SALT score is a quantitative assessment scale for the evaluation of percentage of scalp hair loss.

The percent surface area of each of the 4 scalp is determined: Vertex (top): 40% (0.4) of scalp surface area; each side of scalp (right and left profile): each 18% (0.18) of scalp surface area; posterior aspect (back) of scalp: 24% (0.24) of scalp surface area. The percentage of hair loss in any of these 4 aspects is calculated as the percentage of hair loss multiplied by percent surface area of the scalp in that area. SALT score is the sum of product of each section in the above mentioned areas. SALT score is calculated before and after therapy.

Lowest value: 0%: indicates abscence of clinical disease, Highest value: 100%: indicate 100% affection of the scalp
