To make a fuller ponytail, use a clip or two bobby pins on the elastic band, make sure the hair covers it, and this will make your ponytail look fuller!
To add even more volume, tease the tops a little and use hairspray to hold it!
Want a longer looking ponytail? Split your hair into two (or three) sections, keeping more in the top section. Put the ponytail at the top where you want the highest part to be, use the smaller ponytail underneath ensuring the hair from the top covers the band!
This makes your pony longer!
Leave a small section of hair from each side out, then put your hair in a low ponytail. Using the two pieces from the side, cross them over and tie them through one another - securing with a bobby pin.
This look is simple but adds a little variation to your ponytail.
A very simple and fast trick. Split your hair at your crown and put the rest up in a ponytail. Going back to the remaining hair, tease gently, pin back to create a bouffant or quiff and secure with hairspray. Ensure that the ponytail is covered.
Feeling daring? Bring your ponytail through!
This is probably the simplest of them all. Tease the front of your hair, and style it however you wish (or simply put it back with the rest of the ponytail). Once the front is done, put the rest of your hair in a ponytail and tease it all - focus more on the top for the messy volume look.
