SAEDNEWS: Humid air can make hair look frizzy, flat, or less defined because moisture affects the hair fiber and its bonds. Hair texture, porosity, and environmental humidity all influence how strongly these changes appear.
According to SAEDNEWS, hair naturally interacts with moisture in the surrounding air. When humidity is high, water molecules can enter the hair fiber and change the temporary bonds that help maintain its shape. As a result, straight hair may become puffier, while wavy or curly hair can appear more pronounced or lose its usual definition.
Hair porosity also plays an important role. Hair with a more raised or porous outer layer can absorb moisture more easily, causing the strands to swell and become rougher in appearance. Frizz can develop when individual strands absorb moisture unevenly and no longer lie smoothly together.
The effect can vary from person to person because hair thickness, texture, porosity, and existing dryness are different. Keeping hair adequately moisturized, limiting excessive heat, and gently handling the strands can help reduce unwanted changes in humid conditions.
