Facial hair can be removed using various methods, including temporary solutions like shaving, waxing, tweezing, and depilatory creams, or more long-term options such as laser hair removal, electrolysis, and prescription creams. Shaving is fast but results are temporary (1-3 days), while root removal methods like waxing or epilating last longer (2-6 weeks). Professional procedures like laser hair removal and electrolysis can offer permanent hair reduction.
