Density Guide

HOW MANY BUNDLES YOU ACTUALLY NEED FOR THE RESULT YOU WANT

It’s Not Just About Length.

Every install is different. Density, natural hair, and the desired result all change the strand thickness and number of bundles you’ll need.

To choose the right combination, you need to consider:

Your client’s natural density

Finer hair requires fewer bundles while thicker hair needs more to blend.

The strand type you’re using

Regular vs. thick strands will impact how much hair you need to achieve the same result.

The haircut and baseline shape

Blunt cuts usually need more bundles, while layered or tapered ends require less.

Our Strand Guide

Choose the right density based on your client’s hair and desired result

Regular Strands

Regular strands are ideal for ALL hair densities
and are the safest option for delicate or thinner hair.

When to use:

Fine hair

Layering

Natural movement

Thick Strands

Thick strands are designed for clients with thick hair or when a fuller, more voluminous finish is desired.

When to use:

Dense hair

Building fullness

Dramatic volume

You can also mix densities to customize your blend—visit our Pro Access page to learn how to use
both together effectively.

Our Bundle Guide

Below are our general guidelines to help you determine how much hair is needed for a balanced, natural-looking install based on your client’s density and desired result.

Volume Only Add Length Add Significant Length (26")
Thin Hair 1–2 bundles 3–4 bundles 5–6 bundles
Normal Hair 2–3 bundles 5–6 bundles 6–7 bundles
Thick Hair 3–4 bundles 6–7 bundles 8–9 bundles

*Thin, normal, and thick in this guide refer to the client’s overall hair density, not the thickness of individual strands. A client may have fine strands but a lot of hair, which would still be considered normal or thick density.

How Your Haircut Affects Bundle Count

To choose the right amount of bundles for your client, it’s important to take haircut shape into consideration. Once you’ve identified your client’s density range from above, use the guidelines below to choose the right bundle amount based on their haircut.

Tapered wispy haircut

Tapered/Wispy Haircuts

You can usually choose the lower end of the bundle range. For example, if the guide suggests 5-6 bundles, choose 5.

Blunt one-length haircut

Blunt/One-Length Haircuts

Choose the higher end of the bundle range to create a seamless blend. For example, if the guide suggests 5-6 bundles, choose 6.

Strand Weight & Options

Our nano extensions are available in different strand weights depending on length and density. Choosing the right strand size helps you control both the fullness and the number of bundles needed for each install.
