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...

Extended my wash days
Hair Type Wavy Hair
[I received this product in exchange for my honest review] This product has extended my wash days! The size make it's perfect for travel! Makes my hair feel refreshed without feeling heavy. Such an easy grab

Oily scalp must have
Hair Type Wavy Hair
[I received this product in exchange for my honest review] My scalp is loving this scalp serum! I feel like my hair and scalp have stayed less oily between washes since introducing it into my routine. My day 3 hair now looks like day 2 hair which is a huge improvement. I did notice a slight volume boost immediately after using it and blow drying my hair. There's no crazy scent and it doesn't leave any sticky or otherwise weird residue.
Waiting on Results
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Directions are super easy to follow. Very easy to apply and use. I like the applicator and the packaging. Doesn't leave my hair feeling greasy at all. I have used the product several times and I think I need to be more consistent with it cause I have yet to see any results.
Fresh and clean scalp between washes
Hair Type Wavy Hair
[I received this product in exchange for my honest review] It is an excellent serum to keep the scalp clean and fresh (stre) washed, it is easy to use it absorbs quickly and although at first I was not sure if it would work because its texture is thick and I thought it would leave my hair heavy or feeling dirty later, but it is not the opposite feels the scalp fresh, clean without oiliness. I'll buy this serum as soon as I run out of this pot I have.

It worked fine but was not life changing
Hair Type Wavy Hair
This scalp serum was super easy to use and I appreciated that it didn't have much of a scent. It wasn't too heavy and didn't make my hair greasy or overly oily. I noticed just a bit of a difference but no significant changes. I think my hair was a bit cleaner than usual in between washes but it was still oily and I still had to use just as much dry shampoo as usual. Honestly, I probably wouldn't purchase this item again.
