[I received this product in exchange for my honest review] I have used Redken products in the past and had a favorable experience, so I was very excited to try this.

Great!
Hair Type Straight Hair
[I received this product in exchange for my honest review] I'm a big fan of this product! The packaging feels high quality. There's a button to lock the spray, which i haven't seen before. Makes it really easy to travel with! The nozzle is a very nice fine mist. You do have to wipe it after you use it or else it gets clogged
Hair looked fuller after first use
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I've been using the full system for a little over 6 weeks now. Im currently 9 months post partum with my 3rd (you can see the baby hairs in some photos) so thinning has been a major concern for me.t the whole line/system has a very pleasant fragrance that I also feel is gender neutral. Its not over powering but I can still smell it days later. Overall I dont know if I've seen a huge difference yet but my hair has felt a little fuller, enough so its given me a little more confidence again. I do wash my hair about 1-2x a week so I have only been applying this after washing. I was pleasantly suprised to find this is easy to apply and only leaves a mild crunch feeling after drying (like when you use a lot of mousse and need to scrunch it out to get it softer again) I dont use a lot of styling products (mouse, hair spray, dry shampoo, etc) because I hate the feeling of product in my hair but this wasn't too bad, improved with brushing and my hair still felt clean after using. It doesn't make the hair look greasy either which is another concern I had. I didn't have to increase the frequency of washes either (it didnt make it get greasy faster or anything). My hair looks shiny and healthy without feeling weighed down and this wasnt irritating on my scalp at all. I felt like my hair did look fuller/plumper after using (even with the first use). I'm curious to see if I notice any more significant change after using longer. Overall I think this has helped some and I would recommend to anyone with concerns of thinning.
Good With Work
Hair Type Straight Hair
[I received this product in exchange for my honest review] Same super fresh, almost masculine scent as the shampoo. The spray is closer to a stream, maybe to keep it at the root. Helps to add lift and fullness, but you really have to work it in so it's not crunchy. Looked great after I was done, drying my hair and working it in though.I received this an exchange for my honest review.
Meh
This product is nothing special. It goes on crunchy - you've got to really comb it through - and takes forever to dry. I cannot say it adds anything to volume that any other product would add. I can say that if you like being driven absolutely crazy by a dispensing cap that will break easily, then this product is the one for you!
Adds fullness to hair
Hair Type Straight Hair
[I received this product in exchange for my honest review] I personally didn't like using this product as it would weight down my hair too much if I used it after using the scalp serum. It would make my hair stiff that I could not really run my fingers through my hair. However it did make my hair seem fuller.
