Recommend for dry hair! Best trio for the best hair.
I received this product in exchange for my honest review. The Biolage HydraSource Daily Leave-In Tonic is the final step in my HydraSource hair care trio, and it's the cherry on top.

New Love
Hair Type Straight Hair
[I received this product in exchange for my honest review] I just had to share my love for the Biolage Hydra Source Leave-In Tonic! This product has transformed my hair care routine. It not only detangles beautifully but adds a burst of hydration that my dry hair desperately needed. The mist is lightweight and non-greasy, which is fantastic for everyday use. I love how it leaves my hair feeling fresh and looking shiny without any build-up. Plus, the subtle scent is a lovely bonus! If you're looking for a leave-in that hydrates and protects, this is a must-have. Highly recommend!
Adding this to my hair routine
Hair Type Wavy Hair
To be honest I've barely used leave in conditioner or tonic before. My hair is dry and somewhat dull. I've therefore been using hair mask to mitigate the problem. Recently I learned that these leave in products can make a difference especially when they are applied at blow dry and can protect against heat. I gave this a shot and I do feel my hair looks healthier and feels the tangling problem is much better. I'm adding this to my hair routine so the hair can stay this way longer haha.

Good
Hair Type Straight Hair
My experience with these products has been very good. In this case, I'll talk about the leave-in tonic. To be honest, whether I use it or not, I don't feel it makes much difference to my hair. The product is good, it detangles very easily and helps to make the hair softer, but I suffer a lot from oily hair and when I use it, it's because I want a smoother look without volume.
Would repurchase

[I received this product in exchange for my honest review] I used this is combination with the shampoo and detangling solution. It works really well and doesn't smell bad. It works really well on my daughter's hair. Her hair tangles so easily and this makes things so much better
