Add deep black length and extra fullness with our #1 Jet Black 18 Inch Remy Hair Weft Extensions. This approximately 120g Double-Wefted piece is made from Cuticle Correct Chinese Remy human hair and measures approximately 55–60 inches across.
At approximately 18 inches / 46cm in length, this continuous Hair Weft provides noticeably more length than our 14 inch option while retaining the flexibility to customise the weft according to the chosen fitting method and required placement.
#1 Jet Black is the deepest true-black shade in our colour range. It is darker and more definite than #1B Off Black, making it useful to compare with naturally very dark or true-black hair.
Hair wefts can be used with several fitting techniques depending on the natural hair, desired result and preferred application method. Suitable professional techniques can include sewn or woven applications, micro-ring methods, compatible hair-extension adhesive, or adapting the weft into removable clip-in sections.
The continuous weft can be divided into smaller sections according to the required fitting pattern and placement. Professional fitting is recommended for semi-permanent Hair Weft methods so the technique and amount of extension hair can be selected appropriately for the natural hair.
View our Hair Weaving Techniques Guide for further information about different Hair Weft application methods.
The approximately 55–60 inch continuous weft can be cut into smaller sections where required to suit the chosen fitting technique and placement around the head.
If you plan to cut the weft, we recommend using our HairX Pro Weft Sealer on the freshly cut edge as directed to help secure and finish the cut section before fitting.
This Hair Weft is made from Chinese Remy human hair with Cuticle Correct construction, meaning the hair strands are arranged with their cuticles running in the same direction.
The hair is supplied on a Double-Wefted construction. As the extensions are made from human hair, they can be washed and styled when required using suitable hair-extension products and styling techniques.
At approximately 46cm long, an 18 inch Hair Weft provides a noticeable increase in length while also allowing extra fullness to be added throughout the hair. It sits between shorter volume-focused wefts and the longer lengths available within the range.
The approximately 120g of extension hair is supplied across one continuous 55–60 inch weft, providing flexibility when planning the fitting layout. The finished result will depend on the natural hair's thickness, density and existing length.
With correct care and maintenance, these extensions have an approximate wear life of 2–3 months. Handle the hair gently when brushing, washing, drying and styling, paying particular attention to the weft and attachment area.
If using heated styling tools, apply a suitable heat-protection product and avoid excessive temperatures. Keep direct heat away from any adhesive, rings, stitching or other attachment points used to secure the weft.

#1 Jet Black is the deepest true-black shade in our Hair Weft colour range.
Compared with #1B Off Black, #1 Jet Black is darker and more definite. #1B has a softer black appearance that can show subtle brunette or brown depth in natural daylight, whereas #1 remains a stronger true black.
Compared with #2 Dark Brown, #1 Jet Black is considerably darker. #2 has a clearly brunette appearance, whereas #1 remains distinctly black.
If your natural hair appears extremely dark indoors but shows noticeable brunette or brown tones in natural daylight, it may also be worth comparing #1B Off Black before choosing #1 Jet Black.
For the best colour comparison, check the shade against the mid-lengths and ends of your natural hair in good natural daylight rather than matching only against the roots.
