The Butterfly Weft Hair Extensions has revolutionized the extension world with its ultra-thin, breathable, and virtually invisible design. It’s the go-to choice for anyone seeking the most natural look. However, because these wefts are engineered to be so incredibly thin, their PU edges are more delicate than traditional options. The good news is that with a few professional adjustments to your routine, you can keep your wefts pristine and durable. In this guide, we’ll walk you through 3 essential steps to protect those edges and maximize the lifespan of your investment.
Why is the Edge Fragile?
Why PU Hole Wefts need extra care: Their ultra-thin design provides unmatched invisibility, but the delicate PU material is more sensitive to tension and oil than standard wefts.
The 3-Step Protection Protocol
Gentle Handling During Washing and Drying
Finger-pad cleaning, avoid rubbing the edges
Emphasize using only your fingertips to gently massage the scalp when washing your hair. Do not pile all your hair on top of your head and rub vigorously, as this will cause unnecessary stress on the PU edges, leading to tearing.
Pressing to absorb water
After washing, use a towel to absorb water by pressing or wrapping the hair. Never rub or roughly scrub the hair and extensions with a towel. In our salon testing, we found that 90% of edge peeling issues were caused by using hair oil directly on the PU band.
Thoroughly dry the extensions
Ensure that the extension area, especially the edges of the PU tape, is 100% completely dry. A damp environment will weaken the strength of the PU material and adhesive, making it more prone to cracking during subsequent brushing.
Special Techniques During Combing Butterfly Weft
- Comb in sections starting from the ends: Always start from the ends of the hair, gently combing out tangles in sections, and gradually work your way up.
- “Support” the extensions while combing: When combing near the PU tape, use your other hand to hold and support the base of the hair extensions (the edge of the extension), isolating the pulling force. This ensures that the pulling force applied by the comb acts on the hair itself, not directly tearing the PU edges.
- Use a dedicated comb: It is recommended to use a wide-toothed comb or soft-bristled brush specifically designed for hair extensions.
Butterfly Weft Protection Before Bed and During Styling
Avoid strong pulling
Before going to bed, loosely braid your hair into a low braid or low ponytail. This prevents hair from tangling during the night, thus avoiding the need to forcefully pull on the PU edges when combing in the morning.
Keep styling tools away from the edges
When using heated styling tools (such as straighteners or curling irons), ensure that the tools do not directly contact the edges of the PU tape. High temperatures can make the PU material brittle or accelerate the decomposition of the adhesive, leading to edge detachment. Keep heat tools below 180°C (350°F) and maintain a 5cm safety distance from the weft.
Changing your pillowcase
We recommend using a silk or satin pillowcase. The smooth surface allows the PU edges to slide smoothly during movement, preventing tiny tears that can lead to cracking.

Pro Tip: Avoid These 3 Common Mistakes
- Mistake 1: Brushing your hair vigorously when it’s wet.
- Mistake 2: Applying conditioner to the attachment points (this will cause the adhesive to fail and detach).
- Mistake 3: Allowing your hair to air dry naturally for extended periods (moisture will penetrate the PU pores and damage the structure).
Butterfly Weft Egde FAQs
