Comb and tie your hair
Assuming that you have already washed and conditioned your hair, you need to start by combing them all back and tying them into a high pony tail using an elastic hair band.
Make two sections
Now divide your pony tail into two equal sections, holding them separately as shown in the picture. Make sure the two sections are of equal length and thickness.
Start twisting the sections
Once you have two equal sections, start twisting them around each other evenly. Avoid very tight or closely packed twists and go for a uniform distance between every twist.
Twist till the very end
You need to keep twisting the two sections around each other till you reach the very end of your hair. Now keep holding the end firmly, making sure the twists don't loosen up.
Tie the end with a hair band
Now take another hair band and secure the end of your twisted sections to prevent them from unwinding as you style them further.
Wind the twisted length
Having secured the twisted section, you need to start winding it around itself (you can use two fingers to form the center) till a bun is created which touches the base of your hair at the back of your head.
You can adjust the height and angle of the bun to your liking before proceeding further.
Secure bun with bobby pin
After finalizing the position of your bun, secure it using a bobby pin. The pin needs to go through the center of the bun and into the base of your hair for a firm fit.
Alternatively, you can divide your pony tail (as shown in step 2) into four equal sections and then work on two different twists to create a larger bun with more strands.
In the end, use the hair spray on your bun to hold the style and you are all done.
