colourwise i use 3, 5, 7, 9, 11 and bleach. i mix them to make what is missing, if that makes sense?
i also have a red. i use wella so 55/45, a gold, 8/3 and a ash 12/11, if i need anything else i wait till client has booked the appointment. i can usually funtion pretty smooth with them.
i also have the attacthment for the taps which was £2 fron teco in the bathroom department, but 99% have it washed over the bath, i found primark had cheaper towels than the whole salers and they washreally nice.
then u just need the other stuff as in hairspray, serum, blow wave spray, foils, streaking cap, bowls brushes, perm rods, setting rollers, combs brushes, hairdryer ovb... lol
i use bedhead on clients and if they wish to purchase any i say one week and get it from the wholesalers and add a few quid on, it works well.
hope this helps and best of luck xxxxxxxxx
