Flat silk wefts are a type of hair extension that combines a silk base with a polyurethane (PU) strip to create a thin and flat weft. These extensions are designed to provide a seamless and natural-looking result when applied to the hair. The flat silk weft combines the advantages of machine weft and hand tied weft. It is not as bulky as the machine weft, and can not be folded as the hand tied weft, but can be cut from anywhere without shedding. It has no return hair on them (the short little hairs that¡¯s normally on top of wefts), so it allows for a natural, very flat and comfortable application.

• Real Human Hair: The extensions can be cut, curled, straightened, dyed or styled as desired, just like your natural hair. However, it is not suitable to bleach, and you can only dye dark colors from light colors.
• Virgin Hair: The virgin hair extensions are made from the same donor. The cuticles are intact and aligned, reducing tangling and breakage. They retain their natural color, texture, and integrity, providing a truly realistic and seamless look.
• Thin and Flat: The flat silk weft is designed to be thin and flat, making it less noticeable and more comfortable to wear. The thinness of the weft allows for a seamless blend with your natural hair, creating a natural and discreet look.
• Customizable and Flexible: Hair weft can be customized to suit your preferences. The wefts can also be cut and layered to create a personalized and natural-looking result.
• No Adhesive or Chemicals: Unlike some other hair extension methods, hair wefts do not require the use of adhesives or chemicals. The wefts are sewn directly onto the braided sections of your natural hair, minimizing the risk of damage or allergic reactions associated with certain bonding agents.

1. Direct Sew-In

This traditional method involves braiding your natural hair into cornrows and sewing the weft onto the braids using a needle and thread.

Pros: Long-lasting, secure hold, no heat or glue involved.

Best for: Thick or coarse hair types seeking a more permanent option.

Maintenance: Every 6–8 weeks.

2. With Micro Rings / Beads

Small silicone-lined rings are used to attach the weft to small sections of your natural hair without heat or glue. The weft is then sewn through the beads for a firm hold.

Pros: Gentle on hair, no glue or heat, reusable.

Best for: All hair types, especially for those wanting a chemical-free method.

Maintenance: Tightening every 6–8 weeks.

3. With Glue / Adhesive

The weft is attached directly to the scalp or hair roots using a special hair-safe bonding glue.

Pros: Quick installation, flat and natural look.

Best for: Temporary use or events.

Caution: May cause damage if not removed properly—professional removal recommended.

4. With Clips

Clip-in wefts come with small, sewn-in clips that can be easily attached and removed at home.

Pros: DIY-friendly, no damage, great for occasional wear.

Best for: Beginners or anyone who wants instant length or volume without commitment.

Maintenance: Remove daily before sleep; wash occasionally.

To help your weft extensions stay stunning and last longer, here are a few simple, yet effective care tips:

1. Gentle Washing – Treat your wefts with care by using a sulfate-free shampoo. Gently cleanse without rubbing to keep them soft and healthy.

2. Proper Drying – Let your extensions air-dry naturally to preserve their texture. If you need to use heat, keep it on a low setting to protect the hair.

3. Careful Brushing – Use a wide-tooth comb or loop brush to gently detangle. Always start from the ends to avoid causing damage to your extensions or natural hair.

4. Nourish with Love – A small amount of argan oil or hair serum applied to the ends will keep them shiny, hydrated, and looking gorgeous.

5. Safe Styling – Always use a heat protectant when styling and keep the heat below 180°C (350°F) to maintain the quality of your extensions.

6. Nighttime Care – Protect your extensions while you sleep by braiding them or using a silk pillowcase to reduce friction and prevent tangling.

With these thoughtful, simple steps, your weft extensions will continue to look fresh, smooth, and natural, making every day a good hair day!
