You can hide the wire by placing it under your natural hair, therefore making it easily and perfectly blend with your natural hair.

      What Is Tape In Hair Extensions:

      For people with thin, fine hair, tape-in hair extensions are very suitable for them, because the hair doesn’t combine with lace-weft, but with small tapes that are very thin and about 4cm wide. A set of tape in hair extension includes about 20 small pieces of hair extension. Each piece of hair extension comes with a piece of single or double-sided tape along the base. A piece of your natural hair is sandwiched between two pre-taped extensions. One of the best parts about tape-in hair extensions is that they are invisible and blend seamlessly with your natural hair because the extensions lie completely flat against your head. The entire process of installation would take about one to two hours and is not too time-consuming. The installation process might be a little harder for a beginner, we recommend leave it to a professional stylist.

      tape in hair

      Another best part of tape-in hair extensions is that they are very easy to maintain. Even with the extensions in, you still can shampoo, condition, and style your hair as usual. However, make sure you don’t use alcohol-infused hair care products as it can break down the glue, causing the extension to fall out.

      With proper maintenance, tape-in hair extensions can last between 6-8 weeks. As your hair grows out every six to eight weeks, the tape inches farther away from the root of your natural hair. You need to let your stylist move them up.

      When removing your tape-ins, using an alcohol-based solution or slippery oil is a great way to make sure a seamless removal without ripping your hair out, the alcohol can dilute down the glue and allows extensions to slip right off from your hair with no residue left behind. You need to pay attention to use removal liquid products because they are extremely flammable!!! We recommend you should visit a professional stylist to help you remove your extensions.

          What Is Cold Fusion Hair Extensions:

          There are two different cold fusion methods available on market, micro loop link and micro ring (I-tip) hair extensions. The two methods look very similar, but they are also a little different in applying technique.

          The micro-loop method is more user-friendly to apply human hair extensions than Micro-ring method. On the top of each strand of hair extensions, a plastic loop and tiny copper ring is being attached. A small strand of your natural hair is pulled through the pre-attached copper ring by pulling the plastic loop, then this ring is clamped flat to attach to your natural hair. In the whole process of installing micro-loop hair extensions, just a pair of hair extensions pliers is needed to clamp those copper rings. Although this method is quicker and easier to apply on than micro ring method, it is harder to be maintained. Those tiny rings are pre-attached on each strand of hair extension, which means it is hard to replaced by a new one. This method is not suitable for fine hair, as they are more visible and more prone to slipping.

          micro loop hair extension

          In the Micro-ring method, the hair extensions are used is I-tip hair extensions. Instead of the extensions and rings are pre-attached, they are separate from each other. When installing I-tip hair extensions, a metal pulling loop is required. Once the ring is installed on your hair, the strand of I-tip hair extension is inserted into the ring and clamped flat via a pair of pliers. 

          This method is more invisible and less likely to fall out, as it allows the rings to be clamped flatter. The color of micro rings can be customized, which means you can choose one color best suitable to your hair color. One of the best parts about Micro-ring method is I-tip hair extensions can be re-used with new rings over and over again. For those who wish to wear their hair extensions for many months, this micro ring method is a great option for them.

           Since cold fusion is an individual strand method, it moves a little more naturally. This method is also a great option if you want to add highlights or lowlights on your natural hair. To protect your natural hair from damage, tiny rings are usually made with copper and lined with silicone.

            Hot fusion hair extensions are one of the original forms of hair extensions. They consist of hair strands and keratin bonding materials. The end of each strands are pre-filled with keratin.

            Since your hair is already made from 90% of keratin, a protein compound, this method is actually gentler on the hair than normal glue.

            This method of hair extension will last 3-5 months. The better you treat them, the longer they will last. This includes carefully brushing your hair with a brush dedicated to extensions. Do not overheat with flat iron or curling irons. Wash only 2-3 times a week for best results. In the long run, proper care will make your hair extensions perform better.


            • Fusion hair extensions are firmly fixed to your own hair.
            • Fusion hair is suitable for thick hair / thick hair.


            • keratin glue could cause serious damage.
            • they tend to be visible through fine strands.

            Hair extension methods such as tape-in, cold fusion and hot fusion, all these methods have one same point is they make a strain on your existing strands. We people shed up to about 100 hairs per day, so over time the amount of your natural hair that attaches an individual extension naturally becomes thinner and thinner. If your natural hair becomes too thin, that extension will be too heavy for your existing hair. Your hair can be easily plucked out which is how the wearer of extension end up with bald spots. We recommend you’re better to change your extensions every 2-8 weeks.
