Best shampoo for thin/
I have very thin and fine hair. My hair can barley go a day after a wash without getting greasy. This shampoo and conditioner literally saved my hair. Definitely the best smelling one redken has. My hair feels great, healthy, and full. Also it’s the longest lasting shampoo and conditioner I have that I can go without washing it! So buyyy

So Thankful that this product ACTUALLY WORKS!
I have experienced a noticeable change in hair shedding and loss since purchasing the entire system via Amazon. My hair used to cover my shower and clog the drain AND still comb out a clumps with little breakages and shedding every time I styled. I am used to having thick hair and so this was the norm for me - about 1 1/2 cups worth hair loss at hair wash time. Since using Redken hair system, barely 1/4 cups worth or tablespoon worth of hair loss even when combing my hair post shower. I am a new regular consumer of this hair system. I am so thankful for this product. I am actually outgrowing my hair extensions lol and I want LONGER ones, now that my hair is actually growing past my shoulders - when from two pack of hair extensions to 1pack just to supplement my unevenness from when my ponytail was breaking my hair in a specific area. That area has grown about 4 inches but hasn’t caught up to the rest of my head yet. 🙌🏽✨🥰 Also, my previous shampoo and conditioners are Paul Mitchell - Awapuhi. So it’s not the price that matters, it’s what is IN this hair care system. I was hesitant because of the price and the amount of product. I wash my hair about once per week. Hair has grown approximately 2-4 inches and noticeable in a month the difference. I hope this review helps and makes sense - I rarely leave reviews, but I am so happy with this product, that I made the time! Picture is for reference of the smaller amount of hair loss.

Strengthens and leaves hair soft
I loved this conditioner. It leaves the hair soft, easy to detangle, and with less breakage when combing. The scent is light and pleasant. It is a bit pricey for the size, but it’s worth it for the results.

Buy it! You need this set!
Coming here to say- BUY IT! I originally purchased this set for the growth factor. But If you are looking to TRULY get rid of the Frizz- this shampoo & conditioner will do it. I noticed a difference after the first wash!! While in the shower. Before I dried my hair I forgot to put heat protectant on it and my hair still was not frizzy after blow drying!!!! My hair feels amazing. Soft- yet luscious. The areas were breakage would stick out and not lay flat, now sits softly flowing with the rest of my hair- instead of frizzing and sticking out. I’m shocked how my hair looks and feels after the first wash and condition. I will never use another shampoo and conditioner again. Worth the price tag 1000% Will update on growth in a few months.

Great scent, stiff outcome
I didn't find this conditioner to be a win for my knee length hair. I was hoping it would soften my hair but it made it stiff like my hair feels when I use a keratin product for too long. It does, however smell really nice! I tried this one & the gold bottle made for softening & for me, that product works so much better, but I do prefer the scent of this one. I think it smells sort of fruity, sort of sweet like cotton candy. It's really nice but once rinsed, not overwhelming.

this product will make a difference in your hair!
I love these product! The conditioner is a must-have for anyone dealing with damaged, weak, or over-processed hair. The formula of this conditioner helps strengthen the hair. After about 2 weeks of using it you can see the difference, I started to see less hair in the shower, and the split ends better. Now my hair looks healthier, and is easier to manage.

Great for long hair
Great for long hair, makes it soft and silky. I have to wash my hair more often though because it gets oily faster.
