Frequently Asked Questions
Can fibers match silver hair?
Yes — pick a cool gray/silver shade or mix a light and mid-gray; test in natural light to confirm.
How do I avoid a powdery look?
Apply fibers in thin layers, blend gently with your fingertips, then lock with a light-hold spray.
Should I buy a full jar or a sample kit?
If you’re uncertain about undertone, start with a sample kit; buy the full jar once you confirm the shade.
Can I mix shades for salt‑and‑pepper hair?
Yes — mixing two close shades (light + mid) creates a more natural salt‑and‑pepper effect.
How long do fibers last during the day?
They typically last until you wash them out; using a hold spray improves staying power.
