No, applying methylated spirits (also known as denatured alcohol) will not make your beard grow faster. Methylated spirits are primarily used as a solvent, fuel, or cleaning agent and have no known properties that can stimulate hair growth.
Beard growth is largely determined by genetics and hormonal factors, such as the levels of testosterone and dihydrotestosterone (DHT) in the body. While there are certain products that can promote healthy hair growth, such as biotin and minoxidil, methylated spirits is not one of them.
In fact, applying methylated spirits directly on the skin can cause irritation, dryness, and even damage to the skin and hair follicles, which can actually hinder the growth of facial hair. It is important to only use products that are specifically formulated for promoting hair growth and to consult with a healthcare professional if you have any concerns about your beard growth.
