    1. How do clip-in hair extensions work?

Clip-in hair extensions are a type of temporary hair extension that can be easily clipped onto natural hair without any tools or professional help. The process typically involves sectioning off a layer of natural hair, teasing the roots to create a base, and then clipping the hair extensions onto the teased section, starting at the bottom and working up towards the crown. One potential advantage of these extensions is that they can be easily removed and reused, and generally last up to a year with proper care and maintenance.

    2. How do sew-in hair extensions work?

Sew-in hair extensions, also known as weaves, are a type of hair extension that is sewn onto braided natural hair using a needle and thread. The process involves braiding the natural hair in a specific pattern, cutting and sewing hair wefts onto the braids, and then styling the hair to blend the natural hair with the extensions.

They are a popular choice for those who wish to experiment with a new hairstyle but avoid the use of harsh chemicals and adhesives. Depending on how well they are maintained and how quickly the natural hair grows, the extensions can last anywhere from a few weeks to a few months.

    3. How do tape-in hair extensions work?

To apply tape-in hair extensions, a special double-sided adhesive tape is used to attach the extension. You’ll need to cut off a small area of your hair, place the extension strip below it, and then sandwich your hair and the strip between two adhesive tapes to complete the operation.

These hair extensions may be reused several times with the right care and maintenance, and they last for around 6 to 8 weeks before they need to be re-taped or adjusted.

    4. How do glue-in hair extensions work?

Glue-in hair extensions, also known as bonded hair extensions, are a type of hair extension that is attached to your own hair with glue and lasts for a few months at most. After removing a section of your own hair and preparing the roots with glue or bonding agent, you may attach the extensions. To prevent damage to the natural hair, glue-in hair extensions should be removed and replaced every 4-8 weeks.

    5. How do fusion hair extensions work?

Fusion hair extensions are a type of hair extension that uses keratin glue and heat to bond the extension to your natural hair. The installation process involves sectioning your hair, placing the extension near the root of your hair, melting the keratin glue using a heat tool, and holding the extension in place until the glue cools and hardens. This type of hair extension should be removed and replaced every 3 to 6 months to prevent harm to natural hair.

    6. How do micro link hair extensions work?

Microlink hair extensions, on the other hand, use small silicone-lined beads to attach the extension to your natural hair. The process involves threading a small section of your natural hair through a micro link bead, inserting the extension into the bead, and crimping the bead with pliers to secure the extension in place. Hair extensions made with micro links should be taken out and replaced every four to six months to protect the health of your own hair.

  • Determine the purpose: Before purchasing hair extensions, decide why you want them. Is it for length, volume, or both? This will help you choose the right type as well as search for how hair extensions work in advance. Each type has its pros and cons, so choose one that suits your needs and lifestyle.
  • Determine the texture: Choose a texture that matches your natural hair. For example, if your hair is straight, opt for straight extensions. If your hair is curly, choose curly extensions.
  • Consider the quality: The quality of hair extensions can vary significantly, so invest in high-quality human hair extensions. They will look more natural and last longer.
  • Read reviews: Before purchasing hair extensions, read reviews from other customers who have purchased the same brand and type of hair extensions. This will help you get an idea of the quality and whether they are suitable for your needs.
  • Consider your budget: Hair extensions can be expensive, so consider your budget before making a purchase. Remember, investing in high-quality extensions will save you money in the long run.


    1. How long do hair extensions last?

The lifespan of the extensions can be affected by how often they are washed, heat-styled, and exposed to environmental factors such as chlorine, salt water, and sunlight. In addition, different hair types often have different longevity, from a few weeks to several months.

    2. Can hair extensions damage natural hair?

Yes, hair extensions can potentially damage natural hair if they are not applied or maintained properly. The weight of the extensions and the tension from braids or clips used to attach them can cause traction alopecia, which is hair loss caused by continuous pulling on the hair follicle. 

Additionally, if the extensions are not properly cleaned or removed, they can cause matting and tangling, leading to breakage and damage to the natural hair. To minimize the risk of damage, you should choose the least damaging extensions and have them applied by a trained professional, and follow a proper maintenance routine.

    3. Can I style my hair with extensions?

Yes, hair extensions can be styled just like natural hair. However, you should notice dos and don’ts while styling your extensions to achieve your desired hair look. Moreover, some types of extensions may have specific care requirements, so keep in mind to follow instructions from a professional stylist.

    4. Do I need a salon to install hair extensions?

It is not necessary to go to a salon to install hair extensions, but it can be helpful to have a professional do it for you, especially if you’re not experienced with extensions. If you’re comfortable doing it yourself, you can purchase clip-in extensions and easily install them at home without any special tools or training.

However, if you’re looking to install more permanent hair extensions, such as sew-in or fusion extensions, it’s recommended to go to a professional stylist who has experience and training in installing extensions. These types of extensions require specialized techniques and tools, and improper installation can lead to damage to your natural hair or scalp. Moreover, despite the higher price, you can also get consulted and purchase hair extensions at salons as they often offer higher hair quality.
