It locks out frizz successfully. The finish is lovely. My single star deduction is because the bottle arrived with a slight dent, although the product inside was fine. The built-in heat protection is excellent.
This extra strength version is far better than the original for my type 4 hair. The heat-protectant is reassuring. The only drawback is the strong chemical scent during the blow-drying process.
My hair is sleek through 3 washes, which is great. I wish the spray mechanism had a finer mist to ensure more even application. Order arrived on time.
Good for Keratin-treated hair, and the results last. I found the website hard to navigate to find the product description initially, but the checkout was fine. Product performance is strong.
It delivers a beautiful, frizz-free finish. I'd give it 5 stars if it didn't feel so expensive for the amount you get. I appreciate the free sample of another product they included.
