BACKGROUND: Diffuse hair loss and shedding is often managed with food supplements, yet evidence for ingredient combinations is limited. Our exploratory study evaluated a nutritional supplement (Priorin capsules, Bayer) containing millet extract, pantothenic acid (vitamin B5), L-cystine, and biotin (vitamin B7) in healthy subjects with light diffuse hair loss.
METHODS: In this open-label, intra-individual, multicenter study, subjects with non-illness-related, light diffuse hair loss used the product (two capsules/day) for 12 weeks. Endpoints included objective measurements of hair density, hair growth coefficient, and hair loss (phototrichogram), subjective evaluations of hair appearance, beauty and volume (hairdresser-rated), consumer perception and acceptance, and tolerability.
RESULTS: In 112 subjects (mean age 32 ± 1 years; 93.8% female), hair density (n = 109) and the proportion of hairs in the anagen phase increased significantly, while the telogen proportion decreased (p < 0.001, week 12 vs. baseline). Hair loss had declined by 59% at week 12 (p < 0.001). Significant improvements in the hairdresser-rated hair quality and appearance parameters (shine, softness/elasticity, strength, smoothness, dryness, vitality, volume) were observed (p < 0.001). From week 2, subjects reported progressive improvement in appearance, growth, and slowing of hair loss. At week 12, 90% of subjects perceived improved hair appearance and growth, 85% reported slowing down of hair loss, and 82% were satisfied with the overall hair improvements with treatment. The supplement was generally well tolerated.
CONCLUSIONS: The combination of millet extract, pantothenic acid, L-cystine, and biotin was associated with reduced hair loss, improvements in hair growth and appearance, and high subject satisfaction, and was well tolerated over 12 weeks.
