Hair Loss Disorders (Alopecias)

The article discusses hair loss disorders, distinguishing between scarring and non-scarring alopecias. Diagnosis involves clinical history, examination, and potentially a scalp biopsy. Treatment aims to prevent further hair loss and encourage regrowth, though options may be limited. Emotional distress from hair loss is significant and should be acknowledged. A notable advancement is the approval of the Janus kinase inhibitor ritlecitinib for severe alopecia areata in patients aged 12 and older, offering a new therapeutic option for this challenging condition.
