In Jainism there is no specific scriptural rule about when a baby’s first hair cut (mundan / first trim) must be done.

For shravaks (lay followers), hair cutting is treated as a normal cleanliness and grooming activity, not a religious samskar like in some other traditions.

So, when can the first haircut be done?

You may do it:

• At any age that is:

- Comfortable for the baby - Practically convenient for the parents - Safe and hygienic

There is no fixed tithi, nakshatra, or age given in Jain scriptures specifically for a baby’s first haircut.

What to keep in mind as a Jain

When you decide to do it, try to follow Jain principles:

1. Ahimsa (non‑violence)

- Choose a clean place and careful barber so minimum cutting/ pulling of skin and hair. - Prefer doing it in daylight so insects etc. are more visible and himsa is a bit less. - Avoid making it a big show that leads to extra waste, noise, or harm.

1. Sanyam & Aparigraha (restraint, non‑attachment)

- Keep the function simple, don’t turn it into a show of wealth or fashion. - Teach the child, as they grow, that hair and beauty are not everything; inner virtues matter more.

1. Shraddha (devotion)

- Many Jain families like to: - Visit the derasar (Jain temple) the same day - Do darshan, prarthana, and maybe alpa (small) daan in gratitude - This is a family tradition, not a compulsory Jain rite.

1. Avoiding special days of higher restraint

- On days like Paryushan / Das Lakshan, many Jains avoid cutting hair and nails as a personal vow of extra restraint. - So, preferably choose another day, before or after such festivals.

Digambar / Shvetambar view

• On this topic there is no major difference:

- Both consider hair cutting for laypeople as a worldly, hygienic act, not a religious samskar. - Special hair practices (kesh‑lochan, shaving for diksha) belong to monks and nuns, not to babies.

Summary: You may do your baby’s first haircut whenever it is safe and convenient, keeping it simple, minimizing himsa, and maintaining a Jain spirit of restraint and devotion. There is no fixed age or ritual requirement in Jain Dharma for this.
