Make Your Beauty Treatment Last

Prolonging a Haircut

First visit an experienced stylist; a precise cut looks better for longer than one from a novice hand. If you have short hair, which often requires monthly appointments, go with a style that grows out well.

• After a haircut, keep your ends hydrated by using a daily leave-in conditioner. If they look fuzzy some days, work in a dab of shine-enhancing oil to smooth them.
• Five or six weeks after your cut, when split ends start to appear, try an at-home glossing treatment to help seal strands and add shine.
• If you have bangs, trim them. Smooth down dry hair with a comb, then hold your shears so that the tips point up at a slight angle and trim a bit at a time, says Aaron Pursell, a hairstylist at the Bumble and Bumble salon, in New York City. Don't snip horizontally, which can lead to overcutting.
