Simply speaking, a hair volumizer is a serum or lotion that gives great body and thickness to hair. It plumps up each hair strand. A volumizer is usually applied to damp hair that has been shampooed. Massage in, and then blow-dry for amazing big hair.
Volumizers are wonderful for fine, limp locks, or even for those of you who have lots of hair, but hair that isn't thick. Volumizers get rid of fly-away strands and also lend you a bit more control over your crowning glory.
Here are some tried and true hair volumizers:
Frederic Fekkai All Day Hair Plump ($95.00, 3.5 fl. oz.)
KMS AMP Volume Reconstructor ($15.95, 25.4 fl. oz.)
There are many, many hair volumizers out there, and all with unique body-building properties. From sunflower seeds to soy beans to peptides of sorts, all designed to pump or plump up the volume. Some work better than others. Try a few. And watch your hair get bigger and bigger!
