Someone asked the other day about having laser hair removal on blonde hair. It simply will not work, I said, because laser needs some colour in the follicle in order to absorb the laser energy.
If you can imagine pointing a laser, used for hair removal, at a white wall or a piece of white paper – switch the laser on – nothing will happen because the laser beam will pass through it without affecting it. That’s what happens when the hair is white, or red for that matter, nothing happens!
If instead you used black paper or a brown or blue wall, or any colour other than red, you would leave a hole in it. That is because the laser beam will permanently destroy anything with colour in it.
It’s for this reason that we remove any surface hair so that the laser beam will only affect the follicle and destroy it. White, grey or red hair needs Electrolysis.
