Gray coverage and resistant hair
Gray coverage fails for a reason that is easy to state and easy to forget under pressure: there is nothing underneath to build on. Every technique on this page exists to compensate for that one absence.
| Why gray resists | It has no melanin and therefore no underlying pigment |
| What "resistant" means | A tightly compacted cuticle and low porosity |
| A hairline that keeps failing | Pre-soften the resistant area first |
| Blending a little gray with no lift | Demi-permanent color |
| Standard developer for gray coverage | 20 volume |
| About 70% gray, full coverage at level 6 | Add a natural or neutral base to the formula |
| Coarse resistant hair in a texture service | A stronger solution and a longer processing time |
Where the point is lost: Resistance is a porosity finding, not a color problem, which is why it shows up in the texture domain too. The same tightly packed cuticle that refuses tint also refuses waving lotion and relaxer, and in every case the answer is to change the product and the timing together — not to leave a normal formula on longer and hope.
