How My Hair Felt After Coloring

One thing I appreciated was that my hair did not feel harsh after using it. My hair felt reasonably soft and manageable after rinsing and conditioning. I would not say it felt like a deep-conditioning treatment, but compared with some other box dyes I have tried, this one was gentler on my hair.

Gray Coverage Results I Noticed
