Frizz occurs when the outer layer of your hair (the cuticle) is lifted instead of smoothed down. This lift separates the cuticle and allows moisture to move freely through your hair shaft. As the strands take in moisture, they swell and warp, creating a frizzy look.
Sebum, a natural hair lubricant produced by glands in the scalp, keeps hair moisturized, smooth and shiny. It also provides a barrier against allowing too much moisture in from the environment.
While curly hair isn’t the only culprit for frizz, waves and curls can slow the sebum from traveling down the full length of the hair shaft and block the ends from getting enough of the sebum it needs.
Those with chemically treated hair are also at a high risk for frizzy locks. Chemical treatments strip your hair of oils and peptides, causing split ends and breakage. Broken hair and a lack of moisture are the perfect duo for a frizzy look.

Sulfates, such as sodium lauryl sulfate (SLS), are chemicals used to create strong detergents. Because they are such efficient cleansers and degreasers, sulfates are commonly used in manufacturing and construction industries to clean heavy machinery.
