Brazilian Straight Human Hair Weave 8-30 Inch Natural Colour 1B 100g Bundle That Can Be Dyed and Heat Styled for Sew-In Weft Hairstyles
Brazilian Straight Human Hair Weave in Natural 1B Colour from 8 to 30 Inches

This Brazilian straight human hair weave is supplied as a single piece weighing 100g ± 5g in a natural 1B colour. The source describes the hair as soft, not falling off and not knotting, which are the key stated characteristics for a weave that needs to sit neatly through daily wear. Lengths run from 8 to 30 inches, covering short bobs through to long, flowing finishes, and the two-layer mechanism forms part of the construction. Because the hair can be dyed and heat styled, it suits buyers who want to adjust the colour or straighten the finish to match a chosen look. The 1B natural colour is a dark, understated shade that works with many natural hair colours. Each piece is sold individually, so you can decide how many bundles to use based on the length and fullness you want for a sew-in or weft install.
Features and Construction

This section covers what the source states about the hair itself and how each piece is put together. The information is limited to the stated material, the natural 1B colour, the 8-30 inch length range, the 100g ± 5g weight and the two-layer mechanism. No certifications, origin details or performance tests are given.
Material and Build
The product is made from human hair in a Brazilian straight texture. The source states that it feels soft, does not fall off and does not knot; these are the supplied characteristics rather than results from independent testing. A two-layer mechanism is used in the construction, which relates to how the weft is formed. Each piece is listed at 100g ± 5g, so the weight is consistent per piece within that stated range. The hair is described as able to be dyed and heat styled, which gives flexibility when matching a shade or smoothing the straight finish. The natural 1B colour keeps the overall look dark and understated.
Size and Practical Fit
Lengths available are 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28 and 30 inches. That range allows a shorter length for a bob or shoulder-length style and a longer length for a fuller, flowing finish. Because each piece weighs 100g ± 5g, the volume per bundle is known, and the number of pieces needed will depend on the chosen length and the desired fullness. The straight texture means the hair hangs in a smooth line, and the natural 1B colour blends with dark natural shades. The two-layer mechanism supports a fuller weft when the hair is installed.
Uses and Placement

This weave is suited to sew-in and weft-based hairstyles where a straight texture and a natural dark shade are wanted. The source does not name specific events or professions, so the guidance below stays close to the stated use of dyeing, heat styling and the available lengths.
Event or Professional Use
For occasions that call for a longer or fuller straight style, the 18 to 30 inch lengths offer more hair to work with. The 1B natural colour keeps the finish understated, and the hair can be heat styled so the straight texture can be smoothed as needed. Because the hair can be dyed, a shade can be adjusted to suit a particular look. Each piece is 100g ± 5g, so several pieces may be used together to build volume for an event style. The two-layer mechanism is part of the construction that supports the weft when installed.
Everyday Home Use
For everyday wear, the shorter 8 to 16 inch lengths offer a more manageable straight style. The source states the hair does not fall off and does not knot and feels soft, which are the practical traits it brings to daily use. The natural 1B colour needs no colour adjustment if a dark shade is wanted, and the hair can be heat styled to tidy the straight finish. Each piece is 100g ± 5g, so a single piece can be used for a lighter install or combined for more fullness. The two-layer mechanism supports the weft during wear.
Benefits and Buying Value
The value here comes from the stated human hair material, the 8-30 inch length choice, the 100g ± 5g piece weight, the 1B natural colour and the ability to dye and heat style. The source does not give price comparisons, longevity claims or care instructions, so those points are not invented below.
Reuse and Low Maintenance
The source states the hair does not fall off and does not knot and feels soft. Those are the stated traits that support everyday handling, and the hair can be dyed and heat styled so the finish can be adjusted rather than replaced. No specific washing routine, product list or reuse lifespan is given, so only general human hair care applies. The 1B natural colour is a dark shade that does not require colouring if that tone is wanted. Each piece is 100g ± 5g, which makes it straightforward to plan how much hair is needed.
Why Choose This Product

The source does not provide certifications, origin details or performance ratings, so this description stays within the stated facts.
