Buying Notes
Choose plant‑based or 'natural' formulas if you have sensitive skin or react to fragrances. Match color to your roots, not the ends. Prefer fine fibers for thin/new baby hairs. Do a 24‑hour patch test on behind the ear. Apply fibers mostly to hair shafts (not directly rubbed into broken skin), use a light hand, set with a mild hold spray if needed, and wash them out nightly with a gentle shampoo. If you notice itching, redness, or irritation, stop use and consult your clinician.

Frequently Asked Questions
Are hair fibers safe while breastfeeding?
Fibers are cosmetic and generally safe, but avoid inhalation, apply in a well‑ventilated area, and do a patch test. If you have concerns, check with your healthcare provider.
How should I choose a shade?
Match fibers to your natural root color in daylight. If between shades, choose the darker one for more natural look.
How do I apply fibers without irritating a sensitive scalp?
Apply to hair shafts and part lines with a light hand or applicator; avoid rubbing fibers into broken skin. Use minimal hold spray and test first on a small area.
How do I remove fibers safely?
Use a gentle, sulfate‑free shampoo and lukewarm water nightly to avoid buildup on a healing scalp.
Will fibers interfere with hair regrowth?
Fibers are cosmetic and sit on existing hair. Keeping the scalp clean and not applying to inflamed/broken skin helps avoid irritation while hair regrows.
