Using After Midnight hair dye is easy. First, make sure to do a patch test on a small area of your skin. Wait 24 - 48 hours to check for any allergic reactions. If all is well, you're good to go. For best results, lighten your hair to a very light level 9 blonde or lighter and tone it if it has yellow tones. Then, apply the cream - formula dye evenly to your hair. Leave it on for the recommended time, usually around 20 - 30 minutes, and then rinse it out. Since it's a semi - permanent colour, it'll gradually fade with washes. To maintain the colour, use a colour - safe shampoo and conditioner. Avoid excessive heat styling as it can cause the colour to fade faster. And always keep in mind, if you feel any redness or itching during or after use, stop using the product immediately.
