    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.

    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!

    Amazing conditioner

    I've been using this anti-thinning conditioner for a few weeks now, and I'm honestly impressed with the results so far. My hair tends to shed a lot, especially when detangling, but I've noticed significantly less breakage since adding this to my routine. It leaves my hair feeling soft, hydrated, and much easier to manage without weighing it down. One thing I really like is that it doesn't make my scalp feel greasy or heavy, which is something I've struggled with when trying other "thickening" products. My hair also looks a bit fuller and healthier overall, which gives me more confidence when styling. The only downside is that it takes consistent use to really see results, so you have to be patient. But if you're dealing with thinning or shedding and want something that supports healthier hair over time, this is definitely worth trying.

    I like the scent of the shampoo and conditioer but feel it dries my hair out. Not sure I can use this long term for my hair loss issues. I already have dry hair to begin with. This probably wont be a issue for someone with normal hair.
