Query: Sucks! don't waste your money

This so called serum doesn't do anything for your hair, trust me. I live in a dry area and i apply this serum sparingly, and by mid day I see all dust, basically everything dirty has stuck on my hair! This serum does not hydrate, just makes your hair look oily and dirty! suave keratin infusion is better!
