    Great for Postpartum Hair Loss

    I'm 5 months postpartum and have had a lot of hair loss but since using this product I've noticed a lot less shedding! Also seems to be very natural ingredients and I do enjoy the scent and color it's very earthy but might be too much for some people.

    The best conditioner

    One of the best I've ever tried. I like how it's made with natural ingredients and it helps prevent thinning hair. The smell is really nice and not overpowering.

    It’s nice

    I have only used the product twice so i can’t really say much about it yet. However I like the scent and how soft my hair feels afterwards.

    I Love This Natural Conditioner!

    I have very thin, lifeless hair. I feel I've seen a difference in my hair using this conditioner. I have more volume and a fuller feeling after it dries. I'd purchase again!
