I am currently using Moist Diane Moist & Shine Shampoo & Conditioner. The bottles are so big that I am sure they’ll last at least 3-4 months, if not more. Moist & Shine repairs damaged hair from the core with moisture ingredients which leads to smoother, brighter hair.
Not sure if my hair has become brighter or if that is even possible but my hair is smooth and soft. I like both the shampoo and conditioner as they have very pleasant scents and the conditioner is rather concentrated so I just need 2-3 pumps which isn’t a lot.
The products are formulated in Japan and available in Watsons.
