Mandy IPL works best on darker hair colors. People with lighter hair colors such as red, gray and very blond (white) hair, we advise not using IPL as a hair removal method. This is because very light hair does not contain enough melanin to carry light down to the root, while red hair contains another type of melanin that does not respond as well to IPL treatments.
It is possible to see results with blond hair, but more treatments may be needed than for people with darker hair before results can be achieved.
