Mousse is a versatile foam hair-styling product that can be used on most hair types with great success. When it's first dispensed from its aerosol housing, mousse is a foam that closely resembles delicate whipped cream - but once you put it in your hair, it magically disappears while amping up the volume. Mousse comes in a few varieties, and can be used on curly hair, straight hair and especially on hair in need of a little volume. You can buy inexpensive mousse at essentially any drugstore, or you can select moderately priced mousse at the salon. Apply mousse to wet hair and allow it to air dry, and you'll sport a "wet" look throughout the day. This is a common look with curly hair, and can actually feel crunchy to the touch. For a softer effect, apply mousse to wet hair and then blow dry. This helps give hair a boost in the volume department, and allows you a bit more control over your style. Whether you have curly hair, straight hair or fine hair, there's a mousse out there for you. Hair length also does not matter. One word to the wise: if you have naturally dry hair and you want to try mousse, make sure to get one that does not contain alcohol, but instead, is rich in vitamins and natural conditioners. Mousse for curling hair If you have curly hair, you'll want to look for a mousse product specifically for your hair type. This is because other mousse on the market is made to separate hair and add volume, while curling mousse is formulated specifically for your unique hair texture. Make sure your mousse does not contain alcohol, as mousse for other hair types may. The alcohol can sap natural oils from your hair and dry it out, resulting in a frizzy offense. Look for a mousse with vitamins and conditioners, instead.

Mousse for Volumizing Hair Since oil typically causes hair to lie flat and listless on top of the head, it makes sense that mousse intended to give your locks a little boost would be alcohol laden. This is because the alcohol pulls oils from the hair, which makes each strand lighter. It also coats each strand of hair and then expands. When you coat your whole head in volumizing mousse, this causes all your hair strands to expand and push against one another - hence, volume is formed. Since volumizing mousse contains alcohol, it's so important for girls with dry hair or curls to stay away from this type of mousse. For the rest of you out there, apply to damp hair, then blow dry and style, and you have instant volume!
