The oft discussed and fretted over environmental influences on hair have led to a popular consensus which suggests that elevated temperature and humidity lead to frizzier, wilder hair. However, few attempts at actually quantifying these effects have been made. Although frizziness is usually perceived visually, here the influence of variations in temperature and humidity on the tactile perception and friction of curly and straight hair were investigated. It is shown that changes in humidity may disproportionately affect perceived frizziness of curly hair by touch due to concurrent changes in the tactile friction.
人们经常讨论和担心环境对头发的影响，这导致了一种普遍的共识，即高温和高湿度会导致头发更加卷曲、毛糙。然而，实际上很少有人试图量化这些影响。虽然卷曲度通常是通过视觉来感知的，但在这里，我们研究了温度和湿度的变化对卷发和直发的触感和摩擦的影响。结果表明，由于触觉摩擦的同时变化，湿度的变化可能会不成比例地影响人们通过触摸感知卷发的卷曲度。
