I've been wanting to use this product for a while as I've seen so many good reviews. Yesterday I got a bit experimental and tried it for the first time on my client.
I did a full head of highlights, two bleach with 6% to one wella 8/1 with 6%. My clients hair throws a lot of warmth, and I always use cool tones and toners to neutralize any warm tones. I knew she would be the perfect client to trial it on.
