As of 2018, KP is thought to be due to abnormalities in the process of depositing the protein keratin in hair follicles, abnormalities in the hair shaft, or both.[1] KP is usually diagnosed by a medical professional based on the appearance of the skin, but dermoscopy can be used, as well, if the diagnosis is unclear.[1] Variants of the ABCA12 gene have been associated with KP.[5] KP is the most common disorder of the hair follicle in children.[1] How common KP is in adults is unclear, with estimates ranging from 0.75 to 34% of the population.[1] No single approach has been found to completely cure KP, but treatments can improve the cosmetic appearance of the condition. Treatment includes the application of topical preparations of moisturizers and medications such as glycolic acid, lactic acid, salicylic acid, urea, or retinoids to the skin.[1] Fractional carbon dioxide lasers and Nd:YAG laser therapies are also effective.[1]
