How much long-term hair reduction can laser treatment achieve?

What question did the researchers ask?

The review included randomised trials with follow-up spanning a complete hair-growth cycle for the treated site, allowing a more meaningful look at long-term reduction rather than immediate shedding.

What did they actually find?

Reported long-term reduction ranged from about 30% to 74% for Nd:YAG and 35% to 84% for Alexandrite lasers. Leg studies tended to show the greatest reduction and facial studies the least.

What should you keep in mind?

The evidence base was small and results varied by body site, device and follow-up. Hair colour, skin type, hormonal drivers and completion of a full course all affect an individual result; the realistic aim is long-term reduction rather than guaranteed permanent removal.

What does this mean for a Highfield consultation?

Long-term reduction varies with device, skin and hair characteristics, course completion and follow-up. We consider that finding alongside independent guidance, your medical history, examination and priorities. It can support a better-informed decision, but it cannot promise a personal result or decide whether treatment is suitable.
