Trimming is necessary to remove split ends and knots that cannot be unravelled. It can also be used to help maintain the ends aesthetically, where older, weathered ends are cut allowing the hair to look fuller/thicker.
The method you select to trim your hair depends on three main factors
1.The length of your hair
2. The extent of damage to your hair
3. How much hair length you are willing to lose.
The key tool that you require is a sharp pair of scissors. Hair scissors are useful because well made shears have a very sharp edge allowing for a clean cut without fraying. Depending on the method you choose, you may optionally require a mirror and a source of bright light. Here are the three methods
1. Search and Destroy
This method should be selected if you want to cut off as little hair as possible as only damaged hair is selected for cutting. The method is simply to take a small section of hair (approximately 1 square inch) and search the ends for any splits, breaks, frays or knots. Ideally the cut should be performed at least one quarter inch away from the knot/split/fray. This will ensure that all the damaged portion is cut. The search and destroy method can be performed as frequently as you like, however, if you need to perform this method more frequently than once a month, then your hair may require or suit a more aggressive trim (see method 2 and 3).
The key advantage is that you retain all healthy hair but the disadvantage is that you can end up with uneven lengths (though if you mostly wear your hair in curly/textured form this may not be an issue).
Notes: If you are doing this method on your own, your hair has to be sufficiently long for you to see the hair ends. This is more important for hair in the middle and back of your head which needs to be pulled forward to be seen. You can use a mirror to aid you or you can ask for help from someone you trust to help if your hair is not long enough.
