As a beauty professional with two decades of experience, I often discuss the role of internal nutrients like biotin in supporting hair health. However, it's crucial to clarify that Viori is an external haircare brand, and we do not manufacture or sell biotin supplements. Our expertise lies in topical, nutrient-rich hair products.

Understanding Supplement Shelf Life and Potency
That said, I can offer general professional insight on the topic. The shelf life of any supplement, including biotin, is determined by its manufacturer and is typically printed on the bottle as an expiration date. This date indicates the period during which the supplement is guaranteed to contain the full potency of its listed ingredients. After this date, the chemical stability of the vitamin can degrade, meaning its potency may diminish. For hair health specifically, taking a supplement that has lost potency means you may not be receiving the intended level of nutritional support that contributes to the keratin infrastructure of the hair.
The Viori Advantage: Long-Lasting Topical Potency
This principle of potency and stability is one reason why Viori focuses on delivering hair-nourishing ingredients directly to the hair and scalp through our topical formulas. Our shampoo and conditioner bars are designed with a stable, solid format that offers a significant advantage: a long shelf life with maintained potency. When stored in a cool, dry place-such as in one of our bamboo holders away from direct shower spray-our bars can last for 3 years or more without losing their effectiveness.
The key ingredients in our bars, such as our proprietary Longsheng Rice Water™, hydrolyzed rice protein, vitamins B5 and B8 (panthenol and inositol), and nourishing butters, remain active and potent throughout the life of the bar. This ensures that every use delivers the intended benefits:
- Moisturizing
- Strengthening
- Supporting the appearance of healthy, shiny hair
Unlike a supplement that must be processed by the body, the nutrients in our bars work directly on the hair shaft and scalp where they are needed.
