Super lightweight solution for all types of hair
Hair Type Wavy Hair
[I received this product in exchange for my honest review] The leave-in tonic is a great addition to your daily hair care routine. It's super lightweight, great smelling and leaves your hair feeling soft and healthy. It works as a detangler, heat protectant etc.
Decent Hydration Boost, but Could Use Tweaks
Hair Type Wavy Hair
(I received this product in exchange for my honest review). This tonic has its perks, but I wouldn't call it a must-have. It adds some nice hydration and helps smooth my hair out before heat styling, which I appreciate. It also helps with light detangling and doesn't leave buildup or stickiness. My biggest gripe is the sprayer—it comes out more like a fine mist, which sounds good in theory but makes it hard to apply evenly, especially to thicker sections. I wish the frizz control lasted longer throughout the day, too. On the plus side, it works fine on its own and doesn't require layering with other products from the line.

Amazing product!
