The best known benefit of waxing is that the hair doesn't grow back very quickly. Waxing removes the hairs from the root. With shaving, the hairs are cut off close to skin level. Even with a very close shave, this still leaves a considerable amount of the hair just below the surface ready to appear in a day or two.
I have red hair, can I use an IPL device?
IPL is not suitable for everyone. It is most effective on light to medium skin tones with hair ranging from natural blonde to dark brown or black. The device is not effective on very blonde, red, grey or white hair where the smaller amount of melanin would not absorb the light energy.
