Here are some easy and quick braiding styles.
Make three hair sections and weave them one after the other.
Similar to classic trinity, but you start from the crown instead.
Make two sections and further divide each into smaller strands.
Make three sections and braid it in reverse to the classic trinity.
Section hair into three near the hairline and begin braiding, but leave the middle strand loose.
Separate two sections from the nape and make tiny braids, and wrap around your loose hair.
Pomades will help you keep them in place.
