When I picked it up initially, I thought it was a regular wash out hair mask so I was a bit confused when I came home and figured out that it's a leave-in. I still wanted to give it a go anyway and it's actually better than I expected. It helps detangle my hair, ease frizz, and makes my hair look shiny and healthy. I don't know why it's called a mask though because it doesn't feel like one. It feels really lightweight like a typical leave in product. I also don't like that it's in a tub. I'd rather it in a pump bottle because I don't like having to use my hands to scoop out the product while I'm getting ready. It gets rather messy that way. Otherwise, a good product.
