Here is the thing, you want to grow it but you still need to cut it every 6 weeks!
I know what your thinking and if you maintain less being cut off then obviously it will still get longer, makes sense right?
What happens when you don’t remove split or damaged ends is that the split travels up the hairshaft and more is needed to be cut off. The frayed, Brocken ends make it look dry, out of shape and behave badly ( more than a 3 year old coming off a sugar high ).
Trim every 6 weeks, even if it’s half of what has grown or less, as your hair grows it will be healthy. Prevention is better than cure!
