Just obsessed
[I received this product in exchange for my honest review] This one made me fully obsessed. I started using the product the same time when I started other Redken products, so, I tried everything together. I will share my experience how I apply this serum: I add few drops of serum directly on my sc...

Confusing system— 2 products, same result
[I received this product in exchange for my honest review] I had a hard time differentiating the purpose between this spray and the other spray in the system, it just felt like an extra step. They both felt like the same texture and seemed to do the same thing. There weren't any instructions on thei...

Feels Nourishing
Hair Type Straight Hair
[I received this product in exchange for my honest review] This feels very light weight on my hair and scalp. I didn't feel like I needed to wash it out of my hair afterward either. I would assume like any product though, it would create buildup after multiple uses and a lack of clean hair.
Coats the Hair
This is an okay product. I will say that it coats the hair and makes the hair greasy. I'm not sure if it helps with breakage but it does spray out nice. It has good packaging. I will say that I can live without it.
Eh…just ok.
Hair Type Straight Hair
I bought this whole system to try due to my very thin/fine hair. I would say it definitely helps improve density of my hair. But in exchange, my hair feels very dry and stiff. Without the products in this system, my hair feels hydrated and is shiny and soft. Using this system makes my hair tangle easily and it doesn't glide thru my straightener anymore. I would also say the products in this system dont smell very good. I don't think I'll continue using the products because it makes my hair feel uncomfortable all day with the dryness, tangles, stick/sticky feeing.
Not it

I received this item for free from Redken in exchange for my honest opinion. I've tried similar products in the past and didn't get great results…unfortunately I didn't get anything special out of this product, either, other than maybe some extra dirty feeling :(
Best full system
