We do not recommend the colouring of Showpony Hair Extensions, or the use of toning shampoo and or conditioners. If you choose to do so we recommend this only be performed by an approved Showpony Hair Extension Stockist. For a list of Showpony Approved Salons, please visit our salon finder. Colouring the Extensions may also void the warranty. Please refer to https://www.showponyaus.com.au/pages/returns-exchange for returns policy.
