The Ludwig System is used to determine the type of female hair loss.
Normal hair with no signs of loss
Ludwig I-2 through I-4
The gap in the central part of the hair gets progressively wider, indicating the starting stages of hair loss.
Ludiwg II-1 and Ludwig II-2
The loss associated with Ludwig I-4 expands and becomes more pronounced.
The loss of hair from the part on the top of the scalp out towards the sides of the head is pronounced and extensive, but some hair does remain.
This is a rare condition that has the entire crown of the head bare and hair only remaining in a circular pattern around the scalp.
At the Ludwig Frontal stage, hair is being noticeably lost from the part on the crown and at the front.
