A braid-out is a great way to add waves to straight hair or stretch and lengthen curly hair without using a heated styling tool, such as a curling iron or crimper. A braid-out is a healthful style choice for your hair, and it is easy to do. First, wash and condition your hair. Second, part your hair into sections (four sections will usually suffice, but you may want more depending on your preference--the smaller the braid, the tighter the wave pattern will be). Third, gently comb each section and then braid it. If your hair is prone to frizz, you may want to add a small amount of styling gel to each section before braiding. Remember not to braid your hair too tightly--you do not want to have any tension near the scalp. For the safest and healthiest option, let your hair air-dry (time will vary depending on climate and hair texture, but thick hair usually takes at least 12 hours). If you don't have time to let your hair air dry, you can use a blow-dryer with a diffuser or a hood dryer (time will vary depending on texture, but thick hair usually takes at least 60 to 90 minutes). After your hair is completely dry, unbraid each section and let the styling fun begin. Results will vary depending on texture, but you should have some luscious waves to work with--the possibilities are endless.
