Crusty Scalp sores are more common than you might think. There are a few things that might cause this itchy and uncomfortable condition. Some of them are contact dermatitis, a viral infection, scalp acne, folliculitis, cyst, or skin cancer.

Some people experience crusty scalp sores with contact dermatitis, an irritant, or an allergic reaction to something. The usual culprit is chemicals in the many hair products we use. Crusty scalp Sores may also be caused by a viral infection. Some examples are chicken pox and shingles.

Folliculitis

If this is the case it is likely that the bumps will appear on other areas of the body as well. It is also possible for cysts to appear on the scalp as they do in other areas of the body. Folliculitis occurs when the hair follicle is left open due to an overly dry scalp. Bacteria then will become trapped causing the hair follicle to become inflamed and bumps or crusty sores to occur.

Scalp Acne

Acne can also occur on the scalp with many of the same causes we see for facial acne, hormones, and stress being two of the most common.  Both folliculitis and scalp acne may vary greatly from only a few bumps and pimples to large outbreaks with crusty sores. Skin cancer can occur on the scalp, most often in an area that has little or no hair covering it.

Shampoos and Other Solutions

If you have a mole that has grown or changed or a sore or irritation that will not go away it is a good idea to have it checked out by a dermatologist. Herbal-based shampoos that help to balance the scalp can be the best solution for long-term results for these types of problems. Drug-store and grocery-store shampoos can even lead to more damage to the scalp so be careful which products you choose.
