Many products on the market will offer your hair the little boost it needs to look full and healthy. Voluminizing shampoos, conditioners and thickening serums temporarily plump up the hair shaft, creating a fuller head of hair. But if you have fine hair, you know these products are rarely effective all by themselves. I find I get more results combining them with a good blow out to get everything in place. Get yourself a large round brush and blow dry sections of your hair around the brush for a great, full look. If you don't have the time (or patience) to stand there and do your whole head, you can also use rollers with your blow dryer and just leave them in a little longer.
