From genetics, high humidity and heat styling to lack of moisture, stress and over-coloring hair, the causes of frizz are many. Fortunately, many haircare companies have formulated products that help tame unruly and frizzy locks. These products come in various forms, including creams, serums, balms and sprays. While creams work better on hair that needs control and hold, serums provide maximum strength and protection from humidity. Balms, on the other hand, allow hair to be more easily defined and styled without frizz, and sprays help reduce and prevent frizz by coating the cuticles and locking out humidity. Choosing the right frizz-fighting product takes research, as some can be used on wet or dry hair, some are meant to be used before heat styling, and others seal in the style and protect against frizz that might develop throughout the day. Check out what these companies came up with to tame unruly frizz, and to help leave hair looking smooth, sleek and shiny all day. —NICOLE PALMIERI
