Mô tả

Olsen's classification system highlights the characteristic triangular or Christmas-tree pattern of frontovertical alopecia seen in female pattern hair loss. The accentuation of thinning at the frontal midline distinguishes this pattern from the more diffuse Ludwig classification.

The Ludwig scale classifies female pattern hair loss into three progressive stages, ranging from minimal thinning at the crown (Grade I) to extensive hair loss across the top of the scalp (Grade III). This grading system remains one of the most widely used clinical tools for assessing FPHL severity.

Sinclair's classification divides midline pattern alopecia into four intensity levels, progressing from a normal-appearing scalp to increasingly visible widening of the central part. The scale, introduced by Sinclair et al. (2005), provides a practical visual reference for clinicians assessing hair loss severity.
