Stephanie Carr –
The peroxide delivered strong colour coverage with even results. Grey hair was fully covered without any patchiness. Works well with my salon’s colour formulas.
Joanne Simpson –
Good performance for grey coverage. The 6% strength is effective without being too harsh. I’ve used it in multiple sessions and it remains consistent.
Sarah Reid –
Excellent for achieving a natural, even tone. The 990ml size is convenient for regular use. No noticeable damage to hair after several applications.
Ruth Wright –
Works as expected, but the coverage on very fine hair was a bit uneven. Might need to adjust application technique.
