Can anyone give me advice on the best hair product there is to help prevent split ends. I've tried so many, and have not really found one that did much for me. My hair is so slow growing, and I finally got them to the length I almost want them. Having to cut the split ends monthly really is frustrating as it sets me back to the same length for a long time, I have to skip months of trimming to be able to get any gain.

Thank you!
