No, even if it is washed directly with beer.
The reason is very simple. There is really no dandruff-removing ingredient in beer.
Beer is a drink made of barley malt, yeast, water and other raw materials. Its main components are water, ethanol, sugar, proteolytic products and a small amount of water-soluble vitamins.
General dandruff removal products can reduce dandruff in two ways: one is to kill Malassezia parasitized on the scalp, and the other is to inhibit sebum secretion of the scalp.
However, we have counted and found that the ingredients in beer have these functions.
Some people may say that alcohol can kill bacteria, but the alcohol in beer is generally only about 2%, which cannot kill bacteria at all. You can’t wash your hair with a high amount of liquor, can you?
In addition, although sugar, proteolytic products and water-soluble vitamins in beer have nutrition, they cannot be absorbed by human body through epidermis, and may also provide nutrition for Malassezia, which causes dandruff.
Therefore, if a person only uses beer to wash his hair and remove dandruff, it is unlikely that [snowflakes] will have the opportunity to see him every day.
