- do i need to bleach my hair?
Yes, cos you have dark hair. - how long will it last?
Well first of all how long do you want it to last? If you use semi-pernament then it will last maybe just a couple of weeks. if you use pernament then it will last until your hair grows out BUT it will fade...fading is going to be your big problem. All colours fade and this will be most pronounced with bright colours. Though it will start bright and fruity it will quite rapidly become pale, in some cases it I've seen it fade away completely!
IMPORTNAT: invest in colour preserving shampoo and conditioner, this will prolong the colours vitality, make it take longer to fade!
- can i do it myself or do i have to get it done in a salon?
Its a hell alot more expensive at the salon, but you will (most likely) get a better job of it. With bright colours messing up can be more obvious which sucks, but some salons charge like £70 for whole head of colour. - will it work cos my hair is dark?
Yes but it will need to be bleacheed first - when will the roots begin to show and when they do how often will i have to get them 'touched-up'?
Hair grows about an inch a month. So you will need your roots doing every 3 to 4 weeks if you wnat to keep it top-notch. - is it expensive?
At the salon, yes. At home, no. But at the salon your paying for high quality colour and a proffessional (I could be a little biased :wink:). Plus remember your going to be paying for more every month or so.
My suggestion is go to town and buy a semi-pernament colour that will wash out within about 10 or so washes. This will give you the oppertunity to see if you like it or not. If you do, then get it done in a pernament colour at the salon.
Salon will be much more likely to have the exact shade you like than the highstreet.
Show as a pic if once you've done it, I love wild colours :smile:
