I get my hair dyed at the hairdresser (mostly grey hair) and my roots are about 1.5". I bought a box of Clairol nice and easy hair dye, but completely forgot that I'll probably need two boxes as my hair is long and extremely thick.
I've seen that clairol do a 'root touch up'. Is it the same as a regular hair dye, just not a smaller pack? The box I have is the closest match to my current colour. Can I just use it on my roots? Or are they different products?
I'm worried about starting to dye my hair all over and run out of dye.
