What is a fishtail braid? Well instead of a standard French braid, which normally starts near the hairline, you start the fishtail french braid a little further back.
Total Beauty have a step by step guide on how to make a fishtail braid. To begin, gather your hair into a ponytail at the nape of your neck. Use a throwaway elastic — one that you can snip away with scissors at the end. Next, split your ponytail evenly into two sections. Unlike the classic plait, a fishtail braid only requires two sections.Use your finger to separate a small section of your hair from the outer edge near the elastic and cross it over to the opposite side (overlapping just like you would if you were doing a standard braid). Re-grip your hair to tighten plait, still holding two sections. Continue overlapping pieces from both sides of your ponytail, all the way down to your ends. Be sure to pull small sections from underneath to cross over, and try to grab the same size (about a half inch) sections from each side. Once you’ve woven your hair down to the ends, secure the fishtail braid with another elastic. Then, use scissors to carefully cut out the elastic at the base of your ponytail. Finish your fishtail braid by gently tugging on your braid with your fingers to loosen it for an effortless look.
