Of course, using sunblock is always a good idea, but if you have laser hair treatment done during the winter, spring, or autumn, it will be easier to protect the treated areas from the sun. If you have an easy time remembering to put on daily sunblock, getting this hair treatment done any time of year shouldn’t be a problem for you. If you want less hassle, having it done during a season when you’re more out of the sun may be a good choice for you.
