Does laser hair removal work on blonde or grey hair?
No. Laser and IPL hair removal target melanin in the hair shaft, so blonde, red, grey and white hair cannot be treated reliably at any wavelength. Electrolysis remains the only proven option for hair without melanin. Manage this expectation at consultation, not at session four.

Why wavelength cannot fix it
Every light-based hair removal system relies on selective photothermolysis: melanin in the hair shaft absorbs light, converts it to heat, and destroys the follicle. Hair with little or no melanin does not absorb enough energy to reach that temperature. Changing wavelength changes how much melanin absorbs — it cannot create a chromophore that is not there.
What to offer instead
Electrolysis is the only method with evidence for non-pigmented hair. Some clinics offer it alongside laser precisely so this consultation ends in a booking rather than a refusal.
For clients with mixed hair — dark and blonde in the same area — treat the pigmented hair with laser and be explicit that the light hair will remain. Photograph before treatment so the outcome is documentable.
