    Not what I was hoping for

    I liked the smell of this. To me it had a tea tree like smell to it. I wanted to love it because of the clean ingredients. I didn’t get to use it long enough to see if it works for the thinning. The shampoo left my hair very waxy/dirty/greasy feeling. My hair lacked the luster and softness and clean feeling that other shampoos give me. I shower at night and would wake up looking like my hair hadn’t been washed for days.

    Not great

    Left my hair pretty greasy and stringy, might work for someone with dry hair but didn't work for me. It smells strongly of rosemary which is nice but may not be for everyone.

    Postpartum moms, this ones for you!

    So 12 months PP and my hair started falling out. Now 16 months PP and it’s coming out in clumps, I’ve lost so so much hair. I’ve been using this for about two months and while it hasn’t stopped the hair from falling out (thank you hormones), it HAS helped new hair start growing pretty fast. I can’t go without this stuff!

    Loved using this with the conditioner and the serum. Noticed a lot less hair, breakage, and more hair growth. Very pleasant natural soft scent.

    Not because of the item but because the way it was packed…. Leaked everywhere. Get in store if you can.

    My new favorite shampoo

    [This review was collected as part of a promotion.] After having 2 kids, my hair starts to thin out and never feel fullness after washing my hair. I have tried all different shampoo from big brand to organic. Nothing make my hair feel like before have kids. Until I tried this once for almost a month. I only wash my hair every other days. The shampoo doesn't create a lot of bubbles feel like others, rosemary scented. My hair didn't fall out a tons. I can feel the fullness after drying out my hair. This one will be my go to from now on.

    Feels nice but no difference noticed

    [This review was collected as part of a promotion.] I have been using it consistently for a couple of weeks. It has an earthy smell and lathers nicely. I havent noticed any changes in my hair. It doesn't feel thicker. But it proabably needs more time

    Honestly, amazing.

    [This review was collected as part of a promotion.] So I'm always usually pretty skeptical when I'm trying new things. I mean after all we don't know if it's going to work or not. I honestly am usually even more hesitant trying things on my hair just because I have very fine but thick native American hair. So it gets dry very quickly. I've been using this for the last week and honestly just truly amazing. My hair feels soft and it's very shiny and it feels even thicker than it did before. I am postpartum so I need a little help in that department with the postpartum shed happening. I appreciate very much giving me the sample and I truly will be buying this product in the future.

    Good, but not great.

    [This review was collected as part of a promotion.] First off, I'd like to thank California Naturals for the free product! I used the California Naturals Re:GRO anti-thinning shampoo for a couple weeks to give it a chance to see if it worked. As far as a more "natural" product, the shampoo worked surprisingly well at cleaning my hair. Often times, more natural shampoos leave my hair feeling oily and greasy, but this one left my hair feeling pretty clean. However, I noticed no difference in my shedding. The hair falling out while washing remained pretty consistant the entire time with no difference as to how my hair was prior to using. So it didn't necessarily do what the name implies which is why I give it 3 stars.

    [This review was collected as part of a promotion.] This shampoo leaves my hair feeling nice and clean. I like the way it lathers. The pump is very useful in the shower. Plus it smells amazing! It smells a lot like rosemary.

    Amazing!

    [This review was collected as part of a promotion.] I received the Re:GRO Anti-Thinning Shampoo for free through the BzzAgent program. I enjoyed getting to try this shampoo as I wanted to see if it would truly do what it said it would. I've noticed over the last few weeks of trying this shampoo that my scalp feels much better, especially during the cold winter months, my hair doesn't break as easily, and hair shedding has reduced. The scent is also a plus! I would definitely recommend this product to anyone looking for a clean, sulfate-free daily shampoo that supports scalp health.

    It's Fine

    [This review was collected as part of a promotion.] I really can't comment on whether the anti-thinning aspect of this shampoo is effective. It does a good job of getting my hair clean, but I don't love the scent, which is very herbal. It's something I'll definitely continue to use, and if I find that it helps to thicken up my hair or allows it to grow longer, I'd purchase it myself.

    Great product for hair loss

    [This review was collected as part of a promotion.] California Naturals sent me this free sample through the BzzAgent sampling program and I can honestly say this is a really great shampoo. I can't tell a huge difference if it made my hair thicker, I used it for 3-4 weeks, but I can tell a huge difference on my hair loss. This shampoo is the first shampoo that I have used in over 2 years that has helped a lot with hair loss.

    Gentle on hair and less shedding

    [This review was collected as part of a promotion.] I've been using the GRO anti-thinning shampoo for a few weeks now and I really like how gentle it feels on my hair and scalp. It cleans well without leaving my hair dry or stripped, and my hair feels softer and healthier after each wash. I've also noticed less shedding when I brush or shower. It has a light, pleasant scent and feels like a quality product—definitely a good option if you're dealing with thinning or fragile hair.

    Clean as a Whistle

    [This review was collected as part of a promotion.] I have very thin fine hair that gets greasy EXTREMELY easily, there are very few shampoos where I feel like I don't have to fully wash my hair every single day and I can still wear it down on the second day. This is one of the few that I don't have to shamefully hide my insanely greasy hair the next day. If you don't like essentials oils you probably won't love the smell, but it's really only strong while you are actually using it in the shower. I definitely will be re-purchasing!
