Understanding Hair Structure
Understanding Hair Structure
Hair is a complex structure made up of proteins, primarily keratin, which is also found in nails and skin. The hair shaft consists of three layers: the cuticle, cortex, and medulla. The cuticle is the outermost layer, providing protection and shine. The cortex, which makes up the bulk of the hair, contains melanin that gives hair its color. The medulla is the innermost layer, which may be absent in some hair types.
Importance of Hair Structure
Understanding the structure of hair is crucial for developing effective hair care products. Different hair types require different treatments, and knowing the composition helps in formulating products that cater to specific needs.
