Chemical hair straightening changes hair proteins and mostly fixes broken bonds.
research Wetting behavior of human hair fibers
Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
research The shampoo pH can affect the hair: Myth or Reality?
Shampoo pH can affect hair health, with alkaline shampoos potentially causing damage and acidic shampoos reducing frizz.
