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...

Great scalp serum
[I received this product in exchange for my honest review] I thought this scalp serum was a nice addition to my scalp care routine. I have extremely fine hair that turns very greasy, sometimes in less than 24 hours, and this serum when added after a shower, is really helpful in elongating how much time I can go between washes, and overall makes my hair look much nicer after continuous use.
Love at first smell
[I received this product in exchange for my honest review] Smells amazing. Light weight. Doesn't make feel greasy. Doesn't make your hair look oily. Love the packaging, makes the product easy to place and use.
Refreshed babe!
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] Scalp Sync has its traditional Biolage amazing scent. The dropper is easy to use for dispensing on to scalp. As someone who washes my hair every other day this help reduce oil build up nicely. Felt like this gave a nice refreshing feel after use.

Not for me
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I don't think this product made that much of a difference. If anything I noticed that my hair was more likely to become greasy and I had to wash my hair more frequently.
Wasn't for me
Hair Type Wavy Hair
This product wasn't it for me. I used it consistently and did not notice results. It left my scalp feeling greasier than normal and I had to wash my hair more often. If product wasn't worked in, it deposited heavy in the scalp. I will not be reaching for this product again.
