Yea we had this problem when I was in college, it does make you learn how to mix colours in a way other students will never learn, the prob in our college was funding, they bought tons at the start of each year but never topped it up through the year, when level 2's & level 3's are using it day in day out it dosent last long! We started out with all goldwell, peroxides bleach & colours, by January we were using wholesalers peroxide & bleach that people brought in and standing in the dispensary for 20 mins racking our brains on how the heck we were going to create the colour the client needed without the actual colour! All well and good with browns/blondes but a nightmare when ur doing reds & purples! Just take your own in if u know what ur going to need
