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 hair drank them up!!

first time trying the California Naturals Super Moisture shampoo and conditioner. I’ve loved the body wash all summer and these are just as good. My hair drank them up!! I noticed a difference in the manageability and bounce, love the INCIs and the earthy fruity scent that’s so unique. Also these are SUPER affordable!!

These California Naturals products smell so good and worked really well on my 4C hair, which is not always the case when I try new hair products. Felt really soft after using these. Safe to say it works for all hair types and it’s super affordable.

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.

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!!!

Ruined my hair
After using this once it made my hair so dry that it tangled as soon as I finished washing my hair. I had to get my hair cut to get the tangle out. So the product is not worth it when I had to spend over $100 to fix the issue that this product caused. If I could return it I would.

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.

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.
