I have used clip in extensions on and off for roughly 10 years. I've always bought pretty high quality extensions because they last and maintain quality without excessive maintenance, but they are just so expensive that I ran across these while searching for more cost effective options. Boy, was I nervous/pretty darn pessimistic in every which way. Would they hold? Could they really be easily applied? Would the quality deteriorate after one wash/heat? At this price, it was impossible they would hold up. After paying ~$140.00 for clip ins for YEARS, I could CRY with happiness at these! Here's the breakdown:
1. QUALITY: Upon arrival, they are as high quality as any of the $100+ I've ever bought. There IS a noticeable change in quality the first time after you wash them, but it wasn't breakage or frizz, it was just that they dry a bit wavy on their own. This is an easy fix with a good flatiron.
2. ENDURANCE: I wash my hair every other day with these and am now on week 4 without issue. I am careful with them when I wash in terms of pulling/scrubbing, but otherwise, I've treated them as my own hair without any falling out. Awesome.
3. PRICE: This is a steal. Seriously. I have VERY fine hair and only ordered one pack to start. I could have stopped there and been fine, but did order a second for more volume, partially because it was so cheap that I could afford to order a second pack just to use half of it.
4. APPLICATION: I am by no means any type of beauty professional and I did these DIY. For real. I did watch a few videos to get some tricks that were worthwhile (especially the one where you use a straightener after they are placed to bond better).
5. STYLING: They are not impossible to style, but do require you to do it very small/thin pieces at a time. So, a bit tedious. But style does hold well without hairspray, straight or curly.

The color matches so well! Just got them put in today, so we'll see how well they hold up since the reviews seem mixed about the tape itself that's provided. I bought 3 packs (150g total) and it has a very full look. It's heavy obviously, but my hair is pretty thick as is and so likely you'd only need 2! The hair looks so much like mine I can't even explain, but so far I'm in love!

UPDATE PLEASE READ!!!!! ***I can't say enough about these extensions. I've paid $785 on micro bead extensions which absolutely destroyed my head & hair! I've also used clip ins which are a pain to always put in and take out! These extensions lasted me months! I had them put in by my salon and it took about 30 minutes! You need 2-3 packs. 2 worked great for me but I just placed my second order and this time I'm going to do 3. I high highly recommend these! You can do whatever you want to them! The tape is outstanding and soooo sticky! Plus the pool and ocean water doesn't affect them at all! What I love most about these is you don't even notice they're in! They are super light weight! I use it's a 10 on them when I get out of the shower and brush with a wet brush to make sure there are zero tangles! Also it's best to braid them at night! I got compliments on my hair everywhere I went, you would never know they're extensions! UPDATE: IM SOOOO MAD!!!! I absolutely loved my extensions the first time I ordered them now just repurchased them and they are not the same. Now I have to go through the prprocess of returning them after I just wasted $80! NOW THEY ARENT THE SAME COLOR, CAME IN A DIFFERENT BOX, AND ARENT DOUBLE SIDED! THANKS!

So far I have had the tape ins for almost two weeks and first off, let me start by saying excellent shipping! I received the hair with in 24hrs of ordering. I was a little skeptical of buying hair off amazon because I've always gone to a store and felt the hair and matched it to my own in person but let me say I wouldn't know the difference between this hair and hair bought from the beauty store! The hair was great quality when first received. I was astounded by the quality compared to the 100 dollar set at the beauty stores! In my experience with extensions the hair does lose a little quality when washed and heat but after two washes it's held up very well. I've never used tape ins before and I will never go back to beads or clip ins! It is so comfortable to sleep in, there is a little getting used to with the weight difference and it pulling on your own hair at times (suffice to say I put them in myself). I have had two pieces pull out so far do to brushing when wet (don't do) and to there not being enough hair sandwiches together. All and all I would definitely by this product again and I have and will continue to recommend it to anyone looking into getting extensions!

The hair is excellent quality, I was a little skeptical at first but after reading good reviews I decided to purchase. I've purchased from Glam Seamless in the past (expensive $$$$) and the quality of the hair is very comparable. However, I'm giving 4 stars because the tape that comes attached is an absolute NIGHTMARE. I waited 3 days after application to wash my hair (using proper tape in extension shampoo and conditioner... I'm very experienced with tape ins) and 18 out of the 20 wefts fell out in the shower. The tape completely lost its grip when it became wet. As the water ran through the pieces came right out in my hands and on the shower floor. Not a good experience. I was very disappointed. I would suggest that if you purchase this hair, buy tape from the Glam Seamless website and use that instead of the tape that is provided. With that said, the hair is good quality and even if it's not as long lasting as other brands, the affordable price would allow you to repurchase packs as you need them.
