What causes scalp discoloration?

Scalp discoloration can be caused by several factors, including skin conditions like psoriasis or eczema, which lead to inflammation and changes in pigmentation. Sun exposure can also contribute to discoloration, as UV rays can darken or lighten the skin. Additionally, hormonal changes, certain medications, and allergic reactions to hair products can result in uneven skin tone on the scalp. In some cases, poor circulation or underlying health issues may also play a role.
