In fact, some people might experience irritation or allergic reactions from applying Vicks to the scalp.
In short, don't rely on Vicks VapoRub for hair growth. There's no scientific basis for it, and it could potentially cause irritation.
If you're concerned about hair loss or want to promote hair growth, it's best to consult with a dermatologist or other healthcare professional. They can help you determine the cause of your hair loss and recommend evidence-based treatments.
