What causes Scabs on the scalp?

Scabs on the scalp can be caused by various factors, including skin conditions like psoriasis, eczema, or seborrheic dermatitis, which lead to inflammation and flaking. Injuries or trauma to the scalp, such as scratching or hair pulling, can also result in scabbing as the skin heals. Additionally, infections, such as fungal or bacterial infections, might contribute to scab formation. Allergic reactions to hair products or other irritants can further aggravate the scalp and lead to scabs.
