Add deep black length and extra fullness with our #1 Jet Black 20 Inch Remy Hair Weft Extensions. This approximately 125g Double-Wefted Hair Weft is made from Cuticle Correct Chinese Remy human hair and measures approximately 55–60 inches across.
At approximately 20 inches / 51cm in length, this Hair Weft provides additional length alongside extra thickness. The hair has a naturally straight texture with some natural body and is supplied on a machine-wefted construction for use with suitable Hair Weft fitting techniques.
#1 Jet Black is the deepest true-black shade in our colour range. It is darker than #1B Off Black and considerably deeper than #2 Dark Brown, making it most suited to hair with a strong true-black appearance.
Hair wefts offer flexibility when choosing an application technique. The fitting method should be selected according to the natural hair, required placement and desired result.
Professional fitting is recommended for semi-permanent Hair Weft methods so the most appropriate technique and amount of extension hair can be selected for the natural hair.
View our Hair Weaving Techniques Guide for further information about different Hair Weft application methods.
Hair Wefts may be divided into smaller sections where required for the chosen fitting technique and placement.
When cutting a Hair 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 machine-weft construction and has a naturally straight texture with some natural body. 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 51cm long, a 20 inch Hair Weft provides more length than the 18 inch option while still offering flexibility for adding additional fullness throughout the hair.
This shade contains approximately 125g of extension hair across a weft measuring approximately 55–60 inches wide. 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-extension colour range.
Compared with #1B Off Black, #1 Jet Black has a stronger true-black appearance. #1B is slightly softer and can show subtle brunette depth, particularly in natural daylight.
Compared with #2 Dark Brown, #1 is considerably darker. #2 is clearly within the brunette colour family, whereas #1 remains a deep true black.
If your natural hair appears black indoors but shows noticeable brunette tones in daylight, it is worth comparing #1B Off Black before choosing #1 Jet Black.
For the best colour comparison, check the extension against the mid-lengths and ends of the natural hair in good natural daylight rather than matching only against the roots.
