FORMULATION AND EVALUATION OF HERBAL HAIR OIL: A REVIEW AND LABORATORY-SCALE 20 mL FORMULATION
Year: 2026
Type: article
Abstract: Herbal hair oils are topical cosmetic preparations containing medicinal plant materials incorporated into suitable vegetable-oil bases. They have traditionally been used for scalp conditioning, hair grooming, maintenance of hair-shaft quality and general hair care. Increasing interest in botanical cosmetics has resulted in the development of polyherbal hair-oil formulations containing plants such as Phyllanthus emblica (Amla), Eclipta prostrata (Bhringraj), Hibiscus rosa-sinensis (Hibiscus), Azadirachta indica (Neem) and Trigonella foenum-graecum (Fenugreek). The present review summarizes the scientific literature concerning herbal hair oils, selected medicinal plants, preparation techniques and quality-evaluation parameters. A proposed 20 mL laboratory-scale polyherbal hair-oil formulation containing Amla, Bhringraj, Hibiscus, Neem and Fenugreek in a coconut-oil base is presented. The preparation involves authentication, cleaning, drying, powdering, controlled oil infusion, filtration and final volume adjustment. Evaluation parameters include organoleptic characteristics, specific gravity, viscosity, refractive index, acid value, saponification value, preliminary phytochemical screening and stability assessment. Experimental literature provides evidence supporting the investigation of coconut oil for hair-shaft protection and of selected botanicals such as Bhringraj and Hibiscus in experimental hair-growth models. Amla has also been investigated in experimental and clinical studies. However, evidence obtained from individual herbs or extracts cannot automatically be extrapolated to the finished polyherbal hair oil. Therefore, authentication, standardization, reproducible formulation procedures and appropriate experimental evaluation are essential for development of a scientifically acceptable herbal hair-oil preparation.
