Don't use a company called 'Racoon'! They rip you off completely. I spent around �400 having extensions put in, and a further �12 for a bottle of special shampoo and another �12 for special conditoner. They continuously fell out, and I had to go back every 2 or 3 weeks and pay �40 to have the hair glued back in. Overall I think I had them in for about 3 months and they were the biggest waste of money of my life.
I now use clip-in hair extensions and think they're amazing. I wear 3 strips of hair that have clips on them to hold them to the scalp. They stay in all day, and I take them out to sleep at night. They don't damage the hair or pull it out and are much cheaper (my latest set were �40). They last for ever providing you look after them (they are real hair, so you get split ends and it can become dry). I wash them once or twice a week and that's all the care you need really. I'd recommend them to anyone.
Lots of places sell them now, so they'd be easier to come by. Please do not get glued in extensions!
Good luck!
