Model's know that shiny and luxuriously looking hair is where it's at!
Moisturizing shampoos and conditioners often leave a residue on the hair shaft that inhibit the strand from reflecting light. To make your hair vibrant, by helping the hair cuticle bounce off light again, try using some of the new products that are available ... similar to putting a clear top coat on your nails after painting them for added protection and shine.
A professional salon often offers these gloss or glaze services that will last 2-4 weeks, but to do it at home I recommend using one of these 2 products once a week in the shower; they won't leave your hair greasy and really boost the shine ~ John Freida's Color Glaze Clear and Alterna Cavaiar Shine Boost, $25 at Sephora, but a bargain for $15 on Amazon. To use them, just shampoo and condition as usual, squeeze out the excess water and apply the gloss waiting 3 minutes to rinse with cool water. Or go green and use a bottle of beer or the juice of a fresh lemon squeezed into about a cup of water, but you'll need to leave these on a bit longer to see results, 15 to 20 minutes before rinsing.
Go ahead get your SHINE on!
