### ⭐⭐⭐⭐⭐ So Thankful that this product ACTUALLY WORKS!
*by M***1 on December 20, 2025*

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.
