Frequently Asked Questions
Are hair fibers safe for children?
Many fibers are cosmetically safe when used correctly, but children’s skin can be reactive. Do a patch test, avoid inhalation and eyes, and consult your pediatrician if the child has a scalp condition.
How do I test for irritation?
Apply a small amount behind the ear or on the inner forearm, wait 24–48 hours, and watch for redness, itching or swelling.
How should I apply fibers to minimize risk?
Use a light hand, apply in a well‑ventilated area, keep the child still, and avoid spraying or fluffing over the face.
How do I remove fibers safely?
Wash hair gently with a mild shampoo; repeat if needed. Don’t scrub a sensitive scalp—use lukewarm water and gentle fingertips.
When should I try alternatives instead of fibers?
If the child has active scalp irritation, open sores, or a diagnosed condition, or if patch tests fail, choose cosmetic scalp coverups (soft scarves, hats) or consult a clinician for medical options.
