I have used this ponytail trick on several occasions for my work. When I fell across it on makeup.com, I decided to share it with you all.
Just be sure you get as much volume into your own hair as possible. Try drying hair upside down to help create the volume , and then it is good to add a touch of wave to your hair which also adds extra volume. This idea needs to have full hair to hide the trick.
The photos are pretty explanative and so easy to follow. Have fun.
