    1. Clip-in hair extensions

Clip-in hair extensions are an excellent option for temporary transformations. As a general guideline, for a full head of clip-in hair extensions, you will need around 100-150 grams of hair. 

However, if you have very thick hair or want a particularly voluminous look, you may need up to 200 grams of hair. The advantage of clip-ins is that you can experiment with different grams to see which works best for you.

    2. Tape-in hair extensions

Tape-in hair extensions are semi-permanent and require professional application. You will typically need around 40-60 pieces or 100-150 grams of hair for a full head, but again, this can vary depending on your hair thickness and desired look. 

    3. Sew-in hair extensions

Sew-in hair extensions, also known as weaves, are installed by braiding the natural hair and sewing the extensions into the braids. To achieve a seamless blend, you might need 150 to 200 grams of hair extensions. However, individuals with very thick hair might require more grams to achieve the perfect balance.

    4. Fusion hair extensions

Fusion hair extensions involve bonding individual extensions to your natural hair using keratin or a similar adhesive. Since this method provides a long-lasting effect, it is crucial to get the right amount of extensions. Generally, 150 to 200 grams of hair extensions are recommended for fusion methods.

    5. Micro-link hair extensions

Micro-link hair extensions, also known as micro-bead or loop extensions, use small beads to attach the extensions to the natural hair. For micro-link extensions, 100 to 150 grams are usually sufficient for a natural and comfortable result.

Let’s discover some key steps: 

  • Know your natural hair thickness: Measure the thickness of your natural hair. Hair thickness can range from fine to medium to thick. Thicker hair may require more grams of hair extensions to blend seamlessly.
  • Set your hair goals: Decide on the hairstyle you want to achieve. If you aim for added length and volume, you’ll need more hair extensions. If you only want to add volume or highlights, you’ll require fewer extensions.
  • Consult with a professional: Visit a hair extension specialist or a professional hairstylist. They have the expertise to assess your hair, discuss your goals, and recommend the appropriate grams of hair extensions for a natural look.
  • Hair extension type: Different types of hair extensions (e.g., clip-ins, tape-ins, sew-ins) have varying densities. Some may require more grams to achieve the desired effect.
  • Quality of hair extensions: High-quality hair extensions often look more natural and blend better with your natural hair. Cheaper, lower-quality extensions may require more grams to achieve a similar effect.
  • Your budget: Keep in mind that the higher the gram of hair extensions, the more costly the installation. Choose a gram count that fits within your budget while still achieving your desired look.
  • Trial and error: If you are unsure, start with a conservative gram count and see how it looks. You can always add more extensions if needed for better results.


   1. How many grams are needed for full head extensions?

The number of grams required for full head extensions can vary depending on the type and thickness of the hair extensions being used, as well as the natural density and length of the individual’s hair. On average, for tape-in or clip-in extensions, around 100 to 150 grams of hair would be sufficient for a full head installation. For more permanent methods like fusion or micro-bead extensions, 150 to 200 grams may be needed. 

   2. Is 90 grams of hair extensions enough?

Whether 90 grams of hair extensions will do the trick depends on a few things. First, it’s all about the thickness and length of your own hair. Also, the type of extensions you’re using matters. 

Sometimes, 90 grams might be just right for adding some volume or doing a partial head installation. But if you’re going for a full head installation or really want a noticeable boost in length and volume, 90 grams might not be sufficient. 

   3. Is 200 grams of hair enough for a full sew in?

In general, 200 grams should be sufficient to achieve a full and natural-looking sew-in weave. However, we still recommend consulting with a professional hairstylist to ensure the right amount of hair is used, tailored to individual hair types and style preferences. Their expertise will help you achieve the best results for your sew-in hairstyle.

Final thoughts

To sum up, if you ask, “How many grams of hair extensions do I need?”. The answer is generally from 100 to 200 grams. To calculate the required grams of hair extensions, several factors come into play. The length, thickness, and texture of your natural hair, as well as the volume and style you wish to achieve, should all be considered.
