Best time to start laser hair removal

Is there a specific time of year that's better for starting laser hair removal? I've heard summer isn't ideal but I want to understand why and whether it's a hard rule or just a preference.

The advice to avoid starting in summer is practical rather than a strict rule, and it comes down to sun exposure. The biggest risk factor for laser hair removal complications is treating skin that's tanned, sunburned or actively getting a lot of UV exposure. Sun exposure before a session can increase melanin in the surface layers of skin, which raises the risk of burns or pigmentation changes from the laser. Sun exposure after a session to healing skin also increases hyperpigmentation risk. In summer most people are naturally getting more sun on exposed areas, wearing less coverage and are more likely to have some level of tan. Fall and winter are often recommended simply because skin is more reliably unexposed during that time and aftercare — which includes strict sun protection — is easier to maintain when you're not outdoors as much.

I started my sessions in October and I think that timing worked really well. By spring I had completed most of my course and the treated areas were well into the healing phase. I'd read general guidance on timing and treatment protocols at https://bellasanamedspa.com/service/laser-hair-removal before starting and it helped me think through the logistics. That said, if you're disciplined about sunscreen — SPF 50 every day on treated areas, no tanning beds, covering up when outdoors — summer sessions are possible. It's more about your lifestyle habits during treatment than a seasonal absolute rule. Just be honest with your provider about your sun exposure habits and they can advise accordingly.
