Vigorol Liquid Hair Straightener is a lye-free hair-straightening product. The active ingredients include water, ammonium lauryl sulphate, ammonium thioglycolate and ammonium hydroxide. Perfumes and dyes make up the rest of the ingredients. The product is designed to be applied to hair, left on for a short amount of time, and then combed out. It is not recommended for use on damaged, bleached or color-treated hair.
Things You'll Need
Shampoo hair, if necessary, before applying the straightening liquid. If you prefer you may simply wet your hair under running water before applying Vigorol Liquid Straightener.
Pour 2 oz. of the product into the palm of your hand. It is important that you use enough of the product to cover your hair from scalp to ends. You may adjust the amount for very long hair, or very short hair. Make sure to use enough of the product to provide complete hair coverage.
Work Vigorol Liquid Hair Straightener into your hair, as if your were shampooing it.
Leave the product on your hair for at least 10 minutes. If you have fine hair or hair that straightens easily, the maximum time you should leave the product on is 15 minutes. If your hair is medium to thick textured, or if you have had difficulty straightening in the past, leave the product on for 20 to 30 minutes. Do not leave Vigorol Liquid Hair Straightener on your hair for longer than 30 minutes.
Comb the product out. Use a fine-toothed comb to remove the product from your hair. Do not rinse, as this may counteract the desired effect of the product.
