I really like the concept of this line. The whole line is free of sulfates which initially led me to buy the EverStrong line. The EverStrong worked okay for me, but when I realized they had an EverSleek available, I was on off to the drugstore. I have fine hair, but lots of it, and in the winter it can get really unruly (read: frizzy) in the back. I am not sure if it is the lack of silicon, but this doesn’t weigh my hair down like other smoothing products. Argan, olive and sunflower oils are used to smooth. Without even blow-drying, my hair is smooth and bouncy. There isn’t much of a fragrance, which I like in a shampoo, but I’ll overlook it because this stuff really works.
