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!!

Worked really well on my 4C hair

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.

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!

Less Breakage
I have baby fine hair and after using this shampoo for a month, I had to reorder.
The shampoo does make your hair feel fuller and I’ve notice less breakage.

Drying
Overall, it seems like a good product but as it was sent without the accompanying conditioner it was very drying to my hair even paired with other conditioners. I feel that would be much better to test it with the conditioner. It has a very strong, natural rosemary scent which I consider good because it is the active ingredient.

Radiant Regrowth Shampoo
I have noticed since having a baby at a later age, that my hair has thinned. My edges are sparse. Since I have started using this shampoo and seen my hair get a little fuller. It's not a ton but it has filled in more, especially around the edges. It has an a subtle scent that I prefer. I will definitely buy it in the future.

Great smell and my scalp loves it!
Shampoo cleans the scalp without feeling overly harsh. It removes oil and buildup effectively while leaving the hair feeling clean. The formula has a light, pleasant scent that is not overpowering. It rinses out easily and does not leave a heavy layer behind. After washing, the hair feels soft with a bit more volume at the roots. The shampoo is gentle enough for regular use and does not leave the scalp feeling dry or tight. While it is for thinning hair, noticeable improvements in hair thickness or growth require consistent long-term use.It works well as an everyday shampoo.

Results After 3 Uses
I bought this product last week and have used it 3 times since, alongside the Re:GRO Conditioner and the Re:GRO Hair Serum. I have already noticed close to a 50% decrease in my hair shedding during the shower. It is wonderful. Lovely rosemary scent and it leaves my hair super soft. I can’t wait to see how my hair starts coming in after another few weeks! Photo on the left is my hair fall before using the Re:Gro shampoo, conditioner, and serum. The right photo is after 3 uses:)

This shampoo was like any other
The smell is very strong and overpowering of rosemary. This scent is not a preference in shampoo, however, I did notice some baby hairs growing and my hair seems to be a little stronger. I could not use in my normal shower routine as the smell was not very pleasant.
