I had extremely short hair when i first had my extensions fitted. This is the 3rd refit of the same ones and they are still in tip top condition. They usually last 8-12 weeks. People are shocked when i say i have extensions as they look so natural. This is all because of Hannah at the manchester arndale store. She does an amazing job every time, she even curled them for me and my hair looked amazing at the races. Wouldn't go anywhere else.
