In Jainism, ahimsa (non-violence) extends to all living beings. Plucking hair to kill mites would involve harming those tiny jivas (life-forms) that reside on the hair. So from a strict ahimsa perspective, it’s better to avoid deliberately harming them.

What you can do instead:

• Maintain clean hygiene and regular washing with gentle, non-irritating shampoo.
• If you suspect mites or other skin/hair issues, consult a doctor or dermatologist for safe, non-violent treatments.
• Use non-harmful grooming methods (e.g., combing, gentle brushing) that don’t intentionally kill many microscopic organisms.
• Focus on overall scalp health: keep the scalp clean, avoid harsh chemicals, and follow any medical guidance.

If you’d like, I can explain how Jain texts describe ahimsa toward tiny life-forms in more detail, or point to related Jain practices for maintaining purity and health.
