Curl Type Guide
Hair Textures
Each individual inherits a unique hair texture at birth, which might undergo transformations throughout life. The degree of curl, wave, or absence thereof, is determined by the quantity of disulfide bonds within the hair proteins located in the hair shaft. More bonds result in curlier hair, while fewer bonds lead to straighter strands.
The Formation of Curls
Hair consists mainly of keratin, a protein that originates from the follicle and is synthesized within the cells of the hair follicle. All proteins become integral components of the hair shaft and include sulfur atoms. When two sulfur atoms unite to form a disulfide bond, the protein bends. If sulfur atoms within the same protein are sufficiently distant and bond to form a disulfide bond, the protein will bend, resulting in the formation of curls.
