I'm a hair stylist, 32 years. In reference to the post about asking a stylist for a house call during these times is illegal. For those of u with color and highlights, don't even attempt to color yourself, as application is key. If you're a level 6 or 7 light brown/dark blonde, I recommend a neutral 6N or 7N.
But truly, it's best to wait for your stylist. Self color correction is a pain for us, plus u could wind up with a band of unmatched color all over your head if your self attempt isn't great
