent scratching, making them worse or leading to an infection.
The most important thing to take into account is its intensity and spread. If they appear only occasionally, it is a routine problem. If they spread quickly, it’s time to see a doctor.
There are many reasons why scabs can appear on the scalp. The following are the leading causes of this condition.
Lice live on the scalp and feed on blood. Their bites are itchy, and scratching can cause sores and scabs to form. Although they are not carriers of disease, scratching can lead to superinfection.
2. Contact dermatitis
Contact dermatitis manifests as a red, itchy rash. It is caused by exposure to allergens often present in soaps, shampoos, cosmetics, or plants. As with head lice, scratching can lead to sores and scabs on the scalp.
3. Dermatitis herpetiformis
This chronic skin condition occurs in people with celiac disease or gluten sensitivity. The lesions look like clusters of blisters on the skin or along the hairline.
They cause an intense itch, and sometimes there is burning before they appear. Scabs form that almost always disappear in 1 to 2 weeks.
4. Seborrheic dermatitis
Seborrheic dermatitis is a condition in the sebaceous areas of the scalp. It causes patches of oily skin to appear in the form of white or yellow scales, dusty.
If they scratch, they can give rise to scabs. It is also known as cradle cap and may be caused by an overgrowth of yeast.
Psoriasis is a chronic inflammatory pathology of the skin. Sometimes it generates scabs on the scalp, accompanied by dandruff flakes and thick plaques.
These are gray or silver and appear without previous scratching. Psoriasis often also occurs on the elbows, knees, and trunk.
When eczema appears on the scalp, it does not cause scabs. As in other cases, it is the itching that leads to continuous scratching.
This condition also generates dryness, inflammation, and irritation in the area. Sometimes it is accompanied by a burning sensation.
Shingles is a skin rash that can be very painful. The same virus causes it as chickenpox and leads to blisters.
When the blisters break open, scabs may form on the scalp. This disease is also known as shingles.
