Description of Hand-tied Weft

Hand-tied weft extensions are known for their ability to create a natural and undetectable appearance which are a type of weft that is hand sewn to give you the thinnest track of hair. Hand-tied hair extensions is that the stylist attaches wefts onto the row of beads by hand-tying the wefts in with cotton or nylon thread, similar to the beaded weft method.  The wefts themselves are carefully crafted by hand, ensuring that they are thin and lay flat against the scalp. This meticulous preparation contributes to the extensions' ability to blend flawlessly with natural hair, making it difficult to distinguish between the wearer's own hair and the extensions.

Features of Hand-tied Weft

  • Thin & Undetectable: The great thing about the fine work of the hand-tying technique is that the seam used to merge your dream hair with yours is thin, allowing the extensions to lay flat against your hair and become one with it, which is lightweight and thin weft seam sought by stylists and clients.
  • Great for Thin Hair: The track on hand-tied extensions is much thinner than machine wefts and is great for thin hair or fine hair, as the weft is lighter and more flexible. It lays close to scalp, flat and flexible, much thinner and not as bulky as a machine weft.
  • Seamless Return & Avoids Tangling: The benefit of using hand-tied hair extensions is that every weft is individually handstitched. They are created with high precision so each weft is very strong and prevents shedding and helps create a perfect blend. That creates a seamless, ultra-thin extension that is virtually undetectable.
  • Can't be Cut: Hand-tied wefts come pre-cut into smaller pieces and should not be cut, as they will unravel and become unusable.

  • Thickness: Thicker compared to hand-tied wefts.
  • Rigidity: Less flexible due to their construction.

what is virgin hair


What is Virgin Hair?

  • Virgin hair is directly taken from the human head and does not undergo any chemical alteration or cleansing process. It has to be 100% pure.
  • It cannot have gone through any kind of chemical processing, so when you purchase this hair, it has not been permed, bleached, blow-dried, gone through any other chemical processing.
  • It's from one single donor, so each bundle you buy should be from the same donors(the donor could be Indian, Malaysian, Brazilian, etc). This has not been exposed to any kinds of harsh agents and the cuticles all still have to be intact and running in the same direction.

    Your hair tangle due to dryness, oil & dirt build-up, saltwater, and not combing (wide tooth comb) out your hair daily.
    Make sure to wash & condition your hair at least once a week, twice a week is better. Use hydrating drops or consult your stylist for more help.
