where:
• Hair density can be estimated or based on counting hairs using the Harvard rating scale: 1 - 10 hairs per square cm; 11 - 100 hairs per square cm; 101 - 200 hairs per square cm; > 200 hairs per square cm.
regional hair score =
= (quality) * (density) * (percentage)
Interpretation:
• minimum regional score: 0
• maximum regional score: 12
percent of maximal regional hair score =
= (regional score) / 12 * 100%
