Fermented beer contains serious yeast provisions that give an unbelievable volume to tired tresses.
How to prepare a volume mask
You need half a cup of beer that was previously left for several hours in an open container. Pour over a tablespoon of sunflower oil or canola and a raw egg. Apply the mask over the wet hair, leave it for 15 minutes then rinse with cold water.
Another option is to sprinkle with beer all over your hair. You can put in an empty spray container a glass of beer. These treatments can be applied every two weeks.
