Tape-In Hair Extensions

The "sandwich" method: your natural hair is gently sealed between two adhesive tape bands. Done right, it sits flat and virtually disappears.

  • Standard tape — classic, ideal for medium to thick hair
  • Pro tape — a thin layer of hair covers the tape for a nearly invisible seam
  • Invisible tape — skin-like flexible tape, best for thin or fine hair
Applying invisible tape? Attach it to the upper part of the hair section only. Applying it to the lower part can cause the hair to mat and slip out of the tape over time.
Pros
  • Safest method available — no heat, glue or tools touch your natural hair directly
  • Natural movement and shine that blends seamlessly with your own hair
  • Fully reversible, with no damage when applied and removed correctly
  • Relatively quick to apply — a full head usually takes under an hour
  • Comfortable to wear, lies flat close to the scalp
Cons
  • Reapplication needed every 6–10 weeks
  • Should be applied by a professional stylist
  • Less ideal for very oily scalps
  • Needs consistent care with extension-specific hair care products
Our pick: her flow — 100% Remy hair, 24 shades, full color-matching support. Tape-in is also available from other brands in our store. Shop her flow tape-in →

Keratin Bond Hair Extensions

Small sections of hair are fused to your natural hair one bond at a time, using a heated keratin tip. Because each bond is tiny, it sits close to the scalp and moves naturally with your own hair — no flat sections, no visible seams.

Pros
  • Very discreet at the root
  • Great for fine or fragile hair
  • Long wear time
Cons
  • Slower to apply and remove
  • Requires a skilled stylist and heat tool
  • Needs consistent care with extension-specific hair care products
Our pick: her flow keratin — same 24 shades as her flow tape-in, so you can mix methods without any color mismatch. Shop her flow keratin →

Weft Hair Extensions

Wide rows of hair are attached to your natural hair using one of two techniques: sewn onto small, flat braids, or secured with the thread-and-bead (micro-bead) method. Because each row covers more hair than a single bond, application is faster per section — making this a strong choice when volume and length are the priority. There's no adhesive involved, so wefts also hold up well to an active lifestyle — the gym, swimming, and everyday movement won't loosen the attachment.

Pros
  • Excellent for volume and thick styles
  • Efficient application per row
  • Holds up well to gym and swimming since there's no adhesive to loosen
Cons
  • Braids or bead rows need periodic upkeep
  • Less suited to very fine or thin hair
  • Requires a skilled stylist
  • Needs consistent care with extension-specific hair care products

No adhesive, no appointment, no commitment. Attach it yourself in minutes, comfortably wear it all day, and take it out whenever you like.

  • Clip-in — individual wefts with small clips, sectioned in at home. The most customizable option and easiest to start with.
  • Flip-in (halo) — one continuous piece worn under a thin, invisible wire. No clips, no glue — just flip your own hair over it. The fastest option and gentle on natural hair.
  • Ponytail — an attachable ponytail that clips or wraps in seconds for instant length and volume — ideal for updos and special occasions.
Pros
  • Zero commitment, no styling appointment needed
  • Reusable
  • Comfortable enough to wear all day
Cons
  • Needs to be removed before sleeping and reapplied each time you wear it
  • Maintenance needs depend on how often you wear it
