research Genome-Wide Association Meta-Analysis of Individuals of European Ancestry Identifies New Loci Explaining a Substantial Fraction of Hair Color Variation and Heritability

94 citations , April 2018 in “Nature Genetics”

This study identified more than 100 genetic loci associated with hair color variation in Europeans, explaining a significant portion of the trait's heritability and advancing understanding of hair pigmentation.

research Genetic Prediction of Male Pattern Baldness

133 citations , February 2017 in “PLoS Genetics”

In this study, researchers used genetic data from over 52,000 men to identify over 250 genetic loci associated with severe hair loss and developed a predictive algorithm for determining hair loss risk.

research Prediction of Male-Pattern Baldness from Genotypes

37 citations , October 2015 in “European Journal of Human Genetics”

This study found that a genetic model using SNPs can predict early-onset male-pattern baldness with moderate accuracy, which may assist in decisions about interventions.

research Evaluation of DNA Variants Associated with Androgenetic Alopecia and Their Potential to Predict Male Pattern Baldness

48 citations , May 2015 in “PLOS ONE”

This study found that a genetic test using 5 to 20 SNPs can predict male pattern baldness with variable accuracy in European men, especially those aged 50 and older.

research Improving Human Forensics Through Advances in Genetics, Genomics, and Molecular Biology

383 citations , February 2011 in “Nature Reviews Genetics”
