A: In some cases the effect is permanent, although this is not true for everybody. It is always possible for new hair to grow after any form of hair removal treatment. However, laser hair removal is the nearest we can get to achieving long-term excellent results. Occasionally it is possible to see the re-growth of small amounts of hair over a period of time but this is usually weaker and lighter in colour and can be treated again if necessary. Some clients require 'top-ups' a couple of times a year.
