The Ultimate Hair Extension Guide by Kirby Hair & Beauty

Everything You Need to Know Before Getting Hair Extensions

Hair extensions can completely transform your look—adding volume, length, colour, and confidence. But with so many options out there, choosing the right type, length, and amount of extensions can feel overwhelming—especially if you're a first-timer.

At Kirby Hair & Beauty, we believe in educating our clients so they feel informed and excited—not confused—about their hair extension journey. This is your ultimate, no-fluff guide to everything you need to know before getting hair extensions.

How Many Hair Extensions Do I Need?

The number of extensions you need depends on your natural hair’s thickness, your desired length, and how much volume you want to add. Here’s a breakdown to help you estimate what’s right for you.

By Hair Thickness:

• Thin/Fine Hair:

  • Length: 100–125g

  • Volume only: 50–100g

• Medium Thickness Hair:

  • Length/Volume: 150g+

• Thick Hair:

  • Length/Volume: 200g+

By Desired Look:

• Just Length:

  • Short Hair: 100–120g

  • Medium Length Hair: 150g

  • Long Hair: 200g+

• Just Volume:

  • Half Head: 50–100g

  • Full Head: 100–150g

Pro Tip: For a natural blend, the thicker or shorter your hair, the more grams you'll need.

Understanding Hair Density vs. Thickness

Most people confuse hair thickness with density—but they’re not the same.

• Hair Thickness = Diameter of individual strands.

• Hair Density = How much hair you have on your scalp.

For example, someone with thick strands but not much hair has low density but thick hair. Both factors influence how many extensions you need.

A Quick Hair Density Test:

• Dries in 1–2 mins / Thin ponytail: Thin density

• Dries in 3–4 mins / Medium ponytail: Average density

• Dries in 5–6 mins / Full ponytail: Thick density

• Dries in 8–10 mins / Heavy ponytail: Very thick density

How Hair Length Affects Extension Needs

The shorter your natural hair, the more extensions you’ll need to blend seamlessly.

Hair Length	Thin Hair	Medium Hair	Thick Hair
Very short	125–200g	150–200g	200g+
Shoulder length (12")	75–100g	100–150g	150–200g
Past shoulders (16")	100–125g	125–175g	175–200g

If your haircut is blunt (e.g., a bob), more extensions are needed to create a smooth, natural-looking blend.
