Just purchased this product, it doesn’t work on my hair type ( despite being reassured by Merwave via email) I’ve been a slave to serums and straightener and I believed (by their amazing advertising) that this was the product that was going to save me from my routine. My dry coarse hair looked even drier, horrible and scarecrow-ish and I couldn’t even run my fingers through it. I complained, got a generic reply, then ignored. They will not offer any compensation or refund so it’s just tough. I could get the same results from a supermarket mouse. Please do not waste your money or time on this mediocre product unless you have beautiful mermaid hair to start with.
