Fundamentals of Hair Science

Course Overview


This course offers a broad overview of current hair science and hair care technology as it relates to the cosmetics and personal care industry. The fundamentals of hair biology and structure will be reviewed, along with the optical properties of hair and hair volume. In addition, effective hair measurement technologies will be discussed, as well as formulation strategies and challenges related to the development of effective hair care products.

The course is ideal for anyone interested in learning more about hair science and hair care technology used to develop quality products in the cosmetics and personal care industry.
