Hair Type Very Curly Hair
[I received this product in exchange for my honest review] Love this shampoo. It's a bit thick and my bottle leaks a little but other than that it's 10/10. It has a nice scent and my hair has actually felt softer and less frizzy since using it

[I received this product in exchange for my honest review] This Kristen Ess Hair Strengthening Shampoo is such a great quality shampoo. I love the pale pink color of the bottle and the convenient way it opens and closes. It smells absolutely amazing and it leaves your hair feeling so soft and smooth and even appears to have a lot more volume. Great value for your money. I highly recommend this product.

Hair Type Wavy Hair
I received this product in exchange for my honest review I've been testing this shampoo for a few washes now, and overall, I've had a positive experience. I'm currently dealing with hair shedding, so I'm very mindful of the products I use on my scalp. For reference, the first photo shows my hair before using the product, and the last photo shows my hair after using it. I like that this shampoo is sulfate-free and meant to be applied mainly on the roots. It cleanses my scalp well without feeling harsh or stripping. After washing, my hair feels clean but not dry. What I've noticed the most so far is the shine and the scent, my hair looks healthier and smells amazing after each wash. I also appreciate that it's infused with biotin and amino acids, which are formulated to help strengthen the hair and reduce breakage over time. I'm not expecting instant results, but after several uses, my hair feels softer, more manageable, and stronger-looking. I'll continue using it to see how it performs in the long run.
