As noted, although depilatory hair removal has stayed relatively consistent, the current trends are to develop more naturally based depilatories or those that remove hair as well as affect the hair growth cycle. The challenge of developing natural depilatories is that hair removal by chemical action requires high-pH ingredients and these are not easily found in nature, or they often do not have comprehensive safety substantiation. For the most part, natural claims are associated with the use of botanical ingredients or those not directly associated with depilation action. A good example is Zingiber officinale (ginger) root extract, which can minimize hair growth and thus reduce the frequency of shaving required.
