As we did for a how to guide to another 2011 hair trend, braided top knot, we enlisted the help of an expert on all things hair, Melbourne stylist Annika, and paired her with Scene Models' Taylah Verney for the following how to guide.

Ensure that your hair has enough texture for the hairstyle to hold.

You're not looking for so much texture that this becomes a messy hairstyle, but just enough that it adds volume.

With Taylah's hair a spray-in mousse was applied to her hair's roots. It was then worked through with a hair dryer.

If you have flat or fine hair simply apply more mousse. This is a hairstyle that will benefit from liberal lashings of mousse, so be worried more about underusing it as opposed to overusing it.

If the mixture of hair dryer and mousse results in too much of a messy effect (perhaps natural waves dominate the hair, as pictured) brush out the excessive texture.

The end result should be as such.

Using a comb divide the hair at the back down the centre hair line, beginning at the crown of the head and finishing at the nape of the neck.

Hold both sections of the hair part separately ensuring that you're holding all strands of hair in your hands.

Tie a single knot in much the same way you'd tie any knot.

To do this place one section of your parted hair over the other, loop that section though the created hole and pull the two parts tights.

Step four has given you a single hair knot, but this how to is for a double hair knot. So, to achieve that style simply repeat step 4 by again tying another knot.

To achieve this use the two ends of your hair part created in step four and tie another knot layered on top of the previous one.

Slightly twist for affect. Then put a bobby pin through the right hair part and the hair knot.

Secure the knot by placing a bobby pin through the left hair part and the hair knot.

You may also opt to use a third bobby pin that goes through the second knot created.

Finish with hair spray to hold any short hairs in place.
