    Great growth serum for color treated hair! All natural!!

    I always am weary of introducing new hair products since i dye my hair, but I do have breakage from the bleach. This serum is great! I use it when I do my slick backs, but it's not too sticky so you could use it on your cleaner hair days. I haven't seen too much growth yet as it's only been a few weeks, but I will continue to use it since it's so simple! I also have a friend who just finished chemo, and she's looking for clean products. Since this is all natural, she's also giving it a try!

    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.

    Changed my hairline!!!

    I've struggled with hair thinning & loss around my hairline, and using this a few times per week has completely changed the game for my hair growth around my hairline. It's thicker, and I've seen re-growth even in the bald spots! Having something affordable and effective is SO hard to find and this actually worked. Be sure to keep up with it and you will see results!

    My Go-To Shampoo

    This has become my go-to shampoo! Not only does it smell amazing but it actually delivers on what it says it does...I have not had that much hair fall/ shedding since using this product ( a little over a month), my hair strands feel stronger and most importantly for me, my hair has more volume. Overall, my hair appears healthier (shiny, no frizz, volume). Highly recommend!
