What is Virgin Hair?
Virgin hair is chemically unprocessed human hair, also known as Pure virgin hair, it has to be 100% pure.
- It cannot have gone through any kind of chemical processing, so when you purchase this hair, it has not been permed, colored treated, dyed, bleached, blow-dried, gone through any other chemical processing.
- It's from one single donor so each bundle you buy should from the same donors(the donor could be Indian, Malaysian, Brazilian, etc). This has not been exposed to any kinds of harsh agents and the cuticles all still have to be intact and running the same direction.

Why Choose Virgin Hair?
- The bundle is usually a single donor.
- The raw material for virgin hair is scarce and high quality.
- The cuticle is completely intact and well aligned (lasts longer).
- Never manipulated by chemicals, dyes, harsh treatments.
-
will match and blend perfectly with most hair types.


Why Choose Genius Weft?
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

This is beautiful hair! Nice thick bundle that is sewn rather well with no short hairs on the base! I'm going to be sewing some clips on here which it actually includes in the box! Very happy with this hair!
I have had many diffrent brand experiences and I was scared to purchase and be disappointed agian so i only purchase 1 pack . When I opened my package I couldn't believe how thick and full the hair was from top to ends . Color was exactly what I expected it to be and I was able to pull it off with just 1 package of hair, ofcourse if I would want fuller thicker hair I would just need half of the 2nd pack! Love these extensions 😍 I totally recommend! Ps. I even went swimming and to the beach and when I washed my hairs dried and styled hair was looked and felt so brand new and silky with no shedding what so ever! ☆☆☆☆☆
Very good, good quality and value for money.
These are really nice extensions, I like to buy a long pack and a short pack for layers. I ended up dying them as you can see and they took the color perfectly and stayed really nice 😊
My new hair was installed yesterday. It generally lasts 4-6 months. I will continue to order from Vivien.
