How Many Grams of Hair Extensions Do You Need?

Are you dreaming of having long, thick, and silky hair, but your natural hair lacks the desired length or volume? Hair extensions can be the perfect solution to transform your look in a short time. However, to achieve the most aesthetically pleasing results while ensuring safety and comfort, it is crucial to accurately determine how many grams of hair extensions you need.

If you use too few extensions, the transformation may be barely noticeable—unless your goal is simply to add slight volume. On the other hand, using too many can put unnecessary pressure on your scalp, potentially causing hair breakage or scalp irritation. Finding the right amount of hair is key to achieving a perfect hairstyle without compromising the health of your natural hair.

This article will help you answer the question: “How many grams of hair extensions do you need for a beautiful, natural-looking, and scalp-friendly result?”

Why Is the Amount of Hair Extensions Important?

• Personalized Analysis Is Key
  Every individual has a different hair type, thickness, and length. An experienced hair extension specialist will assess your natural hair and styling goals to determine the most suitable amount of extensions.
• Desired Outcome: Length, Volume, or Both?
  Depending on whether you’re aiming to increase length, volume, or achieve a full transformation, the required amount of hair will vary.
• Application Method Matters
  Beyond the hair weight, how the extensions are applied and evenly distributed is also essential. A professional stylist ensures the extensions are securely attached, look natural, and feel comfortable to wear.

How to Choose the Right Number of Grams Based on Hair Type

1. Fine or Thin Hair
If your hair is fine and delicate, opt for 60–100g of single-drawn hair (where the ends are thinner, creating a natural taper).

Recommended methods include:

• Microbond Extensions: Lightweight and evenly distributed, reducing stress on the scalp.

• Hand-tied Wefts: Custom-sewn to fit your head size.

• Clip-in Extensions: Easy to attach and remove—ideal for short-term use.

2. Medium Hair
Depending on the desired length:

• 18–20 inches (45–50 cm): Approx. 100g

• 22–24 inches (55–60 cm): 120–150g

• 30 inches (75 cm): 150–180g

Both single-drawn and double-drawn hair can be used, depending on your natural thickness.

3. Thick or Heavy Hair
If your hair is naturally thick, you’ll need more hair to blend evenly:

• Short hair: 100–120g

• Medium length: Minimum 150g

• Long hair (30+ inches): Minimum 200g

For best results, choose double-drawn hair, where around 70–80% of the strands are the same length, ensuring uniform thickness from root to tip.

Estimate Based on Desired Hair Length

The longer the hair, the fewer strands you’ll find per 100g bundle, meaning more grams are required to achieve the desired density.

How Many Grams for a Full-Head Installation?

There is no one-size-fits-all answer as it depends on your hair type, method of installation, and personal preference. However, here are general guidelines:

• 50g: Ideal for adding volume to the crown or temple area.

• 100g: Sufficient for a full head if the desired length is short (16–20 inches).

• 150–200g: Recommended for long hair (26–28 inches).

• 240–300g: Suitable for very thick natural hair or lengths over 80 cm.

⚠️ Important Note: Do not decide the amount of hair on your own. Overloading weak natural hair with too many extensions can cause breakage.

How Many Strands or Bundles Are Enough?

Keratin Bonds (K-tip or I-tip):

• Microbond (0.6–0.8g/strand): About 125–160 strands per 100g

• Nano bond (0.3–0.5g/strand): About 200–330 strands per 100g

Hand-tied Wefts:

• 1 row: For adding volume only

• 2–3 rows: For adding both volume and length

Tape-in Extensions:

• Around 40 tapes per 100g

• Available in 2.5cm and 4cm sizes depending on your styling needs

Clip-in Extensions:

• 3 clips: For subtle volume boost

• 5 clips: Standard full-head coverage

• 7 clips: For very thick hair or more coverage

Other Factors That Influence the Required Hair Weight

• The longer and thicker your desired style, the more grams you will need.

• Do not estimate blindly—consult a professional stylist for the best results.

• Avoid extensions if you are currently experiencing:

  • Significant hair loss

  • Scalp irritation or damage

  • Ongoing medical treatment (e.g., chemotherapy)

Conclusion

Accurately determining the number of grams of hair extensions needed is a crucial factor in achieving a natural-looking, well-balanced hairstyle that is also safe for scalp health. Depending on your natural hair texture, intended purpose (adding length, volume, or both), extension technique, and desired length, you’ll need to select the appropriate amount of hair to ensure the best aesthetic results without damaging your hair roots.

Instead of relying on guesswork or personal intuition, it is highly recommended to consult a professional hair extension specialist. They can provide precise guidance on the type of hair, the exact number of grams required, and the most suitable application method. Making the right decision from the beginning not only helps you achieve your desired look but also ensures safety, comfort, and long-lasting beauty throughout your hair extension experience.
