    Contact dermatitis sufferers dream

    These 3 are completely allergen free for me, which is pretty amazing considering the amount of contact allergies I was recently diagnosed with. A lot of the fragrance free shampoos I had tried really weighed my fine hair down. This one does not, but it also isn’t overly drying either. Super happy with this bundle

    Frizzy hair

    This product has left my hair so much more manageable. My hair doesn’t feel weighed down anymore, but the frizz is more controlled.

    The scalp duo unscented

    My skin had been breaking out in hives around my face and jawline and I thought the culprit could be the scents in my drug store hair products so I switched to the unscented scalp duo and have had fewer itchy spots on my face! I think my hair looks better too but I really tried it for skin reactions, so I am happy to say those have decreased.
