Red lights on the hair follicles

Yesterday I caught up with one of my mates who uses an Eliza light hat for his Parkinson’s. He told me, with some quiet delight, that his grey hair had been slowly resuming its previous brown colour.

It reminded me of another mate, also using an Eliza for Parkinson’s whose previous bald head is now populated with a triumphant fuzz of hair.

Most Australians would have seen the advertisements starring Shane Warne promoting lasers as the way to rejuvenate hair. Ignore the adverts.

It seems that the hair-growing effect is nothing to do with the laser, and everything to do with the wavelength used in the laser. And of course, you can get the same wavelengths in LEDs. The Very Visible Red wavelengths (630-670nm) are the way to go.

If you have already made your Eliza with nice red LEDs, then daily use might just get that hair regrowing…
