REASONS FOR DIFFERENT HAIR TEXTURES.

have you ever wondered why different people have different hair texture? straight hair,curly hair, coarse hair or voluminous hair? or you are just used to seeing different textures of hair and you are like
what ever it is what it is. if you want to know why, read below.

Hair exists in a variety of textures. Three main aspects of hair texture are the curl pattern, volume, and consistency. The derivations of hair texture are not fully understood. All mammalian hair is composed of keratin, so the make-up of hair follicles is not the source of varying hair patterns. There are a range of theories pertaining to the curl patterns of hair. Scientists have come to believe is that the shape of the hair shaft has an effect on the curliness of the individual's hair. A very round shaft allows for less disulfide bonds to be present in the hair strand. This means the bonds present are directly in line with one another, resulting in straight hair. The flatter the hair shaft becomes, the curlier hair gets, because the shape allows more cysteines to become compacted together resulting in a bent shape that, with every additional disulfide bond, becomes curlier in form. As the hair follicle shape determines curl pattern, the hair follicle size determines thickness. While the circumference of the hair follicle expands, so does the thickness of the hair follicle. An individual's hair volume, as a result, can be thin, normal, or thick. The consistency of hair can almost always be grouped into three categories: fine, medium, and coarse. This trait is determined by the hair follicle volume and the condition of the strand. Fine hair has a small circumference in relation to medium and coarse strands; coarse hair having the largest circumference. Coarse hair has a more open cuticle than thin or medium hair causing it to be the most porous.
