After just one wash with Breck, you will notice a very clear difference! When I started using it, my hair started looking a good deal straighter, and as I have naturally wavy hair, that tends to be a hard feat without a straightener and blow-dryer. It also helps with hair loss and repairs hair. It honestly leaves your hair amazing! Soft, radiant, shiny, and best of all HEALTHY! Give it a try! You will love it too!
