Wasn't any better or worse
[I received this product in exchange for my honest review] I have very oily hair and I really am at the point where I'm getting desperate to figure out what's going on. I've tried so many products aimed at oily hair and not very many products have been successful. I would say this Biolage Scalp Sync...

[I received this product in exchange for my honest review] This is a great scalp hair serum! Works great and has a nice hydrating feeling without making my hair greasy! Doesn't leave a residue either! I highly recommend giving it a try!

Must try

First trying this scalp serum. The texture is pretty thick and smells amazing but it absorbs really well. My hair does not get oily that quickly. A little goes a long way✨

Didn't work well for me
Hair Type Straight Hair
I received this product in exchange for my honest review. Biolage Scalp Sync Oil Balancing Serum is a serum you put on your scalp to help control oil. I tried this out several times but I only noticed done results. I still would have needed to use dry shampoo or wash my hair. There was some reduction in oil though. I found the serum to be lightweight and it absorbed into my scalp easily. No residue.

Clean scalp = better hair days!

[I received this product in exchange for my honest review] I've been using this Serum and I actually loves how lightweight it feels. It helps control oil between washes without making my hair feel dry or heavy. As a busy mom. I don't wash my hair every day, so this has been perfect to keep my scalp feeling fresh and clean longer. Plus, it's super gentle and doesn't irritate my scalp.
Can't believe it worked
Hair Type Straight Hair
[I received this product in exchange for my honest review] I was fairly empressed with this product. It wasn't life changing so I only gave 3 stars. I did notice a difference in the oiliness of my hair in between washes. But to be fair I have very oily hair. I loved that I couldn't tell I just put a serum on my scalp and it didn't change my hair texture.
