What is Kelp Extract?
Kelp extract is derived from brown seaweeds, particularly those from the genus Laminaria, through a process that typically involves drying, milling, and water extraction. It is commonly used in various applications, including supplements and personal care products.
In hair care products, kelp extract is prized for its potential to nourish the scalp and hair due to its rich mineral content, including iodine, which may promote hair health. While some suggest it offers benefits for hair strength and growth, scientific evidence on its efficacy remains limited.
When you see kelp extract on a label, it's often included for its potential to enhance the product with natural minerals and compounds that might have health-promoting properties, though more research is needed to solidify these claims.
