In Jain Dharma, there is no scriptural rule that says a girl/woman cannot wash her hair on the 6th day of periods.

From a Jain point of view:

• Menstruation is a natural bodily process, not a sin.
• Cleanliness (shauch) is always encouraged.
• Jain scriptures do not fix any specific day (2nd, 3rd, 6th, or 7th) for hair wash.
• You may wash your hair whenever needed for hygiene and comfort.

Common traditional practice (family/custom based, not strict Dharma rule):

• Many Jain families pause temple/puja-related activities during bleeding days.
• After periods end, they do a full bath with head wash and wear clean clothes before resuming mandir/puja.
• The exact day (3rd, 4th, 5th, 6th…) varies by family maryada, not by Shwetambar or Digambar scripture.

So, yes, you can wash your hair on the 6th day of your period. Just keep in mind:

• Prefer bathing and hair wash in daytime.
• Use only necessary water (following ahimsa).
• Follow your family/sangh maryada if they have a particular rule, knowing it is a custom, not a strict Agamic command.
