"Herbal blend (proprietary)" is a general term frequently used in supplements marketed for hair health. Such blends typically contain a mix of botanical ingredients, which may include herbs like saw palmetto, horsetail, nettle, rosemary, or ginseng. The use of these herbs for hair health is primarily justified by traditional practices. For centuries, various cultures have used these botanicals in folk remedies to support hair growth, reduce hair loss, or improve scalp condition. For instance, horsetail is valued in European herbalism for its silica content, which is believed to strengthen hair, and saw palmetto is traditionally used in Native American medicine and is now popular in supplements targeting hair loss.

However, scientific validation for the effectiveness of most herbal blends in supporting hair health is limited and inconsistent. While some individual herbs have shown mild effects in small studies (e.g., saw palmetto may have a weak impact on androgenic alopecia), these results are not robust or widely replicated. Overall, most claims about proprietary herbal blends for hair are supported more by traditional use than by high-quality clinical evidence. The proprietary nature of these blends also makes it difficult to evaluate efficacy, as dosages and specific ingredient combinations are often undisclosed.
