Tweezing

Pros: The most popular technique, plucking guarantees a clean, shapely arch.
Cons: Since it requires precision, it can take time and be pricey.
Cost: $20 to $80.

Waxing

Pros: This inexpensive and fast method pulls hairs out by the roots.
Cons: With less control than tweezing, mistakes are more common. It's not a good option for people with sensitive skin or those using retinol-based skin creams, because when skin is fragile, it can peel off with the wax.
Cost: $10 to $30.

Threading

Pros: In this ancient technique from the Middle East and Asia, a technician twists threads together and pulls out the hairs caught between them. It's inexpensive, and unlike tweezing, which removes single hairs, it catches several at once.
Cons: Some regard it as unsanitary (one end of the thread is held in the technician's mouth), and skilled threaders are often hard to find.
Cost: $5 to $20.

Electrolysis

Pros: A technician inserts a thin metal probe into each hair follicle. The probe delivers an electric current that, after several sessions, should destroy the root permanently.
Cons: Your brows typically thin as you age, so removing them permanently means you may end up with too few when you get older.
Cost: $30 to $40 for a 15-minute session.
