What can I do to make my hair look shinier?
That depends on your hair type. If your hair's curly, chances are it's dull because of dryness. Switch to a moisturizing shampoo and conditioner and apply four to six drops of a silicone-based shine serum to your wet tresses.
If it's wavy, lather up with a shine-enhancing shampoo and conditioner. Rinse well, then spritz a silicone-based shine-enhancing spray from ends to roots. Dry hair using a blow dryer with a tapered nozzle to direct air down the hair shaft and seal the cuticle.
If your hair's straight, it could be accumulating shine-dulling grease, since straight hair hangs flat against the scalp, where oil is produced. Be sure to use a deep-cleaning shampoo daily and a clarifying gel treatment, like J.F. Lazartigue's Propolis Jelly Scalp Treatment, weekly.
