Fishtail braids look so intricate, beautiful, and difficult, but I’ll let you in on a little secret; they’re one of the easiest braids to do. All a fishtail braid is: 2 pieces of hair criss-crossing back and forth over each other until you run out of hair. Here’s how you do it.
Step 1) Grab 2 Sections
Make sure your two sections of hair are about the same thickness. This will give you an even fishtail braid. In the image here, the left section is blue/purple and the right section is bright pink. These colors/sections will blend together as you complete the fishtail braid.
Step 2) Criss Cross, Right to Left
Take a small piece of hair from the outside of the right section (pink) of hair and cross it over to the left section (blue/purple) and place it on the inside of the left section of hair. Now do this same with the left section of hair. Take a small piece of hair from the outside of the left section of hair and cross it over and place it on the inside of the right section of hair.
Step 3) Cross Left to Right & Repeat
Continue crisscrossing back and forth all the way down until you right out of hair.
Final Tip: If you take too much hair to cross over it will turn into a 3 strand braid. You always want to only take about half of the section, leaving half behind to maintain the fishtail braided look. Ensure that after crossing that you have only 2 distinct sections that are about the same size.
