Pros and cons

Pros

  • A short application time makes it a practical option for a quick colour refresh between brunette colour services.
  • The temporary, wash-out colour suits buyers who do not want a permanent dye commitment.
  • Customer feedback reports shine and softness, although results are not uniform.

Cons

  • The listing does not recommend it for grey coverage or bleached hair, so it is not a general-purpose colour solution.
