The MilkShake line by z.one Concepts is a wonderful product line- it is pricey but worth every penny. It can only be purchased in salons. The Glistening Treatment is one of the products in this line that is exactly what it says it is. It is highly conditioning and smoothing. Its an areosol spray that you apply to shampoo'd hair, comb thru and leave for several mintues before rinsing. You can feel the difference in your hair instantly. Its wonderful for extremely course frizzy hair. Can be used several times a week or as needed. It contains Date seed extract, Abyssainian oils silicone to help smooth down the fizzies. It leaves your hair wonderfully soft and silky. I would not recommend this product for fine hair.. Its extremely moisturizing, and almost heavy to the point if not rinsed well it would weigh down fine hair and give it a greasy look.
