I had my hair cut and highlighted last week as usual when my hairdresser suggested I might benefit from hair extensions - saying that many women with thin hair feel more confident with them in. Until that point I hadn't felt a lack of confidence about my hair!! Now I'm considering it but for every positive thing I read about extensions, there's a horror story of people's hair falling out or being damaged beyond repair. My hairdresser has suggested nano bead extensions - can anyone give me the benefit of their experience?
