Hibiscus (Hibiscus rosa-sinensis)

An emollient (meaning it helps the cuticle of the hair lay down) and a demulcent (meaning it leaves a light soothing film behind) this herb has a cooling effect. It stimulates hair growth, increases hair thickness, reduces and prevents graying, balding, hair-loss, dandruff, split-ends, and many other hair conditions and many scalp disorders. It is also an excellent natural conditioner that may impart a warm reddish color to hair.
