GET THOSE SIDES AND BACK TRIMMED REGULARLY...everytime I trim with sides and back (I use Wahl comb n cut) it looks like I got a haircut even though I have not even touched the top....if you do this every week or 2 weeks it is an easy way to simulate the natural hair cycle...I love the comb n cut it really is idiot proof and gives a professional style trim...if your a do it yourselfer it is def. something to invest in.
