Hi! I'm getting blue highlights today and I only found the Semi-permanent hair dyes. Since it washes out between 6-12 hair dyes, and the bottle is quite big, will it damage my hair really badly if I dye it over and over again?

Please reply soon! :)

Hair dye isn't good for your hair, period, so you best bet might be to go to the hairdressr and just get one permanent dye.

Hair colors that are pink, blue or purple are known as unnatural colors. So there is no real "permanent" blue hair color. Semi-permanent hair colors are less damaging than permanent hair color. That's because semi-permanent colors contains a low percentage of peroxide and no ammonia in it. No, it won't damage your hair if you use it more than once.

I've found that colors don't really fade...
Like, they get lighter, but they don't leave
Until you dye over them,
I experienced this with pink, red, and blue...
