What You Need To Know
If your hair color sits between catalogue shades or is an uncommon tone, mixing or tinting hair fibers can get you a closer match. This guide focuses on safe, low-risk approaches: blend existing fiber shades first, use small tests, and only consider dyeing fiber samples after you’ve confirmed results. Below are the key tools, step-by-step safety tips, and practical mixing ratios for common tricky shades.

How to custom-tint or mix hair fibers to match unusual or custom shades
RB RENATA BEAUTY Tint Kit is the only dye here — useful for controlled sample tinting but higher-risk for fibers. Colortrak bowls and mini brush sets are the practical mixing tools: bowls for batching and the mini brush set for precise spot mixes and root-detailing. BOLDIFY and THICK FIBER are the fiber products to blend — BOLDIFY is fine and natural-looking for subtle layering; THICK FIBER gives denser coverage for bolder mixes. For most custom shades, blend fiber shades first; use the dye kit only for very small sample adjustments after testing.

Buying Notes
Start by choosing a base fiber close to your dominant hair color. Use small bowls and detail brushes to make test batches, and mix in small percentage steps (5–10%) until you hit the target. Prefer physical blending of fiber colors over chemical tinting — it’s reversible and safer. If you do use cream dye for test samples, keep it to tiny sample amounts, use proper gloves and ventilation, and never assume dye will behave the same on fibers as on hair. Label every batch, record ratios, and discard mixes that change texture or smell.

Frequently Asked Questions
Can I dye hair fibers with regular hair dye?
Generally avoid dyeing full fiber batches. If you must test dyeing, do a tiny sample first, use gloves and ventilation, and treat results as non-guaranteed. Many brands don’t intend fibers to be chemically dyed.
What’s a safe way to get an exact match?
Physically mix small amounts of two or three fiber shades in 5–10% steps and evaluate in natural light. Record ratios that work.
What ratios should I start with?
Start with 90/10 for subtle shifts, 80/20 for noticeable changes, and 70/30–60/40 for clear two-tone effects. Adjust in 5–10% increments.
How do I test a mixed batch?
Place a pea-sized sample on a white paper or cloth, let it sit and dry, then compare in daylight. Don’t test on skin.
How long will a mixed sample keep?
Store dry mixes in small airtight containers away from light; use within 1–2 weeks for best consistency.
How should I clean mixing tools?
Wipe excess fibers out first, then wash bowls/brushes with warm soapy water. For dye staining, use isopropyl alcohol sparingly and let items air-dry.
