TLDR Healthy hair and scalp depend on overall body health.
Trichology, the study of hair and scalp health, emphasized that hair conditions such as Telogen Effluvium, Alopecia Areata, Androgenetic Hair Loss, Traction Alopecia, Psoriasis, Seborrheic Dermatitis, and Pityriasis (dandruff) reflected the overall health of the body. Trichologists examined body systems, nutrition, hair chemistry, and the physiology of hair and skin to treat these conditions, advocating for an inside-out approach to achieve a healthy scalp through a healthy body.
