A process for treating balding spots and a composition which when applied to areas of thinning or balding hair increases the width and visibility of the hairs within the thinning or balding area and thus obscures visibility of the scalp or skin underlying the hairs. A bonding agent helps make the spray more efficient in application, decreases undesirable overspray, and increases formula adherence to hair shafts.
