A Brazilian is one of the most expensive areas to keep up by waxing, which is exactly why it is the clearest case where laser wins over a decade. The question is not whether laser is cheaper - it usually is - but how soon it pays for itself.
Waxing a Brazilian for 10 years
At about $59 a visit every 4 weeks, that is roughly 12 visits a year, or ~120 visits over a decade - more than $7,000, and that is before any price increases or tips. The bill never stops; it just keeps compounding month after month.
A laser course over the same 10 years
A typical course of 6-8 sessions at $200-$400 each completes in year one, then needs only about one maintenance visit a year. Over a decade that lands well under the waxing total, with most of the cost paid up front instead of dripping out forever.
When it breaks even
For a Brazilian the crossover commonly falls around 18-24 months. Every year past that point, waxing keeps charging you while laser largely stops - so the longer you would have kept waxing, the bigger the gap. Run your own prices in the calculator to see your exact crossover.
