This article proposes a universal morphological classification for the human beard, aiding comparative studies and medical communication.Evaluation of hair and beard transplant patients was conducted on 250 males at the Speranzini Clinic over three years. Types of beard presentation were categorized based on morphological features. The classification was progressive from type I to VI. In our sample, the most frequent beard pattern was type V (42.4%, n = 106), with a mean age of 41 (range 21-66 years old).The proposed classification offers a standardized approach for beard evaluation across diverse populations. Further research is warranted to validate the findings in different groups. Despite potential ambiguities, the classification was efficiently applied in the studied population.
