Does using beard oil help with hair growth in men's facial hair (beard, sideburns, etc.)?

Using beard oil can help with beard hair growth to some extent by promoting healthy hair growth and reducing hair damage. The oils in beard oil can help moisturize the skin under the beard, which can reduce itching and flaking, promoting a healthy environment for beard hair to grow. However, the primary factor affecting beard growth is genetics and hormonal changes, so using beard oil alone may not significantly increase beard growth. If you're experiencing slow beard growth, it's best to consult a dermatologist or trichologist for personalized advice.
