🔬 What Are Knots on Lace Wigs and How Does Bleaching Work?

If you’ve ever taken a close look at a lace front wig, you’ve probably noticed tiny dark dots at the hair roots — these are called knots. Understanding how these knots are formed and how bleaching works is key to making your wig look as natural as possible.

In this post, we’ll dive into:

• What are knots on a lace wig?

• How are wig knots formed?

• What is knot bleaching?

• Should you bleach the knots on your wig?

Let’s break it all down!

🧷 What Are Knots on Lace Wigs?

When making a lace wig, each individual hair strand is hand-tied (ventilated) to the lace base. To secure the strand to the lace, the technician ties a small knot, which holds the hair in place. These knots appear as tiny dark dots on the lace, especially if the hair is dark-colored.

🔍 How Are Wig Knots Formed?

Knots are made by looping the hair through the lace holes and tying it securely. Depending on the tying method, there are two main types:

1. Single Knot

   • One hair strand tied once

   • Smaller, less visible, but not as durable

2. Double Knot

   • Two hair strands tied twice

   • More secure and durable, but the knots are more visible

✅ Most lace front wigs and 13x4 lace wigs use a mix of single knots at the front (for realism) and double knots in the back (for durability).

🎨 What Is Knot Bleaching?

Bleaching the knots is a process where a lightening agent (usually hair bleach) is applied to the lace base to lighten the dark knots, making them blend better with the lace and the scalp.

Bleached knots look more natural, as it appears that the hair is growing directly from the scalp — especially on HD lace wigs.

💡 How It Works:

• Hair bleach is applied only to the underside of the lace

• It lifts the dark color of the tied knots

• After a few minutes, the knots turn a light brown/blonde shade

• The result is a more realistic hairline

⚠️ Pros and Cons of Bleached Knots

📌 Pro Tip: If you don’t want to bleach the knots, consider a pre-bleached lace wig or use wig concealer to hide knots without chemical processing.

👩🔬 Should You Bleach Your Wig Knots?

It depends on your preferences:

• If you want a flawless hairline and realistic part, bleaching is worth it.

• If you prioritize wig lifespan or have a light-colored wig, it might be better to skip bleaching and use makeup instead.

Many high-end lace front wigs now come with pre-bleached knots, pre-plucked hairlines, and transparent lace, making your install much easier!
