Genius weft hair extensions and hand tied weft are very similar, they are a good substitute for each other. It is the same as hand-tied weft, which is very thin, but Genius Weft has the advantage over hand-tied weft that it can be cut at will and has no back hair.

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

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”.

Absolutely blown away!!!

I love the ease of being able to transition between styles without a ton of effort. This product is amazing quality!


I follow Dante on social media and they suggested these. I Host a podcast and sometimes like to add some length to my hair. I got these because I loved how Dante's hair looked. I have to say I was surprised by the price and how nice these are. I highly recommend it.

Very Natural Looking

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!

Soft and Silky!

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!
