Let me first remind you of the structure of hair, just in case you need it!
1. Temporary repair of hair
2. Smoothing down of the cuticle
3. Reduction of frizz/flyaway hair for the curlies among us.
4. Softness of hair post conditioning
This is why I would like you to learn this word - adsorption. Here is one of my nifty diagrams to show you how adsorption works.

This is not to say that penetration of hair conditioner does not happen. Over the course of the last three years I have read numerous studies into different penetrating abilities of conditioning substances. This will be the subject of the next post. However to whet your appetite, I would like to present to you the three main ways that penetration is described in scientific literature. These methods generally apply to undamaged hair because damaged hair will pretty much let in almost anything.

The list of substances that CAN penetrate hair (i.e shown in scientific studies) will be here on Wednesday, so don't miss that! After that will be studies on whether heat and extra time make a difference to conditioning hair.
