I absolutely LOVE my Pro-tac extensions - they were easy to apply, feel very comfortable and I'm constantly getting compliments on how good my hair looks! I have fine hair but using Pro-tac from Unbeweavable has made my thick hair extensions totally undetectable. I've had them in for almost a month now and they still look brand new! I would highly recommend Pro-tac to anyone who is thinking about having hair extensions. Thanks Unbeweavable!
