Features of Flat Silk Weft

Flat silk weft combines the best of both worlds in machine and hand-tied wefts to give you long-lasting comfort and ultimate customization.
  • Ultra-thin and Customizable: As thin as hand tied weft and can be cut freely without shedding, which is ultra-thin which is 30% thinner than common wefts.
  • No Tangle, No Knotted: Silk solidifies the weft firmly, strong and won't tangle easily. To avoid hair shedding problem, manufacturers add double-stitched to make it firmer. And it's the least damaging type of hair extensions.
  • Flat and Comfortable: There is a piece of silk attached to the top of the weft, which is extremely flat and flexible silk and no return short hair on the top, more comfortable on the head, not as bulky as the machine weft.

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.

    Why is my hair getting tangled?

    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.


    Generally, we recommend 100g-150g for a full head. If you want thicker hair, around 200g will do. In addition, you can also match different hair extensions, such as topper & clip ins &halo hair.
