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. After loving the shampoo and detangling solution, I added this leave-in to my routine and instantly noticed an upgrad...

Very hydrating leave in tonic
Hair Type Wavy Hair
This Biolage hydrating leave in tonic makes hair feel soft and hydrated. First of all it gives hair a soft and smooth. It hydrates and conditions hair very well. It is really good and has good hair benefits. It has a creamy texture that makes hair fully hydrated. It has fresh and creamy scent. I recommend it and it is worth the money.

Good!
Great hair spray. I use it after washing with shampoo and hair conditioner from the same series. My hair looks very beautiful after using this treatment. I definitely recommend it.

Over-fragranced and didn't help
Hair Type Straight Hair
[I received this product in exchange for my honest review] For this leave-in tonic, I would prefer a pump that's easier to press down on, and this kind dispenses too much at once (and it's not in a fine mist). For me, the scent is way too strong! I don't think it dripped or leaked, but for some reason, my bathroom counter stank for days after the bottle was sitting on there. The ingredients are not ideal due to the several fragrance additives. Unfortunately, this tonic felt heavy on my hair and gave it a greasy look.

Love The Tonic, Hate The Sprayer
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] I Really Like This Daily Leave In Tonic! Firstly, It Smells Really Good, Secondly, It Does Hydrate Dry Strands And Makes The Hair Very Soft. My Only Con Is I Hate How The Sprayer Is; You Have To Spray A lot Of It Because It Doesn't Evenly Distribute The Product Like It Should. Other Than That I Love This Product.


Smells good!
Hair Type Wavy Hair
Something I didn't think I would like or end up using daily, but my hair is shinier, softer, and easier to manage after this addition. Wouldn't use if your hair was oily or not super dry as I could see it weighing things down/maybe making it look greasy.
