I'm actually very impressed with this product. As someone who has long somewhat damaged hair but refuses to get a trim, I've tried many hair serums. I also don't blow dry / do anything to my hair on a daily basis (shower, brush, and go) so I'm always on the lookout for products I can quickly throw into my morning routine to help my hair out a bit. I grabbed this because I have some dry, split ends, and they're beginning to get pretty noticeable. It was $4, so I say why not, right? And I'm very glad I did! This serum can be put on damp or dry hair, and it works wonders. I usually do this right after showering on my damp hair, you just run it through your ends, then brush through to even out. As my hair dries it looks like all my ends are perfectly healthy and clean-cut. It's really awesome. I know they're not "fixed" as the bottle says (I'm pretty sure it's impossible to repair a split end haha) but it gives the illusion they are, and that's all I need. I'd recommend this for anyone who (like me) has splits and refuses to get a hair cut, or who wants a good light-weight finishing serum. When applied to dry hair this stuff gives a nice smooth, polished look, and it's not greasy or heavy.
