Eyebrow waxing is by far the best option. When using the threading method, the thread actually goes through their teeth. That means that the bacteria or illnesses that the technician may have are going on your face! (Not to mention what they had for lunch. Eww.) DO NOT shave them either. Shaving will make the hair grow back darker and thicker and can actually ruin the natural shape of your eyebrows. Waxing is clean and also the better option because when you get a wax, the hair strand all the way down to the bulb or root is getting pulled completely out, therefore the hair grows back thinner or sometimes not at all!! This way you can get them done less often and save money.
