You Wanted to Know About Hair Extension

Weave (or Sew-in) Hair Extensions. Your natural hair is braided in rows from ear to ear and wefts of hair are woven (with thread) onto the braids.
The Rundown

Finding the right extension method will depend on budget, preference, and hair type. While fusion and tape-in extensions can be used on just about any hair texture, weaves are best suited for curly, kinky hair. “Weaving extensions are best for African-American hair, which has enough strength and texture to hold the cornrow braid,” says Chabbi. Fusion extensions tend to be the most expensive ($500 to $4,000) and have the most time-consuming application process (up to three hours); they also last the longest (three to four months). The tape-in application process is much faster (about an hour) and more affordable ($300 to $2,000), but requires more frequent maintenance (every six to eight weeks). “The same tape-in extensions can be removed and reapplied, though,” says Conner. “You don’t have to purchase new hair each time.” The same goes for weave-in extensions, which last about three months, can be applied in an hour or two, and are the most affordable option of the bunch ($100 to $1,000). (Fusion extensions are a one-shot deal; once removed, you can’t use them again.)
Human Versus Synthetic Hair

When it comes to purchasing hair, you get what you pay for. Price will vary greatly based on quality of the hair, as well as the desired quantity (for thickness) and length. Virgin (never-before-processed) Remy human hair is the highest quality and runs upwards of several hundred dollars per bunch (and some heads may require more than one). “The hair cuticle is preserved, instead of stripped, and all the hairs run in the same direction, maintaining that natural soft, silky texture,” says Conner. Synthetic hair is much cheaper ($50 to $100) but won’t blend or style the way human hair does. “It can’t always withstand heat styling and tangles easily,” says Chabbi. It can be a great way to try out extra length or bangs without a big commitment, though.
What to Look For

“It’s important to match the color and texture of the hair extensions with that of your natural hair,” says Conner. Touch the hair first. “If it feels dry, it’s going to tangle more easily,” advises Chabbi. And avoid hair with excessive shine: Shiny hair is coated with silicone, which will wear off quickly and lead to tangles and dulling. As for your stylist, experience is a must. “Improper application or removal is when damage can occur,” says Chabbi. And Conner recommends looking for someone with a colorist background: “If the color match is off, your extensions will be very obvious,” she says.
How to Cut and Style

Good extensions should be entirely undetectable—blending your natural hair with the extension is critical. The best way to do this? A great cut. “After the extensions are in, your hair should be cut dry, with layers that blend the two hair types,” says Chabbi. You can color extensions darker (no bleaching!), but it’s best to choose a shade close to your natural color to avoid overprocessing. Or you can mix and match various shades for a more natural-looking blend. As for at-home styling, extensions should allow you to wash and wear.
TLC

Extension hair should be cared for just like your natural hair: gently. “Be extra careful with wet hair,” says Chabbi, who advises drying hair completely with your fingers before using a brush to style. Avoid tugging or yanking at the extensions while brushing. Instead, hold hair at the root, and begin detangling starting at the ends. You can use all of your favorite hair products, but keep oils away from the roots in order to prevent the bond, tape, or weave from slipping. “At bedtime, put your hair in a loose braid so it doesn’t get matted or tangled while you sleep,” recommends Conner.
The Damage

“The weight of extensions can put additional stress on the roots, so it’s important to match hair density to avoid unnecessary tension on natural hair,” says Conner. In other words, if you have fine hair, your extensions should be a lighter density; those who have thicker, more coarse strands should look for hair with medium density. Placement is also essential. “Extensions should be placed where hair is strongest,” says Chabbi. “Avoid areas along the hairline or the back of the neck, where hair is the most fragile.”
