Soooo good!!!!
[I received this product in exchange for my honest review] I could NOT contain my excitement when I found out that Biolage was adding another product to my favorite Biolage haircare line! I have used Biolage for 19 years now, I fell in love with their products the very first time I used them back in...

Better in time?
[I received this product in exchange for my honest review] My hair is super dry, so when I found out I was getting gifted this product to try out in exchange for my honest opinion I was thrilled. My hair could definitely use more moisture. I used this brand before and I do love most of their product...

Not greasy at all!
[I received this product in exchange for my honest review] This serum left my hair feeling extremely soft and hydrated. It absorbs well and does not leave your hair feeling greasy/oily. If you struggle with dry hair, i highly recommend adding this in to your post shower routine!

I like it
I'm seeing a difference in my scalp. I notice at night (which is usually the time i get dry and itchy scalp) i am having less itchiness. I like the consistency of the serum and the smell is nice.
Great
I received this item for free from Biolage in exchange for my honest opinion. I have very fine hair that is on the thin side, so I'm hesitant about what I put in my hair and on my scalp so I don't end up looking like a drowned rat. When used sparingly, it didn't make my hair look or feel greasy!
Great multitasking hair serum
[I received this product in exchange for my honest review] Talk about a multitasker ! This scalp and hair serum is amazing !! I've had an issue with dry scalp for years , and this has really helped ! The application is simple !



A silky, lightweight hydration booster with a gorgeous clean
I am loving this Biolage Hydra Source Moisture Method Scalp & Hair Serum! The texture is wonderful—it feels very silky, and it hits that sweet spot of being not too thick but not too thin, making it super easy to apply without weighing my hair down or leaving any heavy residue. It also has a very clean, refreshing scent that makes the application feel like a spa moment. My hair feels so nourished and soft since I started using it!
