Everything You Need to Know About Hair Wefts - Focus on the Invisible Genius Weft
Invisible, protective, and fully customizable — the hair weft is making a strong comeback with a modern twist.
Gone are the days of thick wefts, visible seams, and uncomfortable installs. Today, this timeless technique is winning over a new generation, thanks to innovations like the Genius Weft — an ultra-thin hair weft that combines discretion, lightness, and unmatched comfort.
In this complete guide, RH Excellence shares everything you need to know about the technique, its benefits, its variations, and most importantly, why the Genius Weft is a true game changer in the world of weft extensions.
What is a hair weft?
A hair weft is a hair extension method that involves attaching wefts of hair (bundles sewn onto a textile or silicone band) to natural hair by stitching them securely onto braids or with micro-beads.
A bit of history
Originating within Afro-descendant communities, the art of hair weaving began as a way to care for, protect, and express identity through hair. Popularized in the U.S. during the 1960s and 1970s, the technique has evolved into a professional and highly versatile method used in salons worldwide — suitable for all hair types.
A versatile solution
- Protects natural hair by minimizing manipulation
- No glue or heat required for installation
- Offers complete styling freedom (length, texture, and color)
- Long-lasting results — typically 4 to 8 weeks depending on the method and maintenance
- Can be repositioned and reused
Open vs. closed hair weft: what’s the difference?
Open vs. closed technique
The type of hair weft used plays a key role in both comfort and the overall aesthetic result.
Open hair weft
An open hair weft installation involves attaching the wefts only on a specific area of the head — usually at the back. This technique allows a mix of extensions and natural hair for a seamless, natural look. For example, you can install the weft on half of the head while leaving natural hair visible on the other half, or simply create an opening for a middle or side part. Sufficient hair length is required to properly conceal the weft and achieve a natural result.
The Genius Weft belongs to this new generation of ultra-thin, cuttable wefts — offering maximum invisibility and comfort.
Closed hair weft
A closed hair weft covers the entire scalp. It’s a more traditional approach, often divided into two versions: the classic closed weft and the closed weft with closure.
Classic closed weft
This technique involves braiding the entire head into fine cornrows. Hair extensions are then sewn directly onto these braids, covering the whole head — though a parting can still be created in the center or on the side.
Closed weft with closure
This version consists of sewing the wefts on fine braids at the back and sides, then adding a closure piece at the front to complete the hairstyle. The result is particularly natural and realistic.
Why choose a hair weft? 5 key benefits for your hair

- Custom volume — easily adjust the density
- Versatile styling — wear your hair down, tied up, or braided

How much does a hair weft installation cost?
In salons, a hair weft installation typically costs between €100 and €300 depending on the salon, technique, and number of wefts. The Genius Weft, being more technical and premium, is priced higher — justified by its exceptional quality and durability.
How long does a hair weft last?
The longevity of a hair weft depends on the method used, maintenance, and the weft quality. On average, a well-installed weft lasts between 4 and 8 weeks. After that, removal is recommended to maintain scalp health and avoid tangling at the roots.
