The Yarahair Glossary

The 4-Tier Integrity System.

From Single Donor Raw to Standard Remy, we classify hair based on two scientific variables: Donor Consistency and Processing Level.

Understanding the "Raw" Distinction

Why do we separate "Single Donor Raw" from "Raw Hair"? It comes down to consistency.

Single Donor vs. Multi-Donor

Single Donor Raw (15A): Because the hair comes from one person, the elasticity, thickness, and reaction to bleach/dye is identical throughout the bundle. It is the perfect canvas for professional colorists.


Raw Hair (9A-12A): This is still chemically unprocessed hair with intact cuticles. However, because it blends hair from multi donors, there might be slight variations in strand thickness. It is an excellent premium option at a more accessible price point.
