I have just returned from a vacation in in the south with lots of swimming and sunning. I came home with dry crusty but light and shiny hair. I was looking for a quick fix and this product delivered. I was going to leave it on overnight but ran out of time so I put it on my hair after washing it in the shower, toweled my hair dry, applied and left it on for an hour. I put a bag and hat on to aid the process. I rinsed it out and blew my hair dry and I couldn't believe how much it has recovered. It was not heavy and lifeless, it was soft and full of life. I was worried it would just be super flat and weighed down with oil. Not a chance! I would definitely use this product again. Well done Palmer, another great product in your product line.
