Cornrows are the foundation technique behind most protective styles — Fulani braids, feed-in ponytails and braided updos all start from the same flat, underhand cornrow.
Learning the basic straight-back row first, before attempting a curved or geometric part, is the fastest way to build the muscle memory for tension and feed-in speed that every other cornrow style builds on.
Even tension matters more than speed for a first attempt — a slightly loose cornrow can be fixed by redoing one row, but pulling too tight across the whole head can cause real scalp irritation.
Save this tutorial for later — pin it to your braids board.
Detangle the hair fully, then part off a straight row from the hairline to the nape using the rat-tail comb — a straight, even part is what keeps the finished row looking clean.
Take a small section at the front of the part and split it into three strands. Cross the outer strands underneath the middle strand (not over) — this is the underhand technique that makes the braid sit flat.
With each crossover, pick up a small new section of hair from along the part and add it into the strand before crossing, keeping tension even so the row stays flat against the scalp.
Once you reach the nape and there's no more hair to feed in, continue a regular three-strand braid to the ends and secure with a small elastic.
Repeat for each row, then smooth the front hairline with a small amount of edge control and a soft-bristle brush.
Crossing the strands underneath rather than over — that "underhand" motion is the entire difference between a flat cornrow and a raised braid, and it takes practice to get consistent on your own head.
Yes, though straight hair has less natural grip, so a small amount of gel or mousse at the root of each row helps the braid hold its shape through the day.
A handheld mirror angled against a wall mirror lets you see the back of your part while braiding — doing the first one or two rows slowly and checking often is faster in the long run than redoing a crooked row.
