Hair extensions: what to know

What the job involves, what changes the price, and what to ask a pro.

What hair extensions is

A hair extension specialist adds length or volume to natural hair using clip-in, tape-in, sew-in, fusion or micro-link methods. The right method depends on your hair, your scalp and how long you want the extensions to stay in.

Signs you need it

  • You want longer hair for a wedding, a photo shoot or a special event
  • Your hair is thin in some areas and you want more volume
  • You want a temporary change in length or color without a long commitment
  • You want a method that suits your hair texture, such as a sew-in for thick or curly hair
  • You want a fitting and a plan for how to care for the extensions

What the pro does

  • Looks at your hair, scalp, density and texture to pick a suitable method
  • Matches the extension hair to your color, texture and length
  • Preps your hair by washing, detangling and checking for any scalp issues
  • Attaches the extensions using the chosen method, with careful placement and tension
  • Blends the extensions with your natural hair and styles the result
  • Shows you how to wash, brush and care for the extensions to keep them in good shape

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • The method, such as clip-in, tape-in, sew-in, fusion or micro-link
  • The amount of hair needed for the length and the volume you want
  • The quality and type of extension hair, and whether you supply it
  • How long the application takes and whether it needs one visit or several
  • Whether a fitting, color match or removal is included
  • Whether maintenance visits are needed to keep the extensions in place

What a written quote should spell out

  • The method, the amount of hair and the type of extension hair used
  • Whether color matching, cutting and styling are included
  • The fitting and removal terms, and whether they are separate
  • The maintenance schedule and whether maintenance visits are included
  • The cancellation and late arrival terms

Questions to ask before you hire

  • Which method do you recommend for my hair type, and why?
  • What type of extension hair do you use, and how was it made?
  • How long will the extensions last, and how often do they need maintenance?
  • How do you avoid tension that could damage my natural hair?
  • Can I see photos of extensions you have placed on hair like mine?
  • What is your plan for removing the extensions safely?
  • What should I do if the extensions feel loose or tangle?

Red flags

  • Recommends a method that will pull hard on fragile or thinning hair with no check
  • Will not say what type of extension hair they use
  • Skips the fitting or does not check your scalp before application
  • Promises the extensions will last with no maintenance or care
  • No written terms for removal, maintenance or damage to natural hair

What you can do yourself

You can care for extensions at home with gentle washing, light detangling and the care steps your specialist gives you. Dry the roots and any bonds or attachment points fully after washing, and use a wide-tooth comb. Hire a specialist for any placement, fusion, micro-link or sew-in work, and for removal, because poor placement and removal can damage natural hair.

Licenses and permits

Hair extension work is commonly covered by state cosmetology rules, and most states require a cosmetology license for paid hair work, including extensions. Check with your state's cosmetology or licensing board, and ask the specialist how they are licensed and trained for the method you want.

Hair extensions questions

Which extension method is safest for my hair?

The safest method depends on your hair type, density and scalp. Ask the specialist to explain the options, the pulling risk of each, and the care plan. Avoid any method that feels tight or painful.

How long do extensions last?

It depends on the method, your hair growth and how you care for the extensions. Ask the specialist for a timeline for your method, and book maintenance as they advise.

Can extensions be used with color or heat styling?

Ask first. Many extensions can be colored or heat styled, but the type of hair matters. Tell the specialist about your styling habits before the appointment.
