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...

No unpleasant residue
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. 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 doesn't leave any unpleasant residue on my scalp. 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 didnt give that feeling in 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 my scalp seems happy using this. 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.
Has made my scalp healthy and have new hair growth
Hair Type Straight Hair
[I received this product in exchange for my honest review] I have been using this serum after every wash and wow my scalp feels so healthy. The whole system has greatly helped my scalp and hair, I have thinning hair that was falling a lot due to post partum and medical issues. My scalp prior to using this product was very itchy and I was getting dandruff which I have never had before. Now my scalp is not itchy at all and I have so much new hair growth. This serum does not weight down my hair at all which I was worried about prior to using. It's so easy to use after washing your hair and just style as you normally would.
Immediate results!
My hair has never looked so full and healthy and this is my first time using it! If you have crazy flyaways, you may just meed moisture bc this product sealed/ smoothed my flyaways like I just got a keratin treatment
I would buy this product!

Left my hair limp and greasy
Hair Type Straight Hair
[I received this product in exchange for my honest review] I loved all of the other products in this line, but this one unfortunately left my very fine hair feeling limp and flat. I think it ma be my hair type - it didn't agree with the way my hair absorbs it.
