First off, to even access Aveda hair color, you must be a licensed cosmetologist or barber AND work in a licensed Aveda salon. To get to that point means going to cosmetology school which takes roughly 1500+ hours (let's call it 10 months) and costs around $20,000. It's not the easiest of things to get through but it is a lot of fun!
Next, let's talk about training. At Thirty Hair, before starting on the floor solo, our stylists go through large amounts of training (We are talking 2-3 months) on everything from the basics to the extremes of hair. Our hair color training alone is one third of the time! And that's after they've completed school! Training includes memorizing the color wheel (which is vital), learning what colors remain, how to use the lowest developer possible to keep the hair healthy, and how to correct color (like that time you tried to manic panic your hair pink and now have a big job interview that you can't possibly show up with faded pink/orange hair for!)
The big difference with those boxes of color versus our boxes of color is that our boxes need to be custom blended to get your hair color. We look at the color you want to be, the color you have on your head, and formulate from there! Sometimes it even takes multiple formulas depending on what you want, any regrowth you have and the previous color on your ends!
