I have had my license for 14 years and the color portion was by far the longest and detailed lesson of theory for any cosmetologist student. Lol so I always laugh when I walk by the “box color” in the grocery store. I think to myself there is no way possible you can get the results on the box unless you have prior education in correct color application. And most of the photos you see in the “box” are 3 dimensional coloring techniques that only an advanced level COLORIST could accomplish. Don’t be fool… Consult and stylist who is skilled in color before installing your extensions. Love your hair, Don’t abuse it!
