Keratin extensionsare individual hair strands that come with a keratin adhesive at the tip of each strand. Unlike clip-in or tape-in wefts, you don’t use tape or clips to install keratin extensions. Instead, a heat tool is used to melt the adhesive at the base of each strand and fuse them in place. 

This post will walk you through the steps to install keratin extensions. Plus, we’ll provide some quick tips on how to maintain your keratin hair extensions. 

How to Install Keratin Extensions

1. Buy Good Quality Keratin Extensions

Buy high-quality human hair keratin extensions from a trusted brand like Zala. Human hair extensions look entirely natural and blend perfectly with your natural hair. 

Zala’s keratin hair extensions are made from the finest quality hair, and you can style and treat them just like your own hair.

Also, make sure to buy the hot fusion bond tool to melt the glue at the tips of the extensions, so they can bond to your hair.

2. Wash Your Hair

The second step is to wash your hair with a clarifying shampoo to remove product buildup and oil. This is important for the extensions to fuse to your hair. Product buildup and oils can weaken the bond. After washing your hair, let it air-dry completely. 

3. Clip Your Hair Up

Next up, clip your hair on the top of your head while letting loose a thin, horizontal row at the nape of your neck (ear-to-ear level). 

4. Lift a Small Portion of Hair on One Side of Your Head

Turn on the hot fusion tool so it can heat up. Take a section of hair from the hair left loose at the nape on one side of your head (the same width as a single keratin extension) and about 1 inch from the edge. 

5. Place the Extension Alongside Your Hair

Now take the extension and place it alongside the hair section you created in step 3 (about 1 inch from your scalp). Make sure the glue at the tip faces your scalp. 

6. Attach the Extension

Next, clamp the keratin extension with the hair section for five seconds using the fusion tool. This will melt the glue at the tip of the extension and attach it to your hair. 

7. Compress the Molten Glue With Your Thumb

After removing the heat tool, pinch the molten glue with your thumb and squeeze it together with your natural hair for 3-5 seconds. 

8. Repeat the Process to Install the Extension in the First Row

Repeat the steps above to apply all of the extensions until you reach the end of the first horizontal row. The distance between each extension depends on the density and volume you want to achieve. Putting them closer together will make your hair look fuller.

9. Create More Horizontal Rows and Install More Extensions

After installing the extensions in the first row, you can create a second row, about 1 inch above the first row. Next, install the extensions in the second row using the same technique as the first row. 

Repeat the same process to install all of the extensions in multiple horizontal rows until you reach the temple of your head. Next, unclip your natural hair at the top of your head, shake your hand, and run your fingers through the locks. This will let your natural hair blend with the extensions. 

Allow the keratin bond to strengthen for 30 minutes before brushing and styling your hair. 

Congratulations! You’ve learned how to install keratin hair extensions. 

Tips to Maintain Your Keratin Extensions

Here’re some quick tips on how to care for and maintain your keratin extensions:

  • Shampoo your hair 3-4 times every week. Use products free of harsh chemicals like sulfates, alcohol, and parabens.
  • After washing your hair, ensure it is fully dry. You can either allow your hair to air-dry or use a blow dryer at a low temperature. Treating your hair with heat tools at a high temperature can weaken the bond between the extensions and your hair.
  • Style your hair however you want. But make sure to use lightweight products and brush your hair gently.
  • Use a brush designed specifically for extensions to prevent possible damage. Or you may use a wide-toothed comb to brush your hair together with the extensions.
  • Make sure to brush or comb from the ends towards the base of your hair to avoid possible damage.
  • Don’t wear your keratin extensions for more than 6 months as they can apply excess weight and stress on your natural hair, which can cause hair damage.
