Some of us were born with frizzy, uncontrollable hair. Others of us have dry hair because of all we put our hair through everyday. Either way, Kerastase Oleo-Relax Serum will give you amazing results. It is a lightweight leave-in serum you put in when your hair is damp, leaving your hair manageable, glossy and healthy-looking. It also protects your hair from heat styling, a must before you blow-dry or flat iron. Use this and your hair will look and feel fantastic. Not only that...this product smells amazing. $34. Shop here.
