Unfortunately I know all too well that getting bright colours back out of your hair is far, far more difficult than putting it in. Also, for some people, it is not an option to have brightly coloured streaks as it is not suitable for their workplace or other similar reasons.
Enter my solution - EXTENSIONS!
For those who don't use extensions, they may sound scary, but honestly they aren't. They are a brilliant way of adding thickness, length or colour to your hair with the added benefit of being able to remove them in minutes. I always go for clip-ins as bonds can be very expensive and also damage your real hair.
The key is to find extensions that are a very close match to your hair colour, I buy mine off eBay and pay around £25 for a full set in 18 inch length. The dye I used for mine (around £3.00, also eBay) is by Directions and the colour is 'Rubine'.
Anyway, this is how I achieved my summer hair-over...
I painted the tips of my hair extensions with the dye using a bleach brush, I then diluted some of the dye with conditioner and painted up towards the clips. Doing this makes the colour develop on a gradient, which I personally prefer.
With this particular dye you only need to leave it to develop for 20 minutes or so, then rinse the dye out completely and either leave to air-dry or use a hair dryer.
If you want your hair to look completely dip-dyed (rather than streaky like mine) be sure to buy hair extensions that are longer than your hair and they will create a block colour!
DON'T FORGET -
For streaks of colour you can buy pre-dyed clip-in streaks for around £3 each, check out eBay or Wig shops on your high street!
