Sad to say a waste of money

My experience with staff was amazing, but unfortunately my experience with the tech not so much. I had 12 sessions for underarm and Hollywood, but super sad to say that my 2nd week after finishing my sessions I could already see that noooothing has changed. Very sad that I spent all that money there and back to square one. Hair is growing as if never lasered, the shadow has returned, and ingrown hairs after shaving are a nuisance. Unfortunate to say I wasted my money and time. I’m hoping for others who go that the tech improves some day!
