    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!

    I love this BRAND!

    What I appreciate about this brand is that it's not only clean ingredients but they actually work and leave my hair nice shiny, non tangle. I will continue to repurchase their products not just the shampoo and conditioner set.

    Heart eyes & soft Hair>>

    Sooooo… first & for most I am INFATUATED with Summer Fig Body Wash & Desperately Needed Super Moisture for my Bleached Hair. So it was a no brainer to get Summer Fig Super Moisture Shampoo & Conditioner… After about 2 orders in. I was curious about ReGro Anti Thinning because I still noticed a lot of breakage & frizziness still with Super Moisture & thought I’ll use ReGro at Home & Super Moisture at my boyfriends… The results on the days I showered at home were & are still so significant! Definitely what I was looking for. Although the scent isn’t as appealing as Super Moisture Summer Fig; the noticeable benefits are why I will continue to purchase. I air dry my hair because I’m always running late & on the go which probably explains why Super Moisture couldn’t tame my frizz all the way but Regro TAMES! & Has been helping my hair grow & is less of a hassle when brushing out. I absolutely am amazed & adore brushing my wet hair out with a COMB! I Would definitely recommend for 30 & up. My hair follicles are at its best. I’m so thankful to have given this Brand a try. Also pairing with the detangler they have. I love.

    Pleasantly surprised

    I am pleasantly surprised. I have been using the shampoo fir thinning hair along with the serum religiously for 2 weeks. I was skeptical but after two weeks it seems to be working. Less hair in the drain, and actual hair growth. 5 stars

    Noticeable difference

    I’ve been using this shampoo along with their curl conditioner for the last few months and have noticed a difference in both the fullness and length of my hair. Even my partner has made comments about my hair looking thicker, I love the smell and how the formula uses a more natural approach. Please never change it!

    Week One and Im Loving It!

    Within just a week of using this duo, I have noticed I no longer have a oily scalp on day 2 and more volume. I have fine hair, so it can seem dull. Im loving this combo.
