Walker Just Rite Positioning Spray is applied to the scalp before attaching any hair system, toupee or wig and helps you precisely locate it for the perfect attachment Before it evaporates away it acts as a barrier allowing the wig, toupee or hair system to be slid freely into place. Once Just Rite evaporates away the hold is secure and robust as it would normally be. A great product for perfectionists and beginners alike.
