Just after a little bit of advice/second opinion. I’ve currently started back working in the salon after a long break. A client came to me for roots done,she was blonde, I’d say her mods and ends are about a 12/0-10/38 i could tell it wasn’t bleached so used a 12/11, natural base 6-7 the colour looked fine, when she returned 6 weeks later she had said it had been ok but a little gold. So I used 12/89. It’s been about 4 weeks and has said it’s still too gold. She isn’t being funny at all and I appreciate her honesty. She is coming again on a few weeks for me to sort it but my question is what can I use now? And I’ve been using velvasilk (Alan Howard’s own brand) is significantly cheaper so I’m now wondering if this is the issue. So I’m considering using wella 12/96 for the next application. As this is the brand I train with albeit a good few years ago. I feel like I’ve had a great few weeks colouring and getting my confidence back and this is really throwing me. Can anyone please offer me some advice. Thanks in advance xx
