Thomas Oliver –
The colour is very natural and covers grey well without looking too artificial. My stylist mixed it with the developer and the result was smooth and shiny. I’ve used it twice now and it still looks fresh.
Benjamin North –
Good coverage on grey hair, especially in the roots. The ash tone is subtle and balanced. I noticed less damage compared to other permanent dyes I’ve used before.
Benjamin Graham –
The application was easy and the colour developed evenly. The shine is natural and not overly bright. I’m happy with the final result and would recommend it to other professionals.
Justin Bell –
It covers grey well, but the ash tone is a bit stronger than expected. I had to adjust the developer ratio slightly to get a more balanced look. Overall, it works but requires some experience.
Angela Mackay –
Used it on a client with mixed hair types. The colour blended smoothly and gave a warm, natural blonde with depth. No harsh lines or patchiness. Very satisfied with the outcome.
