In Jain Dharma there is no scriptural rule that says you must wash hair on the 2nd or 3rd day of menstruation. Menstruation is a natural process. Maintain personal cleanliness as needed for health and comfort.

Common community practice: resume temple visits and dravya‑puja after the bleeding stops and after taking a full bath (snan) and wearing clean clothes. Customs can vary by family and sect.
