Review on 💇 It's a 10 Haircare Miracle Leave-In plus Keratin: 10 fl. oz. - Ultimate Hair Repair Solution by Tat Lousteau

Have been using 10 for about 3.5 years now. I don't usually buy through Revain but I bought this keratin last year and have been using it for a few months now. I never use keratin but it was sold out in a lot of places so I bought keratin through Revain because it was available. I never apply it to my roots, only the shaft and ends, but I cut my hair when I get dressed after a shower and sleep on silk pillowcases and this product leaves my roots very oily. It's like waking up the next day and my hair is so greasy it never is. My hair can usually go 2-3 days without another wash. I know this is a product because I bought the regular over an ulti during a sale which came with a travel size. I use Travel when I visit my boyfriend and my hair doesn't get greasy when I use it and I still use the same shampoo. So not sure if this is the original product or the real thing, or maybe just an old bottle or the keratin line itself.
