Anyone use the 'clip-in' hair extensions?I went for my hair trial today and we've decided I would like some clip ins (real human hair) to add some length to the back. Of course I've dyed my hair to be pretty coppery auburn so nothing matches them.If you have used them:1. What brand did you buy?2. Did you color / curl / style them?3. Would you buy them again?4. Where did you buy them?Thanks ladies!
