Butterfly Weft Hair Extensions - Straight - 18 inches - Color 1

Butterfly Weft No. 1 Black: Injected-Hair Weft with Microbeads

Butterfly Weft No. 1 Black is designed to add length and volume to black hair while keeping the attachment thin and discreet. The human hair is injected directly into a flexible polyurethane membrane with no bulky stitching or visible knots.

Measuring only 0.08 mm thick, the weft lies flat against the head. Its 22 pre-punched holes allow the stylist to pull small sections of the client’s natural hair through with a hook tool, then secure the weft with microbeads.

The application is completely heat-free, with no glue, adhesive, or braiding required. When properly installed and covered with enough natural hair, the weft blends discreetly into the hair and feels nearly flat to the touch.

No. 1 Black: A Deep, Even Shade

No. 1 is a deep, even black with no dominant brown undertones. This shade is best suited for naturally very dark hair, black hair, or hair that has been colored a similar shade of black.

These black human hair extensions enhance the fullness of dark hair without creating an obvious color break between the roots and lengths. They can be used to add volume or create a full transformation with 18-inch lengths.

Because black shades can look different depending on lighting, previous color services, and the client’s natural hair texture, always confirm the match with the RH Excellence color ring before ordering. Compare the swatch at the roots, mid-lengths, and ends in natural daylight.

Benefits of a Black Injected-Hair Weft with Microbeads

A Thin Membrane with No Stitched Track

Unlike a traditional weft sewn onto a fabric track, Butterfly Weft uses a polyurethane membrane into which the hair is directly injected. This construction reduces bulk and allows the weft to lie flat when properly positioned.

A Heat-Free, Adhesive-Free Attachment

The weft is mechanically secured with microbeads clamped using extension pliers. No keratin, glue, or tape is applied to the client’s hair. During a move-up appointment, the stylist opens the beads, removes the weft, checks the natural hair, and repositions it.

Even Weight Distribution

The 2.1 oz (60 g) of hair is distributed across a 17-inch (43 cm) weft. This design spreads the weight along the full width instead of concentrating it at only a few attachment points. Comfort and safe wear still depend on appropriate sectioning, correct tension, and the strength of the client’s natural hair.

A Customizable, Cut-to-Fit Weft

The membrane can be cut between the pre-punched holes to fit different areas of the head. The holes are spaced approximately 0.8 inch (2 cm) apart, allowing the stylist to customize the width without fraying or significant shedding.

Butterfly Weft No. 1 Black Specifications

Remy Hair Quality and Expected Lifespan

Butterfly Weft No. 1 is made with professional-grade Remy human hair. The cuticles are preserved and aligned in the same direction to reduce friction and help maintain softness, shine, and smooth movement through the lengths.

The Middle Drawn quality provides balanced density with slightly finer ends, creating a less bulky appearance and making it easier to blend the extensions into the client’s haircut.

With proper care and professionally performed move-ups, the weft can be reused for several months. Its lifespan may reach up to 12 months depending on how often it is worn, styling habits, products used, and compliance with the recommended care routine.

A move-up is generally required every 4 to 6 weeks, depending on the client’s hair growth and how well the microbeads remain secure.

Who Is the Black Butterfly Weft Best Suited For?

This method is designed for clients who want additional length or density without an adhesive attachment or heat-based application. No. 1 is best suited for black hair and very dark bases that match the RH Excellence color ring.

The 2.1 oz (60 g) weft must always be matched to the client’s available density. For fine, fragile, thinning, or breakage-prone hair, a thorough consultation is essential to confirm that the roots can support the weight and that enough natural hair is available to cover the attachment points.

The stylist determines the number of wefts, their width, and their placement based on the client’s starting hair, haircut, and desired result.

How to Install Butterfly Weft No. 1 in 5 Steps

The injected weft and microbead application must be performed by a stylist trained in professional hair extensions. Installation time varies depending on the number of wefts used, the desired density, and the placement plan.

1. Complete the consultation and hair assessment.
   Examine the scalp and evaluate the density, length, and strength of the natural hair. Determine an appropriate weight and confirm No. 1 against the color ring in natural daylight.
2. Create clean sections.
   Make neat horizontal partings, beginning at the nape. Leave enough natural hair around each section to cover the membrane and attachment points.
3. Customize the weft.
   Position Butterfly Weft over the selected section, measure the required width, and cut the membrane only between two pre-punched holes if an adjustment is needed.
4. Secure the weft with microbeads.
   Anchor the ends first, then work toward the center. Use a hook tool to pull a small section of the client’s natural hair through each hole, insert the microbead, and clamp it with professional extension pliers.
5. Check the fit and blend the lengths.
   Make sure the weft lies flat with no excessive tension or discomfort. Finish with the necessary cutting and blending to integrate the black extensions into the client’s natural hair.

How to Care for Black Butterfly Weft Extensions

A consistent care routine helps maintain the softness of the hair and the depth of the black shade throughout repeated use.

• Use a gentle shampoo and products formulated for human hair extensions.
• Apply conditioner or a hair mask only to the mid-lengths and ends, avoiding the membrane and microbeads.
• Detangle gently from the ends upward while supporting the attachment area.
• Rinse thoroughly, then fully dry the roots, membrane, and beads after every wash.
• Never go to bed with wet or damp hair.
• Keep oils, serums, and other rich products away from the attachment points.
• Wear the hair in a loose braid at night to reduce friction and tangling.
• Apply a heat protectant before styling and never exceed 356°F (180°C).
• Protect the lengths from prolonged sun exposure, chlorine, and salt water, as these may affect the appearance of the color.
• Test any color-depositing product on a small section before applying it throughout the extensions.

Butterfly Weft No. 1 Black: Frequently Asked Questions

How Is Butterfly Weft Different from a Traditional Weft?

A traditional weft typically consists of hair sewn onto a fabric track. With Butterfly Weft, the hair is injected without visible knots into a 0.08 mm polyurethane membrane. This creates a thinner edge that lies flatter against the head when properly installed.

What Is the Difference Between No. 1 and No. 1B?

No. 1 is a deeper, more even black. No. 1B is generally considered a natural black that is slightly less intense and may have a softer undertone. Never choose based on the shade name alone; compare both colors with the client’s hair using the RH Excellence color ring.

Can Butterfly Weft Be Applied to Fine Hair?

The width of the membrane helps distribute the weight evenly, but this does not make the method suitable for every client with fine hair. Before installation, the stylist must assess the density, root strength, scalp condition, and the amount of natural hair available to conceal the attachment points.

How Many Wefts Are Needed for a Full Installation?

The quantity depends on the client’s starting density, haircut, and desired transformation. As a general guide:

• 2 wefts, totaling 4.2 oz (120 g), may be suitable for adding length and volume to medium-density hair.
• 3 wefts, totaling 6.3 oz (180 g), may be needed for a fuller transformation or for naturally thick hair.

The final quantity should always be determined during the professional consultation.

How Often Does Butterfly Weft Need a Move-Up?

The weft is generally repositioned every 4 to 6 weeks. The exact schedule may vary based on the client’s natural hair growth, microbead security, and at-home maintenance.

Can No. 1 Extensions Be Colored or Lightened?

Because No. 1 is already a very dark shade, any chemical color service should be approached with caution and preceded by a strand test. Lightening is not recommended, as it may compromise the hair’s softness, integrity, and lifespan. Never apply color or lightener to the polyurethane membrane.

Can the Hair Be Worn Up After Installation?

Yes. Many updos and ponytails are possible when the wefts are placed according to the desired style and enough natural hair is left to cover them. Very high or tightly pulled styles may expose the attachment points or create excessive tension.
