Make your blowout last up to three days with a few simple precautions and tricks.

Instructions

• Step 1: Pull your hair back with an elastic hair band before washing your face or applying face cream, which can bleed into the hairline.
• Step 2: Mist your hair with water, and blow-dry it on the morning of the third day. Follow up with dry shampoo sprayed into the roots and brushed through thoroughly.
• FACT: The first electric hair dryer was invented in France in the 1890s, but it didn't catch on until the 1920s, when the size got smaller.
• TIP: Don't use a flat iron, which will make your hair limp after the first day.
• Step 3: Fluff limp strands the next day by lightly misting the front and top sections. Then blow dry again with round brush.
• TIP: Mousse and volumizing spray contain alcohol, which can help absorb excess oil. Use half your normal amount.
• Step 4: Sleep on a satin pillowcase to prevent tangles. If you must tie your hair back, tie it loosely to avoid creases.
• Step 5: Wear a shower cap to bed to protect your hair from getting mussed, and always wear one in the shower.
• Step 6: Blow-dry your hair while using the round boar-bristle brush and an ionic hair dryer until your hair is completely dry. Don't use pomades or shine serums, which will trap dirt and oil.
