SALT Score Diagram

Clinical Notes:

  • The SALT score assesses the severity of alopecia areata by measuring scalp hair loss
  • Total score ranges from 0 to 100, with higher scores indicating more severe hair loss
  • The scalp is divided into four regions: Left (18%), Right (18%), Top (40%), Back (24%)
  • Each region's contribution to the total score is calculated as (hair loss % in region) × (region weight % / 100)
  • The total SALT score is the sum of the contributions from all four regions
