Chaff
Chaff (medical)
Chaff (/ʧæf/), in a medical context, refers to the small, dry, scaly skin flakes that are shed from the body, particularly from the scalp. The term is derived from the Old English ceaf, meaning "husk of grain", due to the similarity in appearance between these skin flakes and grain husks.
Causes and Symptoms
Chaff is commonly caused by conditions such as dandruff and seborrheic dermatitis, which result in excessive flaking of the scalp. Other potential causes include psoriasis, eczema, and dry skin. Symptoms typically include an itchy scalp and visible white flakes in the hair and on clothing.
Treatment
Treatment for chaff often involves the use of medicated shampoos containing ingredients such as zinc pyrithione, salicylic acid, selenium sulfide, and ketoconazole. In severe cases, a healthcare provider may prescribe a stronger medication or recommend light therapy.
