make the garlic oil, smash and peel cloves of garlic. Transfer to a medium pot, add olive oil, and heat over medium-low until bubbles form around garlic, 3 minutes. Let cook 10 minutes, reducing heat to low if garlic begins to brown. Remove from heat and let cool to room temperature, 45 minutes. Once you’re done, you can use it in your hair and watch how the garlic oil benefits it in no time!
