From what i understand you can't change the hz an appliance gives off and I know if you plug a 60hz appliance into a 50hz socket that it could potentially cause a burnout on the appliance, but what happens if it's the other way around? Providing you have the right adaptor, and the right transformer for the right voltage.
Am i right to assume it would be the opposite and instead of possibly causing a burnout the product will be less efficient?

Depends entirely on the type of appliance, and also the change in voltage (240/220/110V). Read the instructions!
Heaters, toasters and kettles are one thing (it depends on the power rating (=>voltage), and not the frequency.)
Electronics are much more sensitive; it depends on the transformer and power supply.
TVs, CD players, audio generally won't work, and may be damaged.
Some laptops have universal-voltage transformers, which can handle everything. Most don't.
But finally: Read the instructions.

Normally 50 Hz appliances are designed for 220 - 240 V and 60 Hz for 110V. So, if you plug a 60 Hz appliances, it will burn out because of the higher voltage and thus higher current passing through the appliance, not the frequency.
If as you mentioned, the voltage is same, the appliance will work, may be with a reduced efficiency if it is motor driven. If it is a resistive load, should not be affected. But having the same voltage is unlikely, unless as you mentioned, you step up the voltage.

If the voltage magnitudes are the same, power supplies in small electronics won't care about the frequency, since they rectify it to DC anyway.
Any ferrous-core inductors (including transformers) will be operated at slightly lower (83% of nominal) Volts/Hz in the magnetics, which will tend to yield lower losses.
Transformers will produce a 20% higher voltage than would happen at 50 Hz.
Motors will run 20% faster, and efficiency may drop a bit due to voltages not being exactly on-spec.
Resistive devices, such as toasters and heaters, don't care about frequency, so if the voltages are the same, the performance will be identical.

I think if you plug a 50Hz appliance into a 60Hz socket it will run faster or hotter. Depending on the appliance, this could cause it to burn-out.
If you plug a 60Hz appliance into a 50Hz socket, it will run slower.

Not completely sure, but yes I beleive that the appliance will run too fast or hot and will likely go up in smoke.

Not absolutely right. It will not burn out your appliance right away but will eventually cause it to malfunction.
the reason is angular frequency is directly proportional to frequency you get in a house hold electrical supply which eventually changes amount of current resistor & capacitors get by a little.
Following link will explain it clearly if you are an EE student.

It takes more current even it is computer or electronic devices ( Smps Load) if Inductive load eg: motor transformer gets heated !

Agree with swamy.
The appliance will burn out as the voltage level increases that will affect the insulation as a result of which the appliance will burn out.
