Split end ender :)

It is pricey, but there is nothing better than this for split ends.

Obsessed

It definitely has a learning curve and you might need to use more than indicated on the bottle. I was so disappointed at first but my hairdresser used it on me and I became obsessed. It’s so easy and fast compared to my 20-30 min mask. I sometimes don’t even use a leave in conditioner after.
