    Amazing

    My hair gal used this one day and I was hooked! She gave me what was left of her bottle and I ended up getting my own eventually. Best product ever! I’m always nervous not using conditioner but this leave repair hair mask does not disappoint!

    Fantastic product!

    This product is amazing! My hair was totally burnt from being over-processed with bleach at a hair salon! My hair was breaking off, felt like wet stringy cotton after washing, and was taking forever to dry! After using K18 as directed, my hair has been repaired, looks healthy, styles more easily, and feels great! Don’t hesitate to buy this product and save your hair ! It’s incredible !!! I love it!!
