Hello, Thank you for your question here at HealthCareMagic. I ve read your inquiry and understand your concerns. You want to know if you can start a laser hair removal treatment on the zone you also have a pilonidal cyst. The answer to your question it s not that straightforward as you may hoped. It depends on the severity of the pilonidal cyst, if it leaks puss, the zone of redness, whether or not pain is present. In short terms any kind of infection represent a contraindication for laser treatments. On the other hand if your condition is mild and none of the manifestations listed above are present, you can start the sessions for laser hair removal provided that the pilonidal cyst is also under treatment and healing. Please note that laser hair removal also has some adverse effects you should be aware of that include intense itching, change of color - pink skin (mild burns), redness, and swelling around the treatment area or follicular edema. Wish you fast recovery! Do not hesitate to ask if you have further questions. Best Regards,
