Not my favorite
I paired the Kristin Ess Hair Strengthening Conditioner with the matching shampoo and had mixed results. The packaging is really pretty and the scent is nice light and clean without being overpowering. It spreads easily through wet hair and rinses out well. That said, I expected a little more moistu...

Not sure about the smell
Hair Type Wavy Hair
[I received this product in exchange for my honest review] So to me it has this smell of celery. I don't know if it is just me or the one I received. I have used another Kristen Ess in the past and it didn't have that celery smell to it. It was a bit hard to get past the smell. After using it though my hair did feel nice and after styling it my hair didn't have a celery smell to it I do like the packaging, it is simple and the cap makes it easy to use.

Not for my hair type
Hair Type Straight Hair
This product didn't work well with my hair type. It made my hair feel more dry after using it and tangled easily. I felt my ends were splitting more after a few uses when paired with the shampoo. I have straight, highlighted hair that is normally smooth and healthy otherwise when using drug store products. It smells good, and a little goes a long way.
Pretty good!
Hair Type Wavy Hair
I think this product has good potential, my hair type may be too fine for this product. I felt that it was a bit heavy for me. It felt luxurious and smelled amazing. The price point is great. I think I may enjoy a different product from the Kristen ess hair line that is better for my hair type.
Could be more moisturizing.
Hair Type Wavy Hair
This smells good and does seem to make my hair feel stronger but I would prefer it to be more moisturizing. Overall it is ok but probably better for non chemically treated hair - though that is exactly the hair type that needs bond treatments.

Favorite conditioner
Hair Type Straight Hair
loved this conditioner ! It smells amazing, left my hair feeling so clean, and genuinely had my hair so smooth. As someone who is very picky with shampoos and conditioner due to how they make my hair feel and dry, I really enjoyed this! Definitely recommend!
