The 6D hair extension has gained popularity since it offers the following advantages.

Easy Application and Removal

A 6D hair extension application takes 20 minutes compared to 2-3 hours for I-tip extensions.

Additionally, they are easy to remove. You just need to pop the microbeads and slide the hair off. You have to be careful when removing, however. Otherwise, you might end up tearing some hair strands.

Invisible Bonds

The joint diameter is 1.7 mm making the borderline seamless and invisible within the hair. Because of this, your hair will feel and appear natural.

Last Long

6D hair extensions can last anywhere from 4-12 months. The period depends on the hair extension quality, hair care routine, and how fast the hair grows.

The Cons of 6D Hair Extensions

These extensions may be great, yet they come with some flaws. Here are the disadvantages.

Relatively Expensive

The 6D Hair Extensions machine price is high. But its durability makes it worth the expense. Moreover, salons charge a higher amount for this method than other extensions.

Slow Process

The 6D extensions machine requires you to grab a small amount of hair at a time to protect the hair from damage. This can be time-consuming and frustrating.

Note: Keep the machine away from the scalp to protect your hair from ripping off. 

How To Apply 6D Hair Extensions (Step-By-Step)

This process requires a 6D hair extensions machine, parting comb, and pre-bond hair.

Step 1: Section The Hair

Part the hair into six or more sections, depending on the volume. And then secure the parts to make it manageable. 

Step 2: Prepare Pre-bond Hair

Flip the pre-bond hair, ensuring the bond is open as the hair drops downwards. The open buckle side should be facing you and not the closed side. Ensure that the bonds are loose.

Step 3: Set Install Machine

Take the 6D machine, toggle the metal button then apply the plastic buckle. Push the clasp in and adjust it to make sure it fits well.

Move your hand closer to the end of the machine gun to make it easy to close. Then, remove the plastic buckle by pulling from either side till it comes out. 

Note: The hair extensions should remain on the machine at this point.

Step 4: Position the Plastic Buckle

Turn the buckle upside down, then put it on the top side of the machine. 

Set it at the center and gently press the machine’s handle to see if the buckle and pre-bond hair coincides. Make sure you place it well.

Step 5: Apply Hair

Take a small amount of hair from each section, about 2 inches thick. The bonds will not stick to the hair if the hair is too thick.

Hold the end of the machine, then move the small section of natural hair between the gun using your other hand. Spread the hair evenly as you hold them down with the silver bonding and clamps.

Bring the machine as close to the roots as possible, then press and hold it for a moment.

Note: The dividing line should be as straight as possible.

Step 6: Remove the Buckle

The clamps break the plastic when you unhook the machine. You will notice that the plastic buckle remains stuck to the hair. 

Break the metal off the buckle by bending them slightly. 

How to Remove 6D Hair Extensions

The 6D hair extension machine comes with middle-sized pliers for removing the bonds.

Here is a simple procedure to follow.

Step 1: Section the Hair.

Use your fingertips to part the hair into six or more sections, then secure them with hair clips. Do not use a comb as you will break off hair roots.

Step 2: Locate Buckle.

Locate the C-shape buckle for each section. The opening of the buckle should face upwards. If not, use your index finger and thumb to pinch the end of the buckle to fix the position during removal.

Step 3: Remove the Buckle

Use the pliers and ensure the zigzag part is facing downwards. Put the C-shape buckle into the zigzag shape and press gently. 

The bonds will break and allow you to slide the extensions from the natural hair.

FAQs About 6D Hair Extension

What’s the Difference Between 6D-1 and 6D-2 Extensions?

First-generation 6D hair extensions have ten sets of hairpieces. This way, you can only apply a few hairs, which can easily fall off. Also, the application machine is heavier and needs much strength to press and release.

While second-generation 6D hair extensions have five sets of hairpieces. The C-shape buckle has five hooks, making the gaps larger and the amount of hair introduced is twice that in 6D-1. 

A 6D-2 machine is convenient, and the application is more secure. But, the hair extensions are bigger and more visible than 6D-1 hair extensions.
