What's the best splint end sealer product to use?

Alright, so I have a few split ends. I just got a haircut but i still noticed some split ends and my mom won't make me another appointment. In all these magazines I've seen a ton of splint end sealers that help with splint ends. I'm not sure which one is best! I really don't want to waste my time or money, and I would just like to at least help my splint end problem! Thank you for helping! <3<3<3<3
