Question:
I have scalp psoriasis which makes my scalp itchy and uncomfortable, can I wash hair with shampoo since it helps relieve the discomfort.
Answer:
Hello,
Yes, you may wash your hair (preferably under a faucet so that you don’t wash the rest of your body). If possible, and it will not disturb you too much, you should not wash on the first day of aveilus.
