Best Deep Conditioner for Hair Extensions – Buying Guide

Here’s what you need to know before getting a deep conditioner.

Natural Ingredients or Artificial?

It’s a great thing if the deep conditioner is made with natural ingredients. This is especially great for human hair extensions because it’s just like how you would treat your natural hair. When the ingredients consist of natural products, your extensions last longer and retain that natural look.

However, if your extensions are synthetic, you don’t really have to worry about natural ingredients or not. This is because synthetic hair is made from artificial fibers, and there isn’t much need to be particular about natural ingredients.


A deep conditioner is easier to wash out, or even leave-in, when it’s lightweight and not heavy on the strands of your extension. Although this may or may not be written on the product pack, you can easily check this out in reviews if you’re making an order online.

Instant Conditioning

Check if the conditioner works instantly, or you’ll have to wait for a couple of hours or days before it penetrates your extensions deeply. However, this largely depends on you and the patience you can exert while applying your conditioner.
