Recommend for dry hair! Best trio for the best hair.

No More Tangles!
To be honest, this isn't always needed if you use their shampoo and conditioner! However this is great to get those pesky knots out that you may have still post shower or in between hair washing days. It leaves your hair frizz free and super soft! I would highly recommend!

Excellent!
Hair Type Straight Hair
This has worked exactly how it's supposed to with hydrating and detangling. I love having this product. My hair gets oily easily so it's hard to use certain products. This one hasn't been an issue at all with oil. It works perfectly! [I received this product in exchange for my honest review]
Frizz free!
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] I would buy this product again and again. I love the way it reduced the frizz of my curly hair. It made my hair so soft and easily manageable. Not to mention the smell was great! 10/10 would recommend to everyone!
Amazing value!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Love this line of products! I would definitely recommend pairing the shampoo, detangling solution, and leave-in tonic. Makes your hair smooth and shiny, and has a great scent to it.

Silicone Tonic
Hair Type Wavy Hair
I received this product in exchange for my honest review. A leave in conditioner spray sounded like a great idea but it fell short. The sprayer could be inconsistent making the application not as seamless as it should've been. I wasn't impressed with the way it left my hair feeling or that my hair would get greasy and flaky within 24 hours. Realizing it contained silicone gave me clarification to the issues I was experiencing. I discontinued use and would not recommend.
