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
