Make a Perfect Synchro Bun Brush the hair into a ponytail just above the ears. Twist the pony tail. Wrap the hair round the centre into a bun (if the hair is very thin or short use a bun ring to make the bun). Pin the hair. Add a hair net and pin again. 1. Make up the gelatine as per the instructions but only use ½ the quantity of hot water. Most swimmers need 1-2 sachets of gelatine to properly hold the hair in place. It should be the consistency of a thick sauce or like glue If the gel is too thin it will run down the girl’s necks which cause quite a mess and dry gel on the neck which is very uncomfortable. 2. Wrap the towel around neck and paint the gel all around the head and bun. Pay extra attention to the sides, front of the head (fringe) and the base of the head (top of the neckline). If gel runs down the neck the easiest way to remove it is to wipe it with the damp towel. 3. The gelatine will wash out with shampoo.
