Cuticle Hair
What
is the hair cuticle?
Human hair has a complex structure that consists
of three layers: the cuticle, the cortex, and the medulla. Cuticle is the
outermost layer of the hair which is made up of tightly packed scales that
overlap each other like roof shingles. It can help to maintain the hair’s
strength and elasticity and prevent damage to the vulnerable inner core.
