I bought a half wig by hairdo for £75. I chose this brand as they boasted it being 100% human hair and i wanted to dye them pink. ( like in my profile picture)
i put the dye in , 50% pretty flamingo and 50% hot hot pink by manic panic, and wrapped them in aluminium foil overnight. when i washed them out the next morning most of the hair was still blonde and the parts that had dyed were very pale pink/purple.
So be careful when buying their extensions if you want to dye them. I have written to complain several times and they wont acknowledge my emails.
