Are you looking for an amazingly versatile hairstyle? Do you want something that is undetectable? If so, an interlock weave is perfect for you! Also known as tree braids, an interlock weave is a great strand-by-strand hair weaving method that uses cornrows as the foundation of the style.

The reason why interlock weaves are so popular is that they offer all the benefits of braiding with the look of hair that flows freely. Sound hard? Interlock weaves can be challenging at first. But, with the proper practice, you can create an interlock weave that is beautiful and virtually undetectable.

Before you begin your interlock weave, start with hair that has been properly washed and conditioned. Your first part will be around the perimeter of the head and should be about 1'' to 1 1/4'' thick. Don't worry too much if your part isn't even all the way around; this hair will just be used to blend with the finished interlock weave. Go ahead and cornrow this perimeter to get it out of the way.

Now you're ready to start your interlock weave! Start by sectioning off a small piece of hair that is parallel to your cornrow. Start on one side of the part and make a small section that you will start your cornrow off with. Begin cornrowing the client's hair in that same circular direction. Pinch off a small piece of extension hair from the pack and add this piece to the two outside strands of your braid.

Here's what you do next:

1. When you add the extension hair to the outside two strands, cornrow once.

2. Once you have cornrowed down once, remove a small section of the extension hair from the braid. Move it to the side or hold it out of the way with a butterfly clip.

3. Cornrow once more and then add the extension hair to the two outside strands.

4. Cornrow once and pull the extension hair out to the side braid.

5. Cornrow again and add your extension hair to the two outer strands.

Follow this pattern around the entire head. When you reach the top, you should have one long cornrow that covers the entire head and has extension hair flowing freely from the cornrow. Add extra extension hair to your cornrows when you reach the top of the head for a fuller look.

When you're on the last braid at the top, braid it out to the very end and stick this braid into your existing cornrows, making the top as flat as possible. Sew the cornrows in place to secure.

Don't forget to remove the first set of cornrows you made with the hair around the perimeter. When you remove the cornrows, use your fingers to work the client's hair in with the weave and blend until you are satisfied with the results.
