Flat bond hair extensions in the hair

Hair Extensions Bonds – Good vs Bad…

May 10, 2013

We all know hair extensions can look good or bad at first glance, however, the real proof is in the Bonds!

How the bonds are applied is fundamentally important for the following reasons:

  1. To avoid damage to your natural hair
  2. For your comfort
  3. For discretion – general appearance and visibility

Over the years I have seen some poorly applied bonds, hence my blog on this! I’m talking about keratin bonds as that’s what Bond Hair specialises in. Keratin is a natural, protein-based substance found in our hair, so it’s not likely to cause any allergic reactions. I favour keratin bonds as the technology is safe and the bonds secure the extensions in place for many months.

What good bonds should look like

Good hair bonds should be:

  • small
  • flat (or cylinder depending on your view and type of extension applied)
  • comfortable
  • applied a couple of centimetres from the root


What bad bonds can look like

Poor application of pre bonded hair extensions tend to be:

  • large and bulky
  • rolled into a sausage shape 
  • uncomfortable / pull on the natural hair
  • applied too close to the root


The correct way to apply keratin bonded extensions


  • Take even small square sections of hair (roughly the same thickness as the strand in which you’re applying) DO NOT put in a triangle shape as this is pulling the hair away from its natural growth pattern.
  • Slide the extension bond a few centimetres down the clients natural hair, DO NOT apply right up at the root, this is far to close, feels sore and tight for the client and could snap the hair at the root. Technicians who are applying right at the root are doing it wrong. Extensions should not be sore, after 1-2 days you shouldn’t feel them at all.
  • Bonds should be applied in neat rows and bricked up across the head from one side to the other. They should not be applied on the nape of the neck of right into the front of the hair line as they will be visible- and people hair tends to be naturally finer in these places so it’s best to avoid applications here.

Rolled vs flat bonds

Here at Bond, we apply flat bonds, these are best as they allow you to fold the bond neatly around the hair, rather than fusing and rolling the keratin into the hair forming a cyclinder shaped bond. Rolled bonds, if done badly, can be long, large and heavy not to mention visible. Many hair extension technicians do a good job and achieve small rice grain sized bonds, ideal for fine hair and applying ‘micro bonds’ but for most, we recommend our small square bonds.

Try Before You Buy

Unsure about bonds? We offer a FREE Try before you buy service. At consultation we can apply a couple of bonds to your hair so you can see how they feel, before committing to hair extensions.

Bond application – Bad vs Good

Side by side you can see an example of bad bonds and good bond. Notice the direction the hair is pulled…the rolled bonds are bulky and, although grown out in this photo, were clearly applied to close to the root initially, which has caused breakage of the natural hair.

The good bonds are applied neatly, taking square sections and have been applied a few centimetres down from the root.
