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.
