Shampoo, conditioner, serum, wax, gel, hair spray, color... the list goes on. Hair, like the skin, is extremely absorbent and all those products can contain harmful chemicals.
Watch out for shampoos and conditioners containing petroleum products and sodium laurel sulphates; hair dyes with carcinogenic coal tar; hairsprays and hair gels containing petroleum derivatives, formaldehyde, phthalates, and synthetic fragrance.
Care for your hair and use only safe organic hair care products including pure organic shampoos and organic conditioners. And take the time to find out exactly what's in the products you're about to buy. Your hair, and health will love you for it.
