With the release of at-home gel manicure kits, whitening teeth devices and do-it-yourself keratin treatments, it's getting easier and easier to bring the salon home. And with more autonomy, cheaper long-term costs and, obviously, the ability to stay at home (always a plus), it seems like there's few downsides to taking a turn as the technician.

That is, unless you're looking for results equivalent to what the same process would get you at the salon. As appealing as the DIY lifestyle can be, there are some treatments that are best left to the professionals-not just for the results, but also for your health.
