What are scalp scabs?
Scabs are the swelling of the tissues on your scalp that is brought about by scratching your head, putting on tight braids and pulling your dreadlocks or any other kind of injury that you make your scalp go through. The scabs at times resemble dandruff and in other situations, these may lead to other conditions like psoriasis. When untreated, these may lead to itch and odor.

This condition is scientifically called seborrheic dermatitis. When they occur, they come with such symptoms as itching and flaking, which are followed by the appearance of the crusty patches that seem to be white in color or yellow. Excess dandruff eventually makes scabs to appear. (Mayo clinic).
Severe dandruff makes the scalp skin become yellow with scaly pimples that appear around the hairline, behind the ears and the ack of the head. It is when the pimples rapture that the scabs come about. The eyebrows also end up being affected in some cases.

Shingles and ringworms
Shingles are viral infections that are brought about by herpes zoster. When they appear, you will notice patches and some crusts. The scabs on scalp form when the blisters bleed and then dry up.

The fungal infections form clusters that are called pustules around the area affected. The area then dries up and after scalp scabs and crusts form.
