Bleach totally ruins hair, so make sure to get some deep conditioning treatments to keep it nice! The ends of my hair are still really damaged and I haven't had any bleach or colour for atleast a year! But if your hair is fairly light naturally then the damage should be minimal as the bleach would require less time!

Any bright colour will fade mega quick on bleached hair so I'd probably go for the full colour and just wait for it to fade and use colour shampoo & conditioner to try and retain the colour I wanted.

I really like the blue and the purple! I'm leaning towards the purple.
