I'm INCREDIBLY impressed with the customer service provided and can say with confidence it is the best I have ever received from a brand.
Deirdre K. 4/5 Verified
This hair is perfect from top to bottom! It is extremely soft and thick to ends. The color match was great. I have thin short hair so if you are looking for length I definitely recommend buying the 150g pack for added volume.

Evelyn T. 5/5 Verified
The hair quality is amazing — super soft, healthy, and looks really natural. It blends in beautifully and feels great to wear. The only thing is that the blonde shades run a bit more yellow than they look in the photos. I ended up exchanging mine for a cooler blonde, which worked out perfectly. Overall, very happy with the product and would definitely buy again!
Harper M. 5/5 Verified
Hair extensions are fun to play with, especially when it's real hair. These passed the few testings that I did to verify and these are legit real hair. This means I can put dye on them and it will hold the dye well. Installation was easy enough, and they are plenty soft and feel good in my hair. Once dyed and cut, it was hard to determine my hair from the extensions. Definitely work the cost, very happy with these.
Lauren 5/5 Verified
Most of the hair, once wet and air dried, has a slight body wave. I love this because I have a natural wave and it helps to blend the wefts with my own hair.The tape in wefts are a bit sticky upon arrival. They do stick to each other, and I am not sure how they will perform.
Katie 5/5 Verified
I am shocked!😍😍😍 these extension are by far the best of the best extensions of all...I will be definitely purchase more! Shedding is minimal to nothing...easily installing.. definitely worth the money! And it blends very very well with my own hair! 💕💕💕

After my 1st time washing and hair drying it, it felt and looked like hay straw. I decided to go to my hairdresser. That's when I found out it was due to the way I was hair drying it. I purchased a better suited hairdryer: Revlon All-in-One Detangling, Straightening Brush, styling. Afterwards, my extensions and hair were amazing. They feel just like when I 1st opened it from the box and blend perfectly with my own hair. Went from hating to absolutely loving it.

These extensions blend seamlessly into your hairline. The weft edges, are artfully sewn with scalp resemblance, and can only be detected if up close and personal. They come pre taped to easily peel and stick. I did blow each one with the hairdryer for a better seal. The adhesive is fantastic and does last through many washings. The natural human hair can be styled with any heat tools as if it were your own.
Chloe R. 5/5 Verified
For human hair, quality wise since the price is very affordable. But I definitely would recommend it
Julia 5/5 Verified
Nice color and nice feel. I ordered these to add volume to my hair. I already have thick hair so these are perfect. As other reviews have mentioned if you have thinner hair you may need to order more than one set. These are great quality and I am very happy with them. They are the best extensions I have ordered.
Stephanie C. 4/5 Verified
I love Sunny hair extensions, I’ve tried all of the hair extensions and all of the brands and Sunny is still my fav! Best color options with great prices along with amazing real quality hair, I’ll continue to buy from this company!

Exactly what I needed. Not a ton of hair, but a perfect amount to play with and at an appropriate length. Quality is perfect. Colour is just lovely. Really pleased.

Got 8 packs of #60 platinum, the 8 packs were the perfect amount for my hair! (Super thin) the colour isn’t a perfect match but pretty close, hair quality is super soft!
Sophia 5/5 Verified
Very soft and nice quality. I have not yet tried washing it but i am hopeful it’ll stay nice as it is.
Zoe 5/5 Verified
These extensions were everything I was looking for. Great quality, they are soft and shiny but not too thin. The color, dark brown, is even all throughout. The length is also the same for each piece. I loved that they could be reused. I used this brands extension tape and it worked great. I was able to style with heat protectants without badly damaging the hair. These also can be cut, colored and styled like your own hair.
Madison 4/5 Verified
I only just took them out of the package so I’ve yet to style them but first impressions are really good, I did wash/dry/style one piece and they didn’t get ruined or anything and were still soft thick ect. I think their going to be really good so can’t wait to put them in and style them!!🥰 (I’ve been wearing hair extensions for 12 years so I know what to look for) I would test them out if you’re on the fence!
Chloe 4/5 Verified
From thin stringy hair to GORGEOUS locks that match perfect. Not a sole has said anything but OMG I didn't know your hair was so long, it's always in a messy bun... beautiful hair curls great , feels great!
Lillian D. 4/5 Verified
these extensions are SO GOOD. I got the 20 inch & they’re a perfect length if you want your hair past your boobs. they feel so soft & real, makes my dry dead ends look less noticeable lmao. the light platinum blonde w light ash roots is an almost perfect color match to my hair but once I put them in it wasn’t noticeable
Elizabeth A. 5/5 Verified
the hair is so soft and the color matched my hair perfectly. super easy to put in and I didn’t use all of them but perfect to use again in the future! it made my hair feel super full and soft and I would totally recommend!

WILL DEFINATELY BUY AGAIN!
Ava D. 4/5 Verified
I have been wearing tape ins for a year and I tried these to save time for my hairdresser as I asked her to darken my root. These ten packs were just enough for extra length. Smell great, super soft and luxurious.
Violet B. 4/5 Verified
A few fell out my first shower.. if you hot iron the tapes together it solves the problem. These are amazing quality! I’ve tried a lot of other brands of hair & it’s rare I leave a review. I had to tone then but I will be buying again!
Zoe W. 4/5 Verified
These are beautiful and so soft. These pics do not do it justice. I have a very short hair cut and very thin fine hair so with these being so light I don't have to worry about breakage. I have already taken them out and reused them and they still look new. My only problem is, I thought that I thought I was getting a 20 pc order. I also wish the gave more than 10 PCs of replacement tapes. I get so many compliments on my hair, but I always admit to it being extensions and how easy they are to do and I refer people to order them from Sunnyhair, since they are so inexpensive but excellent quality. A salon will charge anywhere from 500 and up to do this.
Aurora W. 4/5 Verified
20 inch #60 Had to tone my extensions with purple shampoo, they come very golden toned but other than that very happy with these tape in extensions. The thickness and tape strength are great!

Elizabeth P. 5/5
•GREAT EXTENSIONS• I have had these tape ins for two and a half months now and they are still in great condition! I’ve only had to have them moved up once so far.The tape was a huge help because when I went back to the salon to have my extensions moved up, I didn’t have to buy anything. You can color/tone them too. I toned them when I first got them and I use purple shampoo once a week to keep the yellow/gold tones out. The hair is soft and smooth. I curl it and straighten almost every other day and it hasn’t damaged it. I do recommend you get it trimmed every time you have them put it, like natural hair they do get scraggly on the ends. I get compliments on my hair alllll of the time! I definitely recommend!

I purchased the 18in tape in extensions in the color. I used 3 bags because I have short hair. They were easy to install and take out. They dried beautifully after a shower and were easy to style.

I've wore hair extensions for years, I have tried so many brands I feel like I could right a book. I decided to try these and I think I have found what I have been looking for. I have had these in for over 6 weeks and they are as soft and manageable as they were on the first day. No shedding, tapes haven't slipped, they don't look burned on the ends, no split ends, these are really good quality.
Catherine P. 5/5 Verified
The install was easy. It is versatile. It has a nice sheen and matches perfectly to my hair.
