Trim Your Own Hair Between Haircuts

To maintain your split ends in between hair cuts, twist a section of hair between your fingers. You will notice that the dry and damage hairs stick out from the twisted section. Simply take some scissors and snip these off. As you let your hair unravel, you can see that the split ends diminish greatly. There is very little chance of ruining your hair cut as you're basically just thinning out the ends.
