I'm currently growing out my hair, but I struggle with thick, curly hair and a lot of volume. The rainy season is particularly challenging, so every year, as soon as it begins, I get a special treatment at the hair salon. Well, when I arrived at the salon, the hairdresser asked, "Have you ever had a hair quality improvement treatment?" I thought I had tried all sorts of treatments before, so I answered yes, but I had no idea that this hair quality treatment would end up impressing me so much....
