Knotless braids
Box braids that begin with the wearer's own hair and add extensions gradually, with no knot at the root.
Knotless braids are a version of box braids that starts each braid with the wearer's own hair and feeds in extension hair a little at a time, instead of tying the extension on with a knot at the root. They lie flatter, move more freely and pull less on the scalp, so they are often more comfortable in the first days. They take longer to install. They became widespread from about 2019.
