The Rene of Paris Light Conditioner is a gently scented conditioner that is perfect for synthetic wigs and revitalizes dull hair leaving it soft & shiny all day long. How do I use it? While holding the wig at the base, apply light conditioner to the wig at the base and apply the light conditioner to the wig working through the hair in a downward montion. Rinse thoroughly with lukewarm water.
