Yes, boys can absolutely dye their hair! The notion that hair dye is exclusively for women is outdated.
The trend of men dyeing their hair is becoming increasingly popular, and it's a great way for anyone to express their individuality and change up their look. There are no restrictions based on gender when it comes to personal style choices like hair color.
Whether a boy wants to try a subtle color enhancement, a bold statement color, or simply cover up gray hairs, dyeing hair is a perfectly acceptable form of self-expression. Go for it!
