If you have split ends you may need a trim. However, I had the same problem but didn't have split ends. I figured out I needed to do protein treatments.
I use 4tbsp. of plain greek yogurt, 2 tbsp. of olive oil. To mask the scent I also put about a tbsp or 2 of honey and a dash pf vanilla. Apply this focusing on your ends and leave it in your hair for 20-30 minutes making sure your hair is covered with a showercap. Then rinse out the yogurt mix with conditioner and this always helps my ends feel amazing.
I do this whenever I feel my hair needs it.
