The plant ethosome hair loss preventing pilatory stays on scalp for a long time, and the effective components can fully play a role by using a far infrared heater.
The plant Ethosomes (Ethosomes) in the invention are novel flexible liposomes which are most concerned in the fields of medicine, pharmacy and cosmetology in recent years and are composed of low molecular weight alcohols (ethanol, propylene glycol, isopropanol), phospholipids, cholesterol and water; the ethosome is used as a carrier of a novel transdermal drug delivery system, and has the remarkable advantages of high encapsulation efficiency, large drug-loading rate, small particle size, good transdermal efficiency, large skin retention and capability of transferring intracellular drugs; there are two main mechanisms for promoting transdermal absorption, one is a penetration mechanism: the vesicle structure formed by the ethosomes carries effective components to directly penetrate through the stratum corneum, and due to the existence of alcohol in the phospholipid layer, the liposome has better flexibility and membrane fluidity, so that the penetration depth is high, and the transdermal efficiency is obviously improved; secondly, a fusion mechanism: the phospholipid of ethosome fuses with stratum corneum lipid, the compact and ordered structure of stratum corneum is disturbed, and simultaneously the effective components are released from the vesicle and independently permeate into the skin.
According to the invention, under the condition of adding the plant ethosome, the plant penetration enhancer is added at the same time, so that the incompletely encapsulated plant molecules are helped to penetrate into hair follicles to play a role of promoting the growth of the hair by the plant molecules.
Advantageous effects
The invention provides a plant ethosome anti-hair loss pilatory and a preparation method and a using method thereof. The invention takes the plant which promotes the hair growth and the blood circulation as the raw material to prepare the plant ethosome, the plant penetrating agent is added to further promote each effective component to enter the hair follicle, the plant ethosome is prepared into liquid, emulsion, gel and paste, the special using method is adopted to lead the effective component to stay on the scalp for a long time, and the penetration and the action of the effective molecules are further promoted by the heating of far infrared rays. The plant extract effective for growth of the hair is prepared into the ethosome, and the vesicle structure formed by the ethosome has better flexibility and membrane fluidity, can carry effective components to directly penetrate through the cuticle, obviously improves the transdermal efficiency, and is added with the plant penetrant to help the incompletely encapsulated plant molecules to permeate into hair follicle cells to play the role of promoting the hair growth of the plant molecules. When the plant ethosome anti-hair loss pilatory is used, the plant ethosome anti-hair loss pilatory can be kept on the scalp for a long time, and the far infrared heater is used for heating to promote the blood circulation of hair and the penetration of effective components, so that the aims of preventing hair loss and promoting hair growth are fulfilled.
