Cksinghani Jee, essentially, you're asking which is better -- a bujjar kurehit or a kurehit. I could ask you the same question in different words: which is better -- having your head cut off slowly or having it removed swiftly in one blow? While one way may feel "better" than the other in the immediate present, both choices will lead to the same outcome, right? A Sikh wouldn't choose between screwing up a LITTLE or screwing up a LOT, because either way, any screw up is costly.
Removing your kes through waxing, shaving, plucking, trimming etc, is a bujjar kurehit and one who commits such an act is no longer a Sikh. Bleaching your kes, like dying it, is a kurehit and while it is a "sin" to a lesser degree than removing the kes, does that make it "better"? Not really. I know it's difficult and the pressure to conform can be almost unbearable, but know that you'll never find happiness by turning your back on your Guru.
If excessive hair growth is caused by some type of hormonal imbalance, there's nothing wrong with seeing a doctor. In most cases though, hair that is already on your face will not go away. Treatment can prevent future hair growth, but in most cases, kes that you already have will remain intact. Often, women have facial hair for no apparent reason, ie. it isn't linked to hormonal issues at all. If that is the case and it isn't caused by a hormone imbalance, then try to balance out your priorities instead -- Sikhi above the world. With that choice, you'll never go wrong.
