What woman doesn't want skin that glows or hair that shines? Exactly. The geniuses in cosmetic science are constantly working to provide products that give your face that dewy, youthful glow or "hair so healthy, it shines". Fortunately, cosmetic scientists are highly educated in the fields of chemistry, biology and physics. We know what your skin and hair needs, the particulars about how light is reflected and exactly what ingredients will produce the end effect. Here's the science in a nutshell...
In order to create shine, the surface in question must be great at reflecting light. So in the lab, cosmetics are made with ingredients that have a large flat surface area (for optimal light reflection) that will rest on the skin or coat the cuticle layer of the hair. There are some simple things you can do at home to help out. Product build up, dirty skin and clogged pores cause scatter--- light bouncing off a surface all willy nilly--- which results in the appearance of dull skin and hair.
To improve the appearance of your skin, exfoliate once a week. Include it in your Sunday ritual so that you start the week looking gorgeous darling!!!! For your face, follow up with a toner and moisturizer suitable for your skin type. For your body, use your usual lotion, cream, or body butter.... in the winter months you may want to mix in a little light oil.
Now for the hair... shampoo and deep condition your hair once a week. This is imperative for healthy hair. Dirty hair and scraggly ends are sure to cause scatter. Use cool water for your final rinse. This will help smooth the cuticle layer and encourage natural oil production from the scalp. Use a blow dryer or a flat iron as a final step to smoothing the cuticle layer. You may or may not see instant results, but over time your hair will be light, fluffy and shiny.
Here's to the glam life!
