Hair extensions done in a salon can take six to eight hours to install and can cost upwards of £1,950, according to an interview with Barbara Lhotan on If you've always wanted long, luscious hair but don't have the time or cash to spend on a professional installation, bonded hair extensions may be perfect for you. When applied carefully at home, bonded extensions can last up to three weeks, require minimal maintenance and look as natural and beautiful as the "real thing."

Skill level:

Things you need

  • 2 mirrors (or one mirror and a friend)
  • Comb
  • Hair clip
  • 1 to 2 bags of wefted human hair
  • Scissors
  • Latex bonding glue
  • Hair shaper

  1. 1

    Separate the section of hair at the nape of your neck with a fine-tooth comb. Make sure the part is straight. Secure the rest of your hair out of the way with a clip.

  2. 2

    Measure the length of the part above the section you just separated. Cut the seam at the top of the weft of extension hair to the correct length (do not cut the hair).

  3. 3

    Apply a thin stripe of latex hair glue to the seam of the extension weft. Wait 20 seconds, then carefully press the seam onto your sectioned hair near the scalp. The weft hair should lie in the same direction as your natural hair growth. Hold for 30 seconds to allow the bond to form.

  4. 4

    Continue to section your hair in tiers, adding a weft of hair at each layer, until you reach the crown of your head. Make sure all bonds are concealed by a layer of your natural hair.

  5. 5

    Gently razor the ends of the extensions so that they blend seamlessly with your natural hair.

Tips and warnings

  • If you don't have a second mirror that allows you to see the back of your head, or if you're just not comfortable installing the wefts in the back of your own head, ask a friend to help you.
  • The amount of extension hair you use will depend on the thickness of your natural hair. If your hair is very thick, you may need 2 full bags of hair.
  • Take good care of your extensions and they'll last longer. Wash with shampoo in lukewarm water, followed by a moisture-intensive conditioner on the ends of the hair only. Brush the hair gently by section, and braid or ponytail it before going to bed.
  • It's natural for the bonds to loosen over time and after several washes. If this happens, simply reapply a bit of the latex glue and press the bond back into place.
  • Make sure that you're using latex bonding glue specifically designed for hair extensions. Any other kind of glue may damage your hair irreparably.
  • Do not apply glue directly to scalp.
  • Colouring and perming your extensions is not recommended, as the hair has already been processed for colour and texture. You may style your hair with heat, but do not apply heat directly to the bonded areas.
