I guess the desi logic would be that baby being out and about without adequate sun protection would become darker as a result of having oil applied to its body lol... can you imagine their shock to find that their gora chita grandson now has a tan!!
Chocolate makes you breakout
If a woman eats coconut when she's preganant her child turns out to be fair. I haven't seen anyone follow this yet so I can't really comment on the validity lol
The oil making you darker thing could be true - I've heard that many girls here in the UK use baby oil and other such oils on their bodies before going out to sunbathe and this works by making them tan faster...
1) Don't pull out a white hair as two will grow back in it's place.
What a load of cobblers!
2) You don't need to use sunscreen if it's cloudy outside.
Harmful UV rays can penetrate through glass (which is why you can get a tan in the car) so of course they'll penetrate through clouds.
3) You can reduce your pore size.
Not true, pore size is gentically predetermined, the only thing you can do is make sure they're clear and clean.
