A well-known
dermatologist in Delhi claims that it is not possible to get the advertised images in a single session owing to the fact that hairs grow in cycles. There is a resting phase when the hairs cannot be detected by the pulses of the laser as well as the falling-out phase. It is during the growth phase of the hair when it responds the most to laser hair removal treatment which is why there is a need for multiple sessions spanning over months.
