The scientific study of hair, scalp, hair care and associated diseases and disorders is called trichology.

It’s important for every hairstylist to be well versed in trichology because healthy hair is essential for any hairstyle and healthy hair starts with a healthy scalp. Stylists must understand elements of trichology like the life cycle of hair growth and the anatomy of the scalp. What’s more, failure to identify an unhealthy scalp condition could actually help sustain a communicable disease or cause hair loss.

This chapter will cover the specifics of hair growth, scalp disorders and treatments and the best way to perform a shampoo and conditioning service.
