Virgin hair is the epitome of natural beauty - it is unprocessed, chemical-free human hair that is truly pure. This means that when you purchase virgin hair, you are getting hair that has not undergone any kind of chemical treatment. It has not been permed, colored, dyed, bleached, blow-dried or subjected to any other chemical process that can harm its natural texture and shine.
  • What makes virgin hair even more special is that it is sourced from a single donor. Each bundle of virgin hair that you purchase should come from the same donor, who could be from India, Malaysia, Brazil or any other region of the world. This means that the hair has not been exposed to any harsh agents or chemicals, and its cuticles are all intact and running in the same direction.
  • Choosing virgin hair is a way to embrace your natural beauty and enhance your unique style. With its pure, unprocessed nature and exceptional quality, virgin hair is the perfect choice for anyone who wants to look and feel their best. So why settle for anything less? Choose virgin hair and experience the beauty and luxury that only nature can provide.

Why Choose Genius Weft?

genius weft hair extensions

1. Very Thin

The overall weft thickness is the same as hand tied weft extensions, very thin, no more than 0.7mm. Therefore it will be very invisible and flat after installation and very hair friendly.

2. Can be Cut

Breaking the restriction that hand tied hair weft cannot be cut, genius weft can be cut at will and no hair will fall out. Installation is more flexible, you can install it to the thinning hair area.

3. No Return Hair

Genius weft hair extensions are not woven by hand, so there is no need to knot the hair on the weft, so there is no return hair, avoiding return hair contacting the hair and causing allergy or itchy symptoms.

Tips for Wearing Hair Weft Extensions

  • Connect your wefts with micro loops
  • Should be completely dry when installed 
  • Start at the edge and weave to the middle
  • Can be glued to your hair weft (allergy test required)
  • It can also be worn by sewing the clips to the weft and then cutting them to different widths as needed.

I recommend!!

I’ve been buying a version of this since 2020. Lots of different ones. Gradually going up in length. I’ve never had one so bluntly cut at the bottom. Some may like that. I prefer it to be more natural and wispy at the ends. To me it looks more natural and “lived in”.

Very soft!

I’ve been using extensions for about 5 months now. These have been the best brand I’ve purchased!! I take good care of them too as I’ve done a lot of research about proper care before even taping them in. I only wash my hair twice a week, use heat protectant tools, they’re in braids when I sleep. These are great quality, the others I’ve used have dried out so quickly and became a pain to manage. I’ve had no issues with these. They just feel like my real hair, so much so, I forget they’re extensions! Haha. They’re light too! Look great. Match beautifully. Thank you!!! Oh yeah!! And customer service is great. 1/2 of the packages sent were the wrong color and they were immediately replaced. Thank you!

Beautiful and easy!

I am obsessed with mine. I bought the 16in for more thickness and then the 20 in for length. I wear them all the time. Super comfortable, easy install, several different ways to style, I highly recommend.

Love these extensions!

The Quality This hair is beyond compare! They are shiny and long. Tangle free and come with extra tapes. So soft and shiny!!! They brush well with no shedding. I love the blend of color. It matches my hair perfectly. They are good quality and are lightweight. One to two packs is enough for fine, low density hair. I love that they stand by their product with a 1 yr warranty also. That's amazing. Not many hair companies do that! Worth every penny!

Affordable and beautiful hair!
