Before I get into the product itself, let me give you a little background on my hair! About two years ago, I was fully platinum blonde, and my hair was absolutely fried, extremely damaged, and super short. Fast forward to today, and my hair is back to its natural color, healthier than ever, and has grown so much! I genuinely attribute a lot of that transformation to this product. For reference, I have very thick, 2A/2B wavy hair that leans more toward the high-porosity side. The shampoo does an amazing job of cleansing my scalp while still keeping my roots hydrated. My hair always feels incredibly fresh and clean without feeling stripped. As for the conditioner, don’t let the thinner consistency fool you! Once I apply it and let it sit, it leaves my hair feeling so soft, hydrated, and manageable. It also does an incredible job of detangling, which is a huge plus when you have thick hair like mine. What I love most is how well this duo helps me maintain healthy hair, especially since I frequently use heat styling tools. After everything my hair has been through, this product has truly become a staple in my routine. Overall, I absolutely recommend it, especially if you have thick, wavy, or high-porosity hair! It’s been a game changer for me!
