What it is
Forget frizz and get straight, manageable hair. This shampoo for fine hair reduces tangles and leaves hair bouncy and moisturized. ★ Dual approach: Ceramides (Ceramide NP, Ceramide NG, Ceramide AP) moisturize hair from both inside and outside the hair, repairing damage intensively. High-molecular-weight keratin (hydroxypropyltrimonium hydrolyzed keratin (wool)) coats the hair surface to maintain moisture and create a moisture barrier. ★ Luxurious silk-based cleansing ingredients (sodium lauroyl hydrolyzed silk) create bouncy, elastic lather. ★ Straightening touch ingredients (hydrolyzed collagen) repair fine hair, adding bounce and body.

It has a nice scent and leaves my skin feeling smooth, but it's not something I absolutely have to use, so I don't think I need to buy the larger size.

I liked the scent, but I didn't feel like it made my hair particularly beautiful, so I won't be buying it again. If anything, it did feel a bit frizzy after using a hair dryer.
I didn't notice it at first, but after using it for a few days, my hair became smooth and silky when I dried it! It stayed smooth the next day too! It has a sweet scent, but the treatment is more subtle and barely lingers the next day. Overall, I prefer the black one.
I love the smell and my hair was smooth even without applying hair milk or oil!
