Before I dried her hair, I put Garnier Fructise's Mousse in it to help make it not so soft after it was dried. Then I teased her hair just a bit with a comb right in the front to give it a little more volume & then pinned back:
Bring the rest into a low pony & don't pull the hair all the way thru (but don't pull too much - I just left as small a loop as I could). Secure that with another elastic so you don't have hair falling out of it.
The pony tail that is sticking out, begin pinning in loops about the same size & loop below.
Make it look as even as possible & use your fingers to spread the hair & hide any openings. That hair that is left over - you are going to wrap around the elastic to hide it. I spray it as I go, then secure it with a pin & it should stick good for you all day.
