The peacock twist is a variant of a french twist where the ends are allowed to hang out rather than being tucked under. It looks very different on long and short hair – on shorter hair, it creates a fan-like affect, which is very fun, whereas on longer hair it just makes a shortened ponytail type thing, as you can see in the picture.
I used a comb to secure mine, but I really need to find something else – the hair was too heavy, and so it was slightly painful. Spin pins might be a good alternative.
1) Gather hair into a low ponytail. Do not secure.
2) Hold the ponytail so the end is up, and twist it most of the way to the end.
3) Use a comb, bobby pins, a fork, etc, to secure the bottom four or five inches of the twist.
4) Let the ends flop down.
