Organic henna is a completely natural product that delivers a beautiful, long-lasting color without the use of harmful chemicals. When stored correctly, it generally remains in good condition and retains its quality for 3–4 months. Proper aftercare—such as avoiding water contact, applying a lemon-sugar mixture, and using mustard or coconut oil after some time—helps achieve a deeper, more beautiful stain; the color fully develops after 48 hours, during which time water exposure should be kept to a minimum. For optimal results, expose your hands to clove smoke once the henna has dried; this enhances the depth of the color. Keep it in a deep freezer.
