X-rays for hair removal are currently banned by FDA in the US. In the first half of the 20th century, X-rays were used around the country in salons for hair removal. The results, while sometimes permanent, caused cancer, disfigurement and death in clients. While they are sometimes used in extremely limited amounts for medical eyelash removal procedures, X-rays are no longer allowed for cosmetic hair removal.
