Description

Do I need professional installation or can I DIY? Most weft extensions are installed with sew-in or beaded methods. If you’re new to wefts, professional installation is recommended for a more secure, natural-looking result. Will these work with my fine thin hair? Yes, but lighter wefts and careful placement work better for fine hair. Avoid adding too much weight, and choose a method that keeps the weft comfortable and discreet. Can I style these hair extensions with heat tools? Yes. You can straighten or curl them like your own hair. Use a heat protectant and keep tools below 180°C/356°F to help maintain softness. Can I dye or bleach these extensions? We don’t recommend dyeing or bleaching, as chemical processing can dry out the hair or change its texture. Choosing the closest shade is the safer option. How long can these hair extensions be used? Wear time varies with installation and care. With gentle washing, low heat, and proper storage, the hair may be reused for multiple installs.

    • Just purchased so far great quality coming from a professional hairstylist
Color: 1-A-#2/8/2 Dark Brown Balayage Size: 18 Inch (Pack of 1)

Update: I used the butterfly wefts even through my summer vacation and I was surfing and doing a lot of workouts in Costa Rica. I purchased the wefts to sew in again it’s more comfortable for me and these are amazing quality. I came back to this company now a second install and I’m really happy with the quality. The hair really pulled through it’s great. My natural hair is at my shoulders - here I used 3 packs and has some left over. 20” and 24” this is a pic right after install (the straight hair) First review: Really nice quality was really easy to install and I did it myself. I doubled the WEST to give it more of a thicker appearance overall so good it washes well curls. Well blow dry nicely will update in two months. I ordered three different webs. I ordered one dark left and two balayage highlighted Wes to blend them together to look and match my own hair and then I sew them together to have that layered colic highlighted. Look to have some color variation. I also ordered three different lengths 1- 24 inch 1- 22 inch and 1- 18 inch. The 18 inch I installed at the top and I doubled it with one of the 22 and then I added A second row of 24 inch doubled up between the dark brown and the highlighted color and then I added a third row doubling up between the dark color and the highlighted color and then trimmed the ends bluntly to match the shortest piece which ended up being 22 inches that way I had like full hair at the bottom I have a pictured here slightly waived and natural lighting. It blends really nicely with my natural hair color I recently went darker so my own hair will fade out just a little bit to kind of blend in a little bit more but I highly suggest getting three packs if you really wanna have thicker hair and double Down there’s a couple of tutorials on how to use the butterfly wax with just beads. I use those on TikTok or YouTube. It did take time if you can get a friend to do it for you or bring it to a stylist of course that would probably be easier but the nice thing about these as you can actually cut the left and not worry about it shedding which so far it’s held up well I’ve only washed it twice, but it seems to be much better quality than others that I’ve tried on Amazon and around the LA area I wish they made these in a genius weft! ... show more

Great hair ordered many times. I’m going to stay with this brand because the others just are not the quality that this brand gives.

Hair color is nice. The bundles are very thin. Hair quality is good no strange smell. Minimal shedding. Doesn’t really hold a curl unless you use alot of hair spray. Definitely human hair no mixture of synthetic.
