Open the CIPO recordAbstract From the Canadian patent
Long term removal of hair is achieved by delivering a collagen cleaving agent intradermally or subdermally. This is thought to disrupt the fine collagen network anchoring the hair follicles within the dermis and additionally by altering the normal functioning of the dermal papilla cells located in the base of the hair follicle. The method of removal is applicable to animal husbandry methods such as maintaining the breech of sheep hairless and thus has application as a substitute to mulesing. The method is also applicable for cosmetic hair removal.
