I have light brown hair with bits of blonde in certain light. It can look a bit gingery in the sun too. No hair colour on it at the moment.
I want to use this semi permanent home dye to go black - https://www.amazon.co.uk/Clairol-Nicen-Easy-Gloss-Permanent/dp/B0DPNM4MDY
I have a couple of questions.
-
Will it fade out nicely and gradually or will I get a horrible green tint when the blue undertones mix with my slightly blonde tones?
-
How do you maintain a box dye? It says it lasts 28 washes, so how do I top it up? Do I just dye the roots or apply all over? I worry it's not possible to maintain a home dye job correctly without uneven bands of colour.
Thanks in advance!
