#4. Henna King Manly Guy ($13 @ Amazon.com)
Who doesn’t want to be a manly guy? Plus, all-natural henna-based hair coloring options are the best hair dyes for men who hate feeling like a Toxic Avenger after they’re done dying. That’s because henna-based dyes lack chemicals that can sometimes cause irritation and allergic reactions.
PROS: Cruelty-free, no harsh chemicals, a wide range of colors, good for facial hair
CONS: May be somewhat inconsistent in the evenness of the application, need to be reapplied often.
