This article came from Paula Begoun. I received it in my email newsletter today.
"Struggling with fine, limp hair isn't easy. It turns out the less you do to fine hair, the better off it is. Anything that contains conditioners or styling agents just adds weight that drags hair down. Consider a shorter cut and then color it. Hair color adds thickness to thin hair because it roughs up the cuticle, which creates artificially induced, but natural-looking, volume. Then all you have to do is use a gentle shampoo, period! The slight stiffness you get from not using a conditioner can also give you all the body you need. Give it a try. If you need to smooth things in place or reduce fly-aways, take an anti-cling sheet from your dryer and rub it over your hair. You can also spray a tiny bit of hair spray on your fingertips and work them through the ends of your hair. This may be just what your hair is looking for."
Hope Paula's words can offer some help. Personally, I think she is great.
