Micro braids are miniature braids that result from braiding natural hair with hair from extensions. Thin or damaged hair is not recommended for this hairstyle, according to All-Hair-Info.com. Waiting two weeks after receiving a relaxer treatment and moisturizing the hair before receiving micro braids are also recommended. The end of a micro braid needs a knot to prevent the micro braid from unraveling.
Hold the braid at the end between your pointer finger and your thumb.
Separate a long, thin strand of the hair at the base of the braid from the rest of the loose hair. Wrap the hair around one of your fingers to form a loop underneath the braid.
Wrap the loose hair around the front and place the ends of the loose hair through the loop to form a knot underneath the braid. Tug on the hair gently to secure the knot.
