What the authors write
Biotin is vitamin B7, also called vitamin H, and is found, among other things, in supplements.
Biotin supports processes related to the epidermis and its derivatives, including hair.
Biotin has been identified as an ingredient that benefits the condition of the skin and hair.
Henryk Różański says that biotin may support the reversal of graying, although the hair does not always change color.

A review indicates that biotin may help in cases of deficiency or certain disorders, but there is not enough evidence of benefits for healthy people.
Aim of the study: Biotin has become commercially popular for its claimed benefits for healthy hair and nail growth. Despite its reputation, there is little research supporting the usefulness of biotin in healthy individuals. This study systematically reviews the literature on the effectiveness of biotin for hair and nail growth.
Results: We found 18 reported cases of biotin use for changes in hair and nails. In all cases, patients who received biotin supplements had an underlying condition that impaired hair or nail growth. All cases showed clinical improvement after taking biotin. Although biotin is widely used as a supplement for hair and nail growth, research demonstrating its effectiveness is limited. Biotin supplementation may help in cases of acquired or inherited biotin deficiency and in conditions such as brittle nail syndrome or uncombable hair. However, we believe these cases are uncommon and that there is insufficient evidence to support supplementation in healthy individuals.

In the study, biotin supplements were associated with reduced hair loss and a higher hair growth rate, although the reported results do not establish whether the effect was due to biotin alone.
Aim of the study: Background: Biotin, an essential cofactor for carboxylase enzymes, plays a key role in metabolic processes, while silica is believed to support collagen synthesis, contributing to improved skin and hair health. This study investigates the dermatological benefits of standardized plant-based supplements formulated with biotin derived from Sesbania grandiflora and a biotin-silica blend extracted from Bambusa arundinacea.
Results: Skin elasticity increased to 0.15 ± 0.06 (p < 0.0001) in the biotin group and 0.17 ± 0.12 (p < 0.0001) in the biotin with silica group. No adverse events were reported. Conclusion: Adding Orgen-Bio® and RGen-Si™ to a daily routine may support overall skin, hair, and nail health. The synergistic blend improves elasticity, reduces wrinkles, increases hydration, strengthens hair, and improves nail quality, offering effective, long-term cosmetic and structural benefits.

In a girl with no hair or nail growth, biotin restored their growth.
Aim of the study: Patients with autism spectrum disorder and developmental delay or encephalopathy rarely show no or negligible hair and nail growth, suggesting a biotin-responsive clinical disorder.
Results: Whole-exome sequencing found a de novo pathogenic variant, c.1091 C > T, p.T364M, in the ATP1A2 gene, but no genetic cause was identified in the biotin-responsive metabolic pathways. Treatment with biotin and acetazolamide restored normal mental function and school performance. Poor or absent nail and hair growth in any child presenting with developmental delay and autism spectrum disorder should be considered evidence of a biotin-responsive genetic disorder, even when exome testing is negative.

In an infant suspected of having a biotin metabolism disorder, biotin treatment was associated with rapid clinical and biochemical improvement.
Aim of the study: Multiple carboxylase deficiency (MCD) is a rare, treatable inborn error of biotin metabolism that may cause life-threatening metabolic crises in children during their first year of life. We report the case of a 4-month-old child with persistent seizures, an eczematous rash around the openings of the body, unexplained hair loss with baldness, and severe metabolic acidosis, initially resembling septicemia.
Results: Early recognition and prompt initiation of biotin therapy can lead to rapid clinical recovery. Timely diagnosis is crucial to prevent avoidable illness and long-term neurological complications. This case highlights the importance of considering MCD in children. In the first year of life, timely treatment of unexplained metabolic acidosis can be lifesaving.
