Chances are our dyes hair would be permanent, but wouldn't it be a waste to dye it back when school starts? Here's where hair chalks come in handy if you want a day's of hair colour. Use artist pastel's chalk, which is actually chalk, not oil pastels. It's easy to get them at any art store around your area.
You can have them in a single shade, like this:
Or layer them,
Or even jumble them up:
It's so convenient to use it, just rub the chalk on till it sticks, that's all. I expect to see some chalk dyed hair on the streets pretty soon, though.
The pros:
1.It's convenient and cheap.
2.It can be removed at the end of the day.
3.Can be used to experiment before deciding on a particular colour which looks good on your hair.
4.Comes in a variety of bright, neon like colours.
The cons:
1. It's not permanent.
2. If isn't done well, it can be disastrous looking.
3. It doesn't come in natural looking colours like auburn or chestnut.
Anyway, for the die hard fashionistas plodding about, hair chalk is this summer's IN thing, so my suggestion is go get them whenever you can.
Warning: for teenagers and daring YA only, unless you want to end up like a fashion f aux pas..
