Laser hair removal is considered a semi-permanent hair reduction method. This means that while it significantly reduces hair growth, it does not guarantee permanent removal of all hair in the treated area. The majority of people who undergo laser hair removal can expect an approximate 80% reduction in hair growth. However, factors such as hair color, skin color, hair texture, and hormone levels can affect the results. Some hair may grow back, but it is typically finer and lighter in color. Additionally, maintenance treatments may be required over time to maintain the desired level of hair reduction.
