 WHEN SHOULD 1 USE A DEEP-CLEANSING SHAMPOO
 WHEN SHOULD 1 USE A DEEP-CLEANSING SHAMPOO?Â
 Use lots of styling products, live in a hard water zone or swim a lot? Use twice a month. Oily hair? Use daily. For the rest, use a clarifying, purifying or chelating formula only when hair seems dull or resistant to regular products. Coloured hair, try a vinegar rinse: % cup white vinegar in 1 cup water, left in for 1-2 minutes after shampooing and conditioning, then rinsed out.
I NEED TO USE A DANDRUFF SHAMPOO. BUT CAN I GET SHINE AND VOLUME TOO?Â
 Many dandruff products now offer volume and shine (try Head & Shoulders) too. Or use other shampoos for shine/volume on alternate days.Â
