Review: 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
Review: So Thankful that this product ACTUALLY WORKS! - I have experienced a noticeable change in hair shedding and loss since purchasing the entire system via desertcart. 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
*by P***A on September 14, 2025*

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.
