It is well established that Biotin is essential for metabolic processes and hair follicle function, and Systematic reviews and clinical literature consistently report that biotin supplementation benefits only those with underlying biotin deficiency, and there is insufficient evidence that biotin supplementation beyond deficiency improves hair, skin, or nail health in healthy individuals. The popularity of biotin is driven more by anecdotal reports and marketing than by scientific data and clinical research. High-dose biotin (2,500 mcg) lacks strong evidence and carries potential risks if use is prolonged and As of today, there is no robust clinical evidence supporting high-dose biotin for wellness, hair, skin, or nail health in healthy individuals without a deficiency in fact high doses have been associated with rare adverse events and possible teratogenicity in animal studies and The long-term safety profile in healthy populations is not well established.

As a dietician, I think that one should not confuse advertisements with facts. Biotin is a necessary B-vitamin and is important in metabolism, though an actual deficit in healthy individuals is very uncommon. The majority of the population obtains adequate amounts in their normal diet by consuming foodstuffs such as eggs, nuts, and whole grains. It is due to this that studies have not found any regular advantages of a biotin supplement, with regard to hair, skin, or nails, in individuals who are not deficient. It is common in the wellness industry to market high-dose levels of biotin supplements (such as 2500 mcg) as a beauty booster. But these are much higher doses than the recommended amounts to take in daily, and the research has not given much concrete backing to suggest that they enhance cosmetic effects on otherwise healthy people. Indeed, biotin's success in the beauty category appears to be a consumer-driven, marketing-oriented trend rather than a scientific one. That being said, biotin is water-soluble, and any excess of biotin is normally excreted; hence, it is generally safe in most individuals. Nonetheless, I would recommend people to prioritize eating a healthy diet before opting to take supplements. Biotin can be beneficial to those with a deficiency or special medical requirements, but to the average person, it rarely really benefits the beauty beyond what is being stated.
Truth is if someone does not have a biotin deficiency, megadosing is more optics than anything else. It just feels like you are doing something healthy. There is a whole cottage industry predicated on the pursuit of beauty from the inside out. Biotin is sold as if it is some miracle light switch. But in reality, extra biotin is excreted. It is water soluble. Unless you know there is an absorption issue, your body is going to read that label as a side note and flush it. In which case that 2,500 mcg number on the label may sound impressive but it does not equate to stronger hair or improved skin. Kind of like dumping more gas into a full tank so nothing happens. Your body is not going to metabolize the surplus into better nails. At the same time, the wellness industry is good at selling hope in a capsule. And at the same time, to be fair, if someone thinks something helps placebo can take them a long way ... even when the science yawns. If anything, most benefits come from broader support e.g., hydration nutrition circulation, hormone balance. Biotin may get some PR detours but it is not really driving the bus. Honestly, the benefits are far more nuanced than marketing tells people to think.
