Blow dry your hair with a round brush to begin shaping it for this vintage '90s look. Curl it under with a flat iron from your roots to your jaw. Add some beachy waves or loose curls for a more contemporary look. Use a little dab of molding wax to squeeze together small pieces of hair for increased definition. Let it all air-dry. The '90s were all about flaunting your hair style - whether it was classic, modern, or something in between - so if you want to get into character, then give this style a try! Hair tips: If you want to create a fuller look, add an extra roll before drying it completely. This will help it hold its shape better when you release it. Also, use a fine-toothed comb to gently pull out any knots or tangles before washing them away. Your friends and family will definitely notice how well you remember the '90s if you go for this authentic hairstyle!
