Our black hair essence contains mineral oil and jojoba oil. It can provide sufficient nutrition to the hair, repair damage, and make the hair both black and shiny. The usage method is very simple: gently shake the bottle, take 1 drop of the essence, directly apply it to the roots of gray hair on the scalp, and then apply it to other gray hair areas as needed. Use it with your fingertips for gentle massage in the morning and evening. Consistent use is the key to achieving the best results, and it works best on damp or towel-dried hair. It nourishes the hair follicles, strengthens the hair roots, and turns gray hair into black hair.
