Customer questions & Answers

Q1: What is the difference between U-tip and I-tip?

A: In fact, I-tip Keratin hair extensions is one of the newest extension application systems giving excellent results. Firstly, I-Tip extensions are made up of several hair strands glued together at the tip. Unlike U-tip, I-tip is applied without the use of heat or glue. Secondly, apllying U-Tip is also called “hot fusion” due to the process of heat used to attach each extension. In other hand, I-Tip extensions are attached to the hair by using micro rings. The micro ring is then compressed around the hair for a comfortable secure attachment. This method takes approximately 2-3 hours to install a full head of hair extensions.

Q2: What are Hot fusion and Cold fusion?

A: First of all, hot fusion and cold fusion are the strand by strand hair extension method utilizing approximately 20 – 40 strands of hair, attached together at one end using a glue bond/keratin. However, there are some differences between them as follow:

Hot fusion uses a heating element to attach hair extensions into your hair. Hot fusion refers to U-tip, V-tip, or flat tip. Your hair is placed between the U-tip and sealed with a hot extension tool which melts the Keratin glue which is rolled into the hair. The best bonds are attached close to the root allowing for a little space for movement.
Cold fusion refers to I-tip, which is made up of several hair strands glued together at the tip. Unlike hot fusion, the I-Tip is applied using a pulling tool, whereby an equal amount of hair is pulled through the micro ring to the hairline using a hook tool without using any heat. The micro ring is then compressed around the hair for a comfortable secure attachment.

Q3: Is it impossible for me to bathe, shower, swim, go out in the wind and rain, and play sports with my new keratin tip human hair extensions?

A: Your new hair will look wet as real hair does, and the extension will not show in water. So, you can wash and style your extensions exactly as you do like your own hair. However, exposing to water a lot will loosen bonding though-so dry carefully after. If you swim a lot, I recommend you wear a swim cap.

I have been using human hair extensions for years and was a stylist for the past 10 years. I am impressed with the quality of the product of Sunny Hair Vietnam. I like that it also gave little care instructions with each shipment. The color I received is exactly what I expected. I haven’t had any problems with shedding which is amazing because my scalp tends to sweat and get oily especially during the summer with how active I am. I installed these extensions 3 days ago and am happy with the wear I have been getting. No issues with washing, styling, tangling.

This was my first time trying the human hair extensions. This hair is gorgeous and so soft. I have pretty hair and my hair hair blended very well with these Flat Keratin Tip Curly hair extensions. People could not tell I had them in because they look super natural. I'm going to purchase more today for my next install. I do not know how long they will last but so far I have had them on three weeks with NO issues, girls!!! Sunny Hair Vietnam is the best! Thanks!

I have been doing fusion extensions for years now on my own hair and these are really good. I ordered two packs of the black. They arrived on time but they did not match my exact hair color. I was nervous to dye them but they took AMAZING to the hair dye. I dyed it into black brown color. Now I have very thick hair and 2 packs was enough to do a full head of extensions. I may buy one more just to fill it in further but 2 packs should be enough if your hair is not crazy thick.
