- Use a boar bristle brush. Boar bristle helps distribute oil evenly throughout your hair, giving you more shine from root to tip, and causes less breakage than other brush materials.
- Blow-dry by aiming your hairdryer down your hair shaft and away from your head. Doing it this way seals your hair's cuticle, making it smoother and shinier.
- Right before you get out of the shower, do a final rinse with a tablespoon of vinegar mixed into a cup of cold water. The acidity of vinegar restores your hair's Ph balance, and the cold water helps seal your hair's cuticle.
- Put in some hair dye close to your current hair color. A box of temporary color like Clairol Loving Care ($6) helps plump up and smooth the hair shaft, making your hair thicker and shinier. It also washes out after just a few shampoos, so you don't have to worry about it seriously affecting your color. Going darker can also add shine to your hair, but you might want to consult with a stylist on that one.
- Use a glaze. Something like John Frieda Brilliant Brunette color glaze ($10) is a good alternative to heavy shine sprays and creams because you wash it out, so the shimmer you get is weightless.
