Step 1 Invest in a pair of hair cutting scissors. They are fairly cheap and available at Sally's and Walmart.
Step 2 Put your hair in 10-20 twists.
Step 3 Trim off the ends of each twist. OR
Step 4 If you have visibly defined curls, go curl by curl and trim the end.
Your hair does not have to be wet if you use these methods. If you wear your hair straight from time to time, it is best to straighten the hair first.
