Drawbacks:
Like anything else, moderation is the key while using beer for hair care. There are some drawbacks of using too much beer shampoo. The alcohol in a beer shampoo can be too drying and hence the hair can become devoid of natural oils, making it flat. This is why beer shampoo is better suited for oily hair than color-treated or dehydrated, dry tresses, as they tend to make oily hair feel drier while still keeping it healthy. It is important to remember that beer is not a complete substitute for regular shampoos and conditioners, but can be used for an occasional clarifying rinse for fine or dull hair.
