Clarifying shampoos are a necessity for anyone who habitually uses styling products in the hair, even those we don't can reap serious benefits. The purpose of a clarifying shampoo is to cleanse the hair from residual product and oil build up that leave hair looking and feeling limp and lifeless. It's important to strip hair clean of any build up. After all, no one likes a dry and itchy scalp. Apple cider vinegar is an easy alternative but undesirable as it can be a stinky process. Fredrick Fekkai has the perfect clarifying shampoo that offers a heavy dose of apple cider vinegar but with yummy pear extracts that leave your hair squeaky clean and smelling delicious! I recommend using 1-2 times weekly. Work the shampoo into a lather rinse and don't skip the repeat, as this will insure ultimate results.
