Alcohol consumption can indirectly cause hair loss by affecting overall health and leading to certain health issues that can cause hair loss. Heavy alcohol consumption can lead to nutritional deficiencies, which can deprive the body of vital nutrients, including those necessary for hair growth. Alcohol can also lead to elevated stress levels, which can stunt hair growth. In addition, alcohol can lower both testosterone and estrogen levels, which can affect overall growth and development, including hair growth.
When it comes to hair products, its best to stay away from those that contain alcohol, as heavily-concentrated alcohol hair products can damage hair. Short-chain alcohols, such as ethanol, methanol, and propanol, are considered "bad" alcohols, as they are known for their drying properties and can excessively dry the scalp and hair, leaving the hair cuticle rough and brittle, causing frizz, and making the scalp itchy, flaky, and prone to irritation.
However, not all alcohols are created equal. Some alcohols can be beneficial and even hydrating for the hair, such as long-chain alcohols.
In summary, while alcohol consumption does not directly cause hair loss, it can indirectly contribute to it by affecting overall health and leading to certain health issues that can cause hair loss. Its best to avoid hair products that contain alcohol, especially short-chain alcohols, which can excessively dry the scalp and hair.
