Our keratin hair conditioner contains rosemary extract, panthenol, and maca extract. It can gently nourish hair and deeply moisturize it while removing damaged stratum corneum, enhancing hair elasticity from the roots, making hair softer and more elastic. The usage method is simple: clean the hair and wipe it to 80% dryness, take an appropriate amount of this product on your hand, evenly apply it to the hair, slowly apply from bottom to top, and smooth the hair evenly. It can be used to repair split ends and improve frizz problems, effectively improving hair surface defects, making hair naturally shiny and smooth to the touch.
