How to Choose Hair Thickening Shampoo for Men 

Your choice should take into account the following:

Go for Ingredients that Add Volume 

The formula you choose should contain proteins that bond to the hair to add volume, strand by strand.

If you have fine hair that you want to make thicker, then look for silicone derivatives to build volume.

Wash your hair regularly, as the static electricity from clean hair naturally boosts volume and thickness. 

Look for Deep Cleaning Shampoos 

An effective formula removes all traces of excess sebum and dirt from the hair without stripping natural oils.

A clean scalp will allow for better nutrient and moisture absorption, boost growth and add volume to the hair.

This hair thickening formula is designed to infuse nutrients into each hair strand on your head, while keratin and collagen create thicker, fuller, and more beautiful tresses with each wash.

They also help alleviate several scalp-related issues like dandruff, excess sebum, and dead skin cells.
