Hi , I have a regular client coming in today , and weve spent years getting her back to her natural salt and pepper . She has coarse base 5 hair and the previous colourist had left it yellow and brittle . Now she feels its dull and flat , but I'm really not keen to add any bleach as it will coursen her hair further . I'm thinking of either lowlighting with an 8 to blend and make more beige, or doing a semi all over to lift base half a shade and soften and tone white . Has anyone any ideas , it's really a lovely colour but I think she just feels old . Shes very conservative and wants low maintenance. Thanks
