Actually I do care, I get it coloured once a year because sitting in the chair for 5 hours, yes 5 whole long hours puts me off. I love the results but it takes me a year to get over the trauma of being glued to a seat for that long.
I leave it to grow and grow and one day you decide enough is enough it is time to tame the mane. I may go out of my comfort zone this time and try something new. Maybe a two tone look, leaving the top black and having blond ends.
