Steven Hudson –
The colour is rich and natural-looking. I mixed it with the developer as instructed and achieved excellent coverage on gray hair. The hair feels soft and shiny after processing. No harshness or dryness, which is a big plus for daily wear.
Charles Johnston –
Good coverage on gray hair, especially in the mid-lengths. The shade is warm and balanced. I did need to apply a second coat for full coverage, but overall it’s a reliable product for professional use.
Victor Rampling –
I’ve used this colour several times now and it consistently delivers a natural brown tone with depth. The Me+ Technology seems to reduce irritation, which is helpful for sensitive scalps.
William Blake –
The colour is good, but it requires precise mixing. I accidentally used too much developer and the result was slightly too light. Following the instructions carefully helps achieve better results.
Ava Mackenzie –
Perfect for achieving a subtle, warm blonde brown. The shine is natural and the hair doesn’t feel damaged after processing. Works well with medium to thick hair types.
