How Many Packs Hair Weft Do I Need?

Choosing the right amount of hair is the difference between a high-fashion transformation and a thin, unnatural look. Unlike single wefts, Double Wefts provide twice the density per track, making them the ultimate choice for volume seekers. But how much is “enough”? Whether you’re a first-time user or a salon regular, this guide will help you determine the exact weight and number of packs needed to achieve your dream hair goals.

Understanding the Weight: What’s Inside One Pack?

At Full Shine, our standard Double Weft packs typically contain 100 grams of premium Remy human hair. Because the hair is sewn in two layers onto a single track, you get instant fullness.

• 100g (1 Pack): Ideal for adding a subtle “boost” of volume to hair that is already long.
• 200g (2 Packs): The industry standard for a full-head installation.
• 300g (3 Packs): Reserved for the ultimate “Glam” look or blending very thick, blunt natural hair.

Match Your Hair Type: Fine, Medium, or Thick?

Fine to Thin Hair (100g – 150g)

If your natural hair is delicate, less is often more. Overloading fine hair with too many wefts can cause tension on the scalp. One pack (100g) is usually sufficient to add noticeable length and healthy-looking density without the bulk.

Medium Density Hair (150g – 200g)

For most women with “average” thickness, 2 packs (200g) are the sweet spot. This ensures that the transition between your natural hair and the extensions is seamless, especially if you are adding 4 or more inches of length.

Thick or Blunt-Cut Hair (200g – 300g)

Thick hair requires more weight to “hide” the natural ends. If you have a blunt bob or very dense hair, you will need 2.5 to 3 packs to prevent the “mullet effect”—where your natural hair sits like a shelf over the extensions.

Length Matters: Why Longer Extensions Need More Weight

It’s a common misconception that 24″ extensions will look as full as 14″ extensions of the same weight. As the length increases, the hair naturally tapers towards the ends. To maintain a thick, blunt finish from root to tip, we recommend:

• 14”–18”: 100g–150g for a natural look.
• 20”–24”+: 200g–250g to ensure the ends don’t look sparse or “stringy.”

The “Stacking” Strategy: Rows vs. Layers

With Double Wefts, you can achieve massive volume with fewer rows.

• One Row: Best for adding thickness to the back.
• Two Rows: The most common setup for a full-head transformation.
• Stacked Rows: For maximum impact, your stylist can “stack” two wefts on a single row. This concentrates the volume while keeping the rest of your scalp free and breathable.
