Invisible butterfly weft extensions feature a dual-sided design. One side has a flat and even machine-sewn weft, utilizing advanced injection technology to mimic natural hair growth and create an undetectable realistic effect. The other side features a perforated PU design, which is ultra-thin and lightweight, with no return hair, ensuring comfortable wear and seamless blending with natural hair. It fits snugly against the scalp without appearing bulky. Due to its ability to provide comfort and durability while achieving perfect hair volume, it is highly favored. In this article, we will detail its usage and care methods.
How to install butterfly weft hair extensions?
YoungSee currently offers 9 colors of butterfly weft hair extensions and provides custom options for existing colors on the platform to meet various customer color needs. We have the best-selling solid color blonde #1000, the newly launched highlighted blonde #P8/60, and the popular balayage shade #4/27/4, which are available for immediate purchase.
Step 1: Section the Hair
At the location where the butterfly wefts will be installed, create a clean horizontal part—typically starting from the nape of the neck and moving upwards layer by layer. Use clips to secure the remaining hair, keeping the work area neat and manageable. Proper parting ensures the weft hair extensions lie flat against the scalp and are securely fastened, reducing the risk of slipping, sagging, or displacement. The correct placement of the hair bundles helps the butterfly weft hair extensions adhere smoothly to the head, creating a natural and undetectable effect while ensuring that the hair wefts are durable and comfortable for long-term wear.
Step 2: Measure and Cut the Weft
One major advantage of butterfly weft extensions is their customizable design—you can trim them to any length without worry of them falling apart or fraying. Measure the width of the area where the PU weft hair extensions will be installed and cut or stack them as needed. Our butterfly wefts come in a length of 40 cm, which meets the needs of most customers.
Step 3: Install Butterfly Weft Hair Extensions with Beads
- Place the Hair Weft: Lay the butterfly wefts flat on the pre-sectioned layer of hair. Use clips to secure both ends of the wefts to prevent movement during installation, ensuring even alignment.
- Use the Hook Needle to Pull Through Hair: Take a small amount of natural hair, place the hair wefts on top, and use the hook needle to pull the natural hair through the PU hole. Be careful not to take too little hair, as insufficient hair may not provide enough support, leading to an unstable installation and discomfort in wear. Conversely, too much hair can make the installation uneven, so it's advisable to seek a professional stylist for installation.
- Secure the Beads: Take the natural hair that has been pulled through and pair it with the corresponding human hair bundles of hair below the weft. Thread a color-matching micro bead through both hair bundles, then use pliers to securely clamp it tight. Repeat this process along the weft track for each hole, ensuring even spacing and tight positioning. It’s recommended to first secure the beads at the first and last PU holes of the weft before installing the remaining sections.
- Blend and Style: If necessary, use thinning shears or blending scissors to mix the natural hair with the extensions. Alternatively, use heat styling tools to create a polished look.

How to Care for Butterfly Weft Hair Extensions?
Refer to the following care methods to maximize the lifespan of your butterfly weft hair extensions and keep them looking beautiful.
1.Daily Care
Regular Brushing:Use a wide-tooth comb to gently brush your hair every morning and evening. Start from the bottom and work your way up, paying special attention to the extension areas.
Avoid Chlorine and Salt Water:When swimming, wear a swim cap or use leave-in conditioner to protect your hair from irritating chemicals and salt water.
Regular Maintenance:Schedule adjustments and care with a professional stylist every 6-8 weeks.
2.Care While Sleeping
Don't Sleep with Wet Hair:Hair is most vulnerable when wet, so avoid sleeping with damp hair as it can worsen the situation. Make sure your hair is dry before bedtime to prevent tangling and breakage.
Use Silk or Satin Pillowcases:Unlike cotton pillowcases, silk and satin pillowcases reduce friction, minimizing the chance of tangling during sleep.
Loose Braids or Ponytails:Before bedtime, secure your hair in a loose ponytail, loose bun, or loose braid. If tying a ponytail, opt for a low side ponytail.
3.Care While Styling
Use Heat Protectant:Always spray heat protectant before using curling irons, straighteners, or hair dryers.
Avoid High Temperatures:Keep styling tools at a temperature below 160°C (320°F) to prevent excessive drying and breakage. Also, avoid concentrating heat in one area for too long; use sectioning to ensure even heat distribution.
Apply Hair Oil or Serum:Use a lightweight serum or Moroccan oil on the mid-lengths and ends of your hair to maintain shine and moisture.
Limit Heat Styling:Try to limit the use of heat styling tools to a few times a week to extend the lifespan of the extensions.
4.Care During Washing
Wash with Lukewarm Water:Avoid hot water, as it can weaken the cuticle and make hair rough.
Use Quality Hair Products:Opt for sulfate-free and alcohol-free shampoos and conditioners, as sulfates strip moisture from the hair, leading to dryness and breakage. Avoid heavy styling products that can lead to product buildup.
Avoid Rubbing:After washing, gently squeeze out excess water and pat dry with a microfiber towel. Avoid vigorous rubbing. Also, minimize the use of hair dryers and allow your hair to air dry naturally.
Brush When Slightly Damp:When the hair is about 70% dry, use a wide-tooth comb to detangle. Always start from the ends and work your way up.
Avoid Over-Washing:It is recommended to wash the extensions once a week.
