How To Install & Care For

Installation Steps:


Section hair. Create a clean section where your weft will be placed.

Create a foundation. Choose your preferred foundation method; for instance, we use a beaded method here.

Measure the weft. Align the machine weft with the foundation to measure and determine where to cut the weft.

Sew to the foundation. Attach the weft to the hair by sewing it to the foundation.

Admire the result. Enjoy your undetectable and seamless weft effortlessly blended with your hair.


Care Instructions:


Wash your hair infrequently using a mild shampoo and conditioner designed for hair extensions, avoiding the wefted area.

Use heat styling tools sparingly, with a heat protectant spray to prevent damage.

Avoid sleeping with wet hair, and consider a satin bonnet or pillowcase to minimize tangling.

Refrain from using harsh chemicals or treatments on the extensions.

Regular maintenance with a professional stylist is crucial for extension longevity and a natural look.
