How to use hair straightener at home. Using a hair straightener at home is a great way to achieve a sleek, straight look for your hair. Here are some steps to follow: 1. Start with clean, dry hair: It’s important to use a hair straightener on dry hair to avoid damage. Wash your hair and let it air dry or use a blow dryer to dry it completely. 2. Apply a heat protectant: Apply a heat protectant spray or serum to your hair to prevent damage from the heat of the straightener. 3. Divide your hair into sections: Divide your hair into small sections using clips or hair ties. This will make it easier to straighten your hair evenly. 4. Adjust the temperature: Most hair straighteners have adjustable temperature settings. Choose a temperature that’s suitable for your hair type. Fine hair requires lower heat, while thick hair can handle higher heat. 5. Start straightening: Take a small section of hair and clamp the straightener at the roots. Slowly glide the straightener down the length of the hair, applying even pressure. Repeat this process on all the sections of your hair. 6. Finish with a serum or oil: Once you have straightened all of your hair, you can apply a serum or oil to add shine and prevent frizz. 7. Clean your straightener: After using your straightener, let it cool down and wipe it with a damp cloth to remove any buildup.
