1. Seamless Blend

The ultra-thin PU base with perforations ensures the weft lays flat against your scalp, blending effortlessly with natural hair for a virtually invisible extension line.

2. Comfortable & Irritation-Free

The unique design eliminates bulkiness and discomfort from short return hairs, providing a smoother, more comfortable experience.

3. Effortless Installation

Pre-punched invisible holes make for quick and easy application without the need for adhesives or chemicals. For best results, we recommend using micro-rings and extension tools to ensure a secure and seamless fit.

4. Dual Layer Design Advantage

This weft features a dual-layer design:

• One side has perforated PU for attaching hair with micro-rings, ensuring a secure and invisible fit.
• The other side has smooth PU, with the hair machine-inserted for a more discreet look, perfectly hiding the extension line.

This design not only makes installation easier but also delivers a more natural, seamless extension effect.

5. Customizable & Versatile

Unlike traditional hand-tied wefts, this weft can be easily cut without shedding, offering endless styling possibilities and customization.

6. Long-Lasting

With proper care, this product can last 6-12 months while maintaining softness and shine.

7. Styling Freedom

You can curl, straighten, or dye the hair, but bleaching is not recommended.

1. Prep Your Hair

Start by sectioning your hair and securely pinning the top layer out of the way.

2. Open the Weft

Gently unfold the XO Invisible Weft like butterfly wings. Position it just below your part, with the side with holes facing down.

3. Secure the Weft

Pull two strands of your natural hair through each hole in the weft, then combine them and secure with a micro-ring. Make sure all holes are used for an even, secure fit.

4. Release and Style

Once the weft is securely in place, release the top layer of hair. Your seamless, voluminous look is complete!

Let us walk you through the easy steps to install👇

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!
