Jon Renau Fiber Love Shampoo review

Fiber Love is the shampoo Jon Renau makes for its own synthetic wigs, and it is the safest default if you wear a synthetic or heat-friendly synthetic style from any of the big brands. Jon Renau describes it as a gentle, paraben and sulfate-free shampoo that restores the salon body and extends the life of synthetic fiber, and the Best Wig Outlet listing adds that it is also free of MIT and sodium chloride. The method is simple: detangle, wet the fiber and base under cool running water, work in a small amount with your palm, and rinse. Jon Renau says not to scrub or soak, which keeps the cap and curl pattern intact. The 2.5 fl oz bottle cost $11.00 at Best Wig Outlet when we checked, and an 8.5 oz size is sold for regular washers. The limits are plain: it is for synthetic fiber only, and Jon Renau's own site is a wholesale catalog, so you buy it through wig retailers.
