What is a common sign of scalp disease that barbers should look out for?

Flaking or redness on the scalp is a key indicator of potential scalp diseases, such as psoriasis, dermatitis, or fungal infections like ringworm. Barbers should be attentive to these signs because they can signify underlying health issues that may require referral to a medical professional. Recognizing such symptoms is crucial, as they not only affect the client's comfort and hair health but also eliminate the risk of spreading infections in the barbershop environment.

An oily scalp can be a common trait for many individuals and does not typically indicate disease, while dry hair strands may relate more to hair care rather than scalp health. Sensitive skin on the hairline could indicate irritation or an allergic reaction but is not as definitive a sign of a scalp disease as flaking or redness. Therefore, being vigilant about flaking and redness enables barbers to maintain a safe and healthy salon environment while effectively caring for their clients.
