Dear Rabbi, I have a question on niddah (that I do not feel so comfortable to ask a local rabbi) I was wondering is it considered touching when brushing ones hair- i.e. would it be permitted for me to brush my husband’s hair during the time of being a niddah? Thank you so much, Kol tuv

Shalom, It is not permitted for a woman to brush her husband's hair when she is niddah. Kol Tuv
