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.

Good product
Hair Type Wavy Hair
[I received this product in exchange for my honest review] [I received this product in exchange for my honest review] I've always enjoyed biolage products. The ONLY thing I really don't like about their products are the scents. They all smell relatively the same and I don't like the scent. These products definitely make the hair feel soft and moisturized. I didn't experience any fall out or allergic reactions. I have long hair and the bottle is lasting me quite a long time. I spray after I've towel dried my hair. The spray mists pretty evenly and it's easy to spray.
Perfect for damaged hair

[I received this product in exchange for my honest review]🔹Tonic: The unsung hero of the trio. It's like the conditioner's cool little sister who finishes the job. Just a few sprays on towel-dried hair and BAM—moisture locked in, frizz on mute, and that "I belong in a shampoo commercial" feeling activated.

I wanted to like this product but it didn't do my hair texture any justice (I have locs) but it did work on my daughters short pixie style hair [I received this product in exchange for my honest review]

Love it
I've been using this on damp hair after I shower and it makes my hair easier to brush through and helps avoid breakage. I'm no longer afraid to brush my hair when wet. I appreciate the spray nozzle as well. It does not have any overpowering smells. I received this product in exchange for my honest review.

Love It!
