How often can I use a semi-permanent hair dye?

Which dye should I use to dye my hair?

• I want to dye my hair blue but I'm worried the colour will go to green, also which dye should I use to bleach my hair (my hair is red and purple at the minute). Is manic panic a good hair dye for the actual colour and will it dye my hair evenly with out bits of hair where the dye hasn't has dyed my hair properly. I was going to use atomic turquoise but will it look too much if I dye my hair all that colour if it does what other colour should I dye it and lastly do I need to mix it with another dye so the colour looks good because I've seen people do that before. I live in England if it makes any difference about which dye to use.

• Answer:

  I would definitely dye your hair brown first, as light brown as you can. Also, I use this stuff called color crazy to dye my hair, it has so many different colors, including blue. I use red to dye mine. It's easy enough to get out if it goes green but it stays in for soo long, despite being a semi-permanent dye which is great! It's also only like £2 a bottle, which is even better.
