Answer

In Jain practice, it is generally better to do Samvatsari Pratikraman with neatness, modesty, and discipline. If your hair is wet, you may keep it arranged respectfully rather than leaving it loose in a distracting way.

There is no commonly known Jain rule that says wet hair must never be left loose during Pratikraman, but the main point is to maintain:

• Vinay — reverence and humility
• Shuddhata — cleanliness and purity
• Ekagrata — concentration
• Maryada — proper religious decorum

Explanation

During Samvatsari Pratikraman, the focus should be on repentance, forgiveness, self-reflection, and purification of the soul. If loose wet hair keeps touching your face, clothes, books, floor, or distracts you, it is better to tie it lightly or keep it covered/managed respectfully.

If tying wet hair is uncomfortable or not practical, you can keep it loose but arranged neatly so that it does not disturb your Pratikraman.

Spiritual Understanding

Jain Dharma gives importance not only to external discipline but also to inner purity. The most important thing in Pratikraman is sincere bhav — humility, repentance, and forgiveness.

So, hair arrangement should support your concentration, not become a cause of worry or distraction.

Takeaway

Yes, it is okay if necessary, but it is better to keep wet hair neat, modest, and non-distracting during Samvatsari Pratikraman.
