    At long last! My hair is actually soft!

    I’ve always had "crunchy" hair when I let it air dry, but after using the HYDR-8 Leave-In Conditioner, my hair dries so much softer! The hydrating properties are clearly making a difference — my hair feels smoother and is noticeably less frizzy. I also love that this product does double duty: on days when I use heat styling tools, it acts as a heat protectant too. Highly recommend it for both hydration and protection!

    A little goes a long way

    Remember to follow instructions and shake it. It is so effective you can spray it on lightly and it makes hair soft with volume. Highly recommend!
