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.

Supper cute it was easy to instal and gave my hair lots of volume

Highly recommend!

I absolutely love this product! I am trying to grow out my hair and wanted to have some extra length in the meantime. It is super easy to install (after watching a few TikTok tutorials lol) and you can barely tell it's there! I was a little hesitant about picking out a color online, but if you take a picture of your hair with flash and compare it to the online colors it makes it super easy to pick. I was shocked on how well it blended with my hair when I first installed it.

I love these because the quality of human hair is top notich. I love how silky they are. I have trimmed some layers in them. When I curl I use heat resistant spry sold here, and some hair spray and curling iron. I took and idea from hair dresser to the stars and since I curl almost to the top (dry if you wash first) and use hair spray for wigs though this is human hair and a blow ddryer because I keep heat low and it does not reach last layers then I clip and let cool the curl will last several days and if need be I use an oil free product all mentioned sold here. I dont use the halo line and use the clips instead. The color is spot on and looks real and goregeous. I am starting on my second set of extensions I bought the 20 inch in chocolate brown and I love these over all I have bought. I have worn synthetic ones before as well as these human hair and these are the best I have found. Barely any shedding. I looked back to my two favorite brands and one is no longer available. However I have had these the longest and they have way outlasted the two year mark. I searched to see the brand and this is it! I wear extensions daily due to septic shock caused some hair loss. I have fine hair and had alot of it. I love the two extra pieces of hair you can use as you want. In total they would make up another row of extension width and length. I use them to the front and curl like extension bangs would be. I have a cut in the middle a row of extensions before and used as a ponytail and clipped them on around my pony. These pieces have clips so that could be done. This is the most grams of human hair for the length I have seen on Amazon. Yes I have shopped online and instore for extensions but I kept coming back to Amazon. I do most all of my shopping on Amazon. I am so pleased with what is offered here for all budgets. I love the sales! Back to the hair: I really like that the manufacturer has best written directions on how to care for them I have ever seen. I highly recommed these so easy to put on in seconds and wa la! You have long luxurious hair. If you get straight it is easy to curl with iron, curlers when wet and let dry. I just use a clothes hanger and clothes pins to hook them on and the clips and rollers I found here. I use products from Amazon for hair extensions, it truly does make a difference especially the heat protectant spray. I have 3 sets of extensions right now and wear them like I did my hair. No one knows. I trade them out and have at the ready some curled the way I want, so I just pop them on and some bangs I bought at Amazon and I am good to go. I use two rows of these, per wear. I used to use 3 rows, but I found I only need two. It all depends on how you are going to wear them, mixed in with the wire and your hair or like I tweaked them to suit me. I highly recommend buying these extensions I got the 22 inch but really the 20 is long enough for me. I am no hair dresser but I love my hair more than ever! For anyone with loss of the hair they had, but have enough to clip on (although I have used the wig caps under) these are ideal!
