Dear Munk,
Shampoo can not possibly stop Pattern Baldness. However, if you are suffering from this condition I suggest you find shampoos that contain less chemicals. There are a lot of very harsh chemicals in regular shampoos like Sodium Laureth Sulfate, DMDM, DEA, TEA and phlatates that can be potential health hazards in the long run. Avoid those.
For hair loss sufferers, look for shampoos that coontain Vitamin B Complex proteins like Panthenol, Biotin, Aloe Vera and Rosemary. If you have oily hair, find those with lemon extract too. In short, try to find an organic shampoo like from Body Shop. It works well together with your other hair loss treatments.

Rogaine will costs you around RM 180 for 1 months supply. You can get it in any major pharmacy. If you can't get it, consider getting Minoxidil 5%. Tell your pharmacist that you want Minox 5% and he will recommend you. Rogaine is also Minox 5% formula, just the brand name is more famous.
As what is the difference between the 2, Rogaine foam disperse foam, making it easier to apply while the normal one is liquid. But since you need to apply it to your scalp and not your hair, I find that the liquid one is more logical to use..furthermore it's a little cheaper.\

Are you diagnosed with a thyroid problem? If you are diagnosed with either hypo or hyperthyroidism, then it may be a cause for your hair loss.. But since you are mentioning about reclining hair line on the top left and back, then it shows symptoms of early stage Pattern Baldness. Together with your age, most cases of severe Pattern Baldness will start at this age. Based on some diagnosis of a few of my friends, your situation might worsen further if you do not treat it. I strongly suggests you see a doctor soon or you can participate in my website's free diagnosis program for free.
I am currently arranging with my friend, a Dermatologist from Singapore to provide help and free diagnosis for hair loss sufferers directly from my website and the page will be up soon. I will keep you updated.
As for now, try getting Vitamin B Supplements to keep your hair thick.
American diet contains a lot of salt and meat..which can stress out your body. That is why most Americans will suffer from hair loss.

No, no there's no baldness on the back..its more like on the side left, i took a picture of my top scalp, and it seems fine. I will consult a doctor soon but where do I start? Just go to a normal clinic?
