    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.

    Disappointing

    My main gripe is that I didn't notice much difference in hair that came out when I showed/brushed my hair. I noticed a bit of a difference in the last day after using for a couple weeks. However because you put the conditioner all over your hair, including the crown, it has made my hair much greasy and needing to wash it more often than I like. So I don't know if the small change in hair loss if because of the benefits of the conditioner or because I'm washing it more often. I'm also not a fan of the texture of the conditioner since it doesn't spread well through my hair.

    Really love this conditioner!

    As a girlie who has low iron I've really loved this conditioner! Great scent, great for fine hair, and I have truly noticed a difference in hairloss/thinning hair. Leaves my hair feeling nourished and has seemingly helped prevent some of my shedding!!!

    Softer and more full-bodied hair

    I used it after shampooing, applying it from medium to tips and letting it act for about 3 minutes before rinsing. From the first use I noticed my hair much softer, hydrated and easy to untan. I loved its fresh rosemary aroma and that it doesn't leave a heavy feeling. With continuous use, my hair feels stronger and with less breakage. In addition, I like that it does not contain sulfates, parabens or silicones.
