You should keep in mind basics of braiding, which are as follows -

Go for a deep-conditioning before braiding. Have your hair properly trimmed, if you wish to have a stylish braid. Prefer to apply lightweight leave-in conditioners. Immediate braiding of a chemically straightened hair may harm it. Go for braiding only when a professional thinks it is safe for your hair to bear tension of braids. If you wish to use human-hair extensions, choose ones that are lightweight with microthin wefts. When you wish to match extensions to your own hair color, opt for one that matches middle or end of your hair. If you match extension with root color of hair, extension would look darker than actual hair as root hair always have a darker look. If you go to sleep with wet hair, you are sure to invite unruly tangled hair. As right braid can form only with perfect hair, be careful while maintaining them.
