The question "why does it take my hair so long to dry" is a common one, especially for those with thick, curly, or long hair. The answer to this question lies in the structure of hair and the factors that affect its drying time.
Hair is made up of a protein called keratin, which is arranged in a series of overlapping scales. When hair is wet, the water molecules penetrate between these scales, causing the hair to swell and become more pliable. The drying process involves the evaporation of these water molecules, which can take a significant amount of time, especially if the hair is thick, curly, or long.
