Psoriatic arthritis (PsA) can indirectly cause hair loss due to related conditions and treatments. Psoriatic alopecia is hair loss associated with psoriasis or the medications taken for PsA or psoriasis. Scalp psoriasis can lead to thinning hair and bald spots. Inflammation and scratching can further damage the scalp, making hair growth difficult. To manage hair loss, consult a dermatologist, use psoriasis-friendly shampoos, avoid hot showers, minimize hair dryer use, and maintain a healthy diet. Increasing vitamin D levels may also help. Early intervention is crucial, so contact your healthcare provider if you notice hair loss.
