Our verdict

A tidy at-home permanent color for covering greys in a light natural brown, with two complete kits. Mostly grey or red hair will not match the swatch exactly.

Overview

A bathroom sink at home is where this foam hair color does its work: mix the kit, dispense it through the foamer and massage the thick foam into roots without drips. The shade is a natural light brown, and an after-color conditioner finishes the job.

Drip-free foam that reaches roots and awkward spots makes home coloring less messy, and the brand claims full grey coverage. Results depend on the starting color: mostly grey hair turns out lighter than the swatch, and red hair goes light brown with a reddish cast.

Who it's for

Home colorers covering roots and greys in a light brown shade get two full kits here. People with mostly grey or red hair should expect a lighter or warmer result than the box swatch.

Pros and cons

Pros
  • Thick foam reduces drips
  • Two kits in the pack
  • Full grey coverage claim
  • After-color conditioner included
Cons
  • Mostly grey hair turns out lighter
  • Red hair ends up with reddish tones
  • Permanent, so mistakes need recoloring

Performance notes

The foam penetrates strands and spreads into roots and hard-to-reach areas, so coverage depends on saturating every section evenly. Starting color shapes the outcome, with grey and red hair shifting lighter or warmer than the swatch.
