Effect of A Seboregulating Shampoo on Dogs with Oily Skin: An Open Pet-Owners Evaluation

Abstract

Navarro C., Delaup V., Baise C. and Jahier B.

Keratinisation disorders in dogs lead to excessive skin greasiness, scale formation, and malodour, significantly impacting their quality of life. Traditional treatments using sulfur and salicylic acid have limitations, prompting interest in alternatives. This study evaluates the clinical effectiveness and practical aspects of a new perfume-free seboregulating shampoo, Keratoderm®, containing cider vinegar, lactic acid, and tea tree leaf oil, and enriched with moisturisers and soothing agents. In an open- label evaluation, 20 dogs with oily and scaly skin were washed weekly for 4 weeks with the seboregulating shampoo. Pet owners assessed pruritus (PVAS) and six clinical signs (scaling, skin odour, skin greasiness, haircoat quality, coat shining, coat softness) at days 0, 7, and 28. The keratoseborrhoeic index (KSI) was calculated by adding each individual clinical signs, and product characteristics were rated at the study's end. PVAS significantly decreased from day 0 (7.2±1.8) to day 28 (3.1±2.7). Significant improvements in all individual clinical signs and in KSI were observed by day 7, with further improvement by day 28. Owners reported high satisfaction and no adverse events were reported. The shampoo demonstrated rapid reduction of pruritus and clinical signs, as soon as day 7, in dogs with oily skin, offering a well-tolerated, fragrance-free alternative for managing seborrhoeic conditions. Future controlled studies with larger samples are recommended to confirm these findings and optimise usage protocols.
