Any hairdressers HELP with colour prob?

i'm a hairdresser (for 5 and a half years) who's just gone mobile. i'd prefer not to do colours really cause hair up's and cuts and blow drys are my skilled area really, but i don't think i'll ever be a strong colourist! anyways, i have a client tomorrow who is having full head woven highlights, she has dark roots, about a shade 4 or 5 i'd say, the ends are pre-coloured (not by me) and are a straw blonde sort of colour, her roots are like an inch and a half to 2 inches long and she wants full head woven with some darker shades going through (mid browns) and a few blondes all over too.


I use Affinage infiniti hair colours, and have a 8.32 that i was going to use (which is light sandy beige blonde) what peroxide should i use, i was going to use 20vol but i don't know whether to trust my own judgement? any help pleaasssee? i'd love to own my own shop really one day and just employ a colour technician!! lolAny hairdressers HELP with colour prob?
Trust your own judgement. 20 vol. will be O.K.Any hairdressers HELP with colour prob?
GOOD LUCK....try to talk her out of it or youl be reponsible for making her hair look even more like straw!!!!!!!
Your not going to use bleach for your hilites? Your going to use a high lift color? I've never had good luck w/ high lift colors especially if you don't have a dryer to put her under. I would use a semi perm. color (I use Redken Shades or Matrix) and I would use a level 7 for the low lite and very very thin because if she is that BLONDE then if you had too much dark in there she will not like it. I would use bleach w/ 20 volume and watch it because you don't know if she lifts quick or not. You can tone it if its gets to light but w/ 20 volume on that level of hair you should be okay if you watch it. If you have a dryer and you use the high lift color it usually calls for 20 minutes under the dryer and then 20 minutes sitting w/ no heat %26amp; usually it calls for 40 volume w/ a hilift blonde color. That's why have a better color result and it's not as damaging using bleach because you only have to use 20 volume rather then 40. ALways remember their natural level and what level your trying to get to. If someone was a level 7 and higher this highlift blonde might be better but her natural level is pretty dark to try and use a highlift color. Gooooood Luck and show confidence girl you know that...fake it till you make it...and if you know you can't make then don't do it!!!!
