Abstract: The hair is a distinguishing feature of animals that has several functions, such as providing warmth, providing protection, facilitating sweating and pheromone evaporation, providing sensory stimulation, and, in certain situations, acting as color-based camouflage. Hair grooming and styling have progressed significantly over the years, and modern hair treatments primarily focus on enhancing hair quality. However, standard active ingredients in formulations display suboptimal performance, and some may present toxicity issues, demanding a stronger formulation design that is appropriate for performance and safety. The need for natural ingredients, such as macromolecules and biomolecules sourced from plants, animals, and marine environments, is increasing among consumers. The favorable benefits induced by including lipid-rich components in Personal Care Products (PCP) formulations are regarded as valuable elements. A lipid-based preparation is specifically employed for innovative medicine-targeted distribution of bioactive substances among all medication administration strategies. The distribution of LBDDS transdermally and topically is exciting since the lipid bilayer might enter the uppermost layer of skin with ease and release medicine in a regulated way. It offers benefits in terms of stability, bioacceptability, and biodegradability, as well as receptor-mediated fast absorption by the particular site. Various lipid-based formulations for hair care therapy have been created, showing some improvement in hair care. This review focuses on several lipid-based formulations for hair care therapy, including their thorough mechanism of action, efficacy on hair care, patents, obstacles, and future prospects, along with the challenges and future prospects in the hair care industry
