Hair Chalks - The Body Shop £5
The Hair Chalks from The Body Shop are pretty new releases. Available in blue and pink (I've got the blue one, as my Boyfriend's Mam gave me it to try out) these wash out shades are great to add a pop of colour to your hair in a really quick, easy way.
In terms of washing it out, it was really easy and just one shampoo and I was back to blonde. Just make sure you rinse the shower/bath afterwards or you might have a little bit of a blue tinged white!
I didn't find I had too much fall out on my clothes, but I was wearing a dark shirt just in case. To be safe, I would suggest putting an old towel under your hair and you could even wear gloves if you didn't want to get chalky hands or use the cotton pads.
I really like how bright the blue is, obviously the intensity of it will depend on your hair colour, but if you've got dip dyed hair, it's definitely worth trying out. I'd even like to try mixing the blue and pink together, possibly creating some lilac shade? It's been a while since I last mixed paint so my colour predictions might be a bit off...
Have you tried any hair chalks? What did you think?
