Should I cut my hair?

Context: I had severe bleach and extension damage a year ago and am trying very hard to regrow (oiling, K18, very little heat.) the top layer is much shorter, which is why the longer part is so thin and scarce. I really want my hair to look thick and healthy. Should I cut the bottom so it’s all closer in length? Thanks!!
