My stylist told me that I should trim my hair about every six weeks, but how can I retain length and get longer hair if I trim my hair every six weeks?
Exactly. Don't do it unless your hair is damaged on the ends. If you want to maintain your hair at a certain length, then yeah, this would be the way to go. If you are trimming your hair as fast as it grows, then all you are doing is breaking even.
Do any of the ladies here trim on this type of timeframe?
Nope. I haven't trimmed my hair since September. Don't plan on doing it anytime soon either, I don't need to. Only trim your hair when you need to.
when do you know it's time for a trim? how do you trim and grow longer hair at the same time?
I know it is time to trim when my hair is damaged on the ends, if my ends feel really hard, or if my hair starts to really stick together on the ends (tangling very abnormally). Also if the ends of my twists are really frizzy no matter how much product I use.
You can trim and grow long hair at the same time, you just can't trim your hair off like a mad women and still expect to grow long hair. You have to preserve your hair, treat it well and minimize damage so that you will not have to trim as often. If you are constantly damaging your hair, then you will have to trim more often. If you are doing a good job of keeping your hair healthy, then it will not be necessary to trim as often.
