Hair Reactivity
Meaning ❉ Hair Reactivity is the intrinsic response of hair fibers to environmental stimuli, products, and manipulation, deeply rooted in ancestral care.

Dermal Reactivity
Meaning ❉ Dermal reactivity is the scalp’s physiological response to stimuli, particularly significant for textured hair due to its unique biology and rich cultural heritage.

Sensitization Pathways
Meaning ❉ Sensitization Pathways describe how textured hair and scalp, through biological and historical processes, learn to respond to stimuli.

Skin Reactivity
Meaning ❉ Skin reactivity denotes the scalp's inherent capacity to signal discomfort or imbalance, deeply influenced by textured hair heritage and historical care practices.
