The community rejects the common misconception that wetting hair daily is inherently damaging, characterizing the concept of "hygral fatigue" as a myth lacking solid evidence.

The concept of hygral fatigue is based on the idea that repeated water absorption causes the hair fiber to swell and weaken. However, as chemist Michelle Wong (Lab Muffin) explains, robust scientific studies supporting significant structural damage from water alone are virtually nonexistent. While hair is indeed more vulnerable when saturated with water, simple exposure without excessive mechanical manipulation does not cause proven breakage. Research indicates that hair damage stems more from dry brushing, heat, or chemical treatments than from natural hydration. It is important to distinguish between wetting hair and the excessive use of harsh shampoos, which can alter the natural protective film. The community shows a clear and unified consensus in favor of this nuanced view, rejecting unfounded fears regarding the daily use of water.
