Trimming 

Although trimming may beautify hair by removing damaged or split ends, cutting does not promote faster growth. Nor does trimming remove all damage throughout the hair (remember, damage can occur anywhere in any length of hair depending on overall care it is given and various processes that are applied.) Trimming can help with tangles if one trims a slight amount off the ends of overall length when it's noticed that tangles seem to be more of a problem.
