Start with clean, dry hair; brush out tangles
Part hair into three sections at the top of your head (left, middle, right)
Cross the left section under the middle section
Cross the right section under the new middle section
Continue braiding by adding hair to each outer section before crossing under
Add a small section of hair to the left outer section, then cross it under the middle
Add a small section of hair to the right outer section, then cross it under the middle
Repeat: left under, right under, adding hair each time
Keep tension consistent and pull evenly
When you reach the nape (or run out of hair to add), braid the remaining three sections normally (under-under pattern)
Secure the end with an elastic band
Gently tug the braid edges outward for a fuller look, if desired
Optional: mist lightly with hairspray to help hold the style
