I have used Crazy colour for years now and have used practically every shade either on myself or my friends and families hair. I can tell you that none of the colours will be as vivid as you expect them to be if your hair is not a light blonde colour, your hair needs to be a minimum of a medium blonde otherwise you will not get the desired effect. Also consider that these dyes are semi permanent and despite the average 3-9 week estimation for how long the dyes last, this all depends on the health of your hair. The dye is less likely to hold if your hair is damaged and over processed so do not expect miracles if this sounds like your hair condition - however this does not  Read the complete review

So today I received my Crazy Color, yay! I ordered this off Ebay about 6 days ago, it felt like I waited a life time for it to come..and when the post lady came this morning, I could of give her a hug! --------------- THE CLAIMS --------------- Crazy Color is a hair dye by Renbow I think they are called.

A few years ago, before I knew much about hair dye I was constantly searching for some really vibrant and bright colours like these. I started colouring my hair at home using "box colours" and always went for the pinky/purple shades but I was always disappointed because they never looked like they did on the front of the box and they were never as bright as I wanted. After scouring the net I came across the Renbow site and stumbled upon the Crazy Color range. I couldn't believe my luck! The packaging of this product is quite primitive and leaves a lot to be desired. Ok so the bottle is pink, that's one good thing about it but the Crazy Color logo is ...  Read the complete review

I have had different coloured hair for about 2 years now. my hair is naturaly very dark brown so it is difficult to get any colour to dye over it. So when I decided I wanted pink hair I tried Reinbow Crazy Colour. I tried the bright pink one straight over my natural hair colour and it didnt show up at all. A few days later I bleached it as bright as possible then applied the pink. The pink showed up extremely vibrant, better than expected. I have a few problems with this product though! No matter what colour you choose, and there is a wide range available, from dark red to bright green, they dont stay in long. I know its only a semi-permenant dye ...  Read the complete review

I used to have the bottom layers of my hair a very bright pink. The dye I used was this brilliant permanent stuff that I could get from Superdrug and Boots but this seems to have disappeared. I have been on the hunt for something similar for a while and was not having much luck. In the end I went to a beauty wholesalers and the woman pointed me in the direction of Reinbow colours. I bought a bottle of it for something around £5.50. It is a semi permanent dye. The dye comes in a flip cap bottle. You are not given any gloves or conditioner so you will need to provide this yourself. The range is called crazy colours and you can get all different colours ...  Read the complete review
