Silk bases offer you a lightweight, but very realistic looking scalp for your custom unit. Undetectable, soft and breathable. Primarily used for freestyle or permanent parts. We offer a choice of 4 colors (transparent, light brown, medium brown, dark brown) for use in Custom Wigs, Jewish Wigs, Closures and Frontals. Choose the color closest to that of your scalp. When purchasing your Custom Made to Order Product, you may select the Silk base option and then select your color preference.
