(1)Advantages of Pre-bonded Hair Extensions: Natural look, durability and versatility. They blend seamlessly with natural hair, have concealed bond points and are suitable for adding length, volume or highlights. Pre-bonded extensions are lightweight and comfortable, require minimal daily maintenance and can be reused if carefully removed. In addition, the keratin bond is resistant to humidity and water, ensuring they remain in good condition in a variety of environments.
(2)Disadvantages of Pre-bonded Extensions: Installation takes a long time, usually 3-5 hours, and can be costly due to material expenses and professional application. Using heat to melt the bond can cause heat damage to natural hair, especially if not applied correctly. Although the extensions are lightweight, the bond adds weight to the hair and may cause discomfort for those with fine or thin hair. In addition, pre-bonded extensions require regular maintenance and the removal process is complicated and should be done by a professional to avoid damaging natural hair. This method may not be ideal for very fragile or damaged hair.
