What is the Anagen phase?
The process of removing hair from the follicle (root and all), such as waxing or sugaring.

The innermost layer of the hair structure, which estheticians rarely worry about.
What is the Medulla?
When applying soft wax, it is applied in the direction of hair growth, but removed in this direction.
