color soft salerm purple

hi, i'm trying to dye a section of my hair purple, i'm using salerm color soft... i bleached it and left the dye for about half an hour but when i take it off its kind of light blue:S ive tryed so many times, i don't know what to do! the woman who sold it to me told me that the hair had to be white, i bleached it tons of times and got to the whitest color i could get, but it wasnt white white:S  i don't want it to be blue... please help!

Never bleach hair til it's white! Argh I don't know why she told you to do that. Once bleached past the pale yellow stage the hair will be far too processed to retain any colour. What's the condition like? You may have to use a protein filler and deep conditioner before the hair will hold any colour.

What's fallen off? The colour or the hair?

Yes, over bleaching causes irreversible damage to the hair, and if you have bleached it to white, then it is over done. To achieve white hair, hair must be bleached to the colour of the inside of a banana, then toned.

You don't need the hair to be white because you are only putting a darker colour over the top. Even the lightest 'crazy colours' only need to be applied to pale yellow hair. This over bleaching issue happens to girls that have been bleaching their hair for years, and when they decide to go dark, have a tremendously hard time trying to get the colour to 'stick'. This is because the bleach has affected the hair's porosity, which is the hair's ability to absorb liquid or moisture. In  this case the purple dye (which I'm assuming is a semi permanent - I'm not familiar with the brand).

Starting again would be ideal (is that even possible to cut it off???) or you could leave it blonde, if you're happy with the colour, and if it doesn't look too fried. Bleach to pale yellow, lightly shampoo, deep condition, apply the purple, leave on as long as possible, with heat is ideal. Let it cool down to set it, then rinse.

Perhaps you should go to a pro for the bleaching, and apply the purple yourself. Bleach can be very difficult to deal with, especially if you have colour in your hair already. It wouldn't be expensive for 1 or 2 chunks.

If you still want to do it yourself, answer me this.
- what bleach are you using?
- what developer strength?
- what's your hair's condition like?

Any pictures of your hair, and/or how you want it would be helpfull too.
