Russian Virgin Cuticle Flat Weft Hair Extensions


1 bundle of wefts per pack

100g | 80cm wide

Lifetime: 1-3 Years according to correct care

The Flat Hand-Tied extensions are a brilliant new weft design that can be cut directly anywhere on the seam without the weft unravelling! They are virtually undetectable, seamless, and super blendable. The track is minuscule compared to machine-made wefts making this option ideal for people with thin to medium hair. The Flat Weft extensions give you the freedom to customize every sew-in hair transformation.

Flat Weft hair extensions are strong and anti-shedding, which means they last a long time when cared for properly. They add length and volume to your natural hair with ease.

These extensions must be installed by a salon professional.

All Alvin Hair products are made with 100% Russian Virgin human hair. Flat weft extensions are made using the highest quality virgin hair in the market, which is our top premium grade hair as the hair cuticles are intact and aligned.
