Your hair is a great way to express who you are and, like the rest of your body, your hair is vulnerable to wear and tear, damage and dryness. A summer by the sea may be a wonderful holiday, but powerful UV rays as well as heavy exposure to salt and sand can damage your hair just as it can damage your skin. Colder seasons can also affect your hair, with dry air making your hair static and the cold giving it a flat appearance. Treat your hair well and it will radiate.
