In a simple way: Jain scriptures do not treat child hair-cutting as an important religious ritual.

What Jain Dharma clearly mentions is hair-plucking for monks and nuns during renunciation, as part of keśa-loca or keśa-lunchana. That is a monastic discipline, not a child ceremony.

For children, hair-cutting or tonsuring is generally seen as a family or social custom, not a core Jain scriptural duty.

So, the simple answer is:

• Monastic hair-plucking: yes, mentioned in Jain tradition.
• Child hair-cutting ritual: not a major scriptural Jain ritual.

If you want, I can also explain this in Digambar and Shwetambar understanding separately.
