hair treated with bleaching powder added with the powdered liposome did so only by 4.47%. 3. Hair treated with bleaching powder without liposomes, increased its stretch before reaching the breaking point by 6.6%, while hair treated with bleaching powder added with the powdered liposome did it by 13.0%.


■ Key benefits The powdered liposome ingredient allows for a more secure, efficient and intense bleaching, and is easily incorporated into the bleaching powder during its manufacturing process. It resists a wide range of pHs and the effects of hydrogen peroxide, while being compatible with all types of colouring agents. In addition, it helps to give softness and shine to hair, providing greater strength and elasticity.


Conclusion Decovec is a powdered liposome that is proven to be effective in reducing and preventing damage caused to hair cuticles during the aggressive chemical process of discoloration. This treatment causes hydrolysis of keratin proteins that comprise the cuticle. Hair is shown to have less breakage, is more lubricated, silky and easy to comb. The addition of Decovec to bleaching powders helps reduce the loss resistance of treated hair compared to untreated hair and increases stretch helping to decrease hair loss. Decovec was shown to reduce oxidative damage associated with discoloring powders and prevent the hydrolysis of keratin proteins.
