Modified Basic And Specific (BASP) Classification For Pattern Hair Loss

In 2019, a study involving 138 patients (82 males and 56 females) with pattern hair loss introduced a modified Basic and Specific (BASP) classification system to better classify frontal hair loss and include temporal (T) and occipital (O) involvement. The modified classification showed an accuracy of 71.4% for the final type and 96% for T/O type, compared to the existing BASP classification's 82.5% for the final type. However, the modified system was found to be less user-friendly, with ease of use rated lower by practitioners. Despite this, the modified classification was deemed valuable for its ability to classify previously unclassified types of pattern hair loss, with the expectation that accuracy and ease of use would improve with practitioner experience and real scalp examination.
