After acne, the biggest cosmetic problem facing men is baldness. No matter how you try to explain it away, the majority of younger men feel embarrassed as their hair falls out. For those who like statistics, it's estimated that hair loss affects about 30 million men in the US with the majority showing serious loss before the age of 35 years. There are many different causes from those pesky genes, to lifestyle choices, to high stress levels, to chemicals in the environment. No matter what the cause, the burning question is always what to do about it. The most common reaction today is reaching for the pill bottle. The pharmaceutical industry has sold us on the idea there's a pill to cure every problem. And, when it comes to male pattern baldness, this is true. But for everyone else, there are no real guarantees of success.

OK say all the men who think technology has all the answers. If there are no pills, what can the surgeons do for us? Well, never slow on the uptake, there's a major industry offering hair implants. Now this is exactly what you think it is. Rather like a farmer takes a seedling, bends over in a paddy field and sticks it into the ground where it will grow into rice, so the surgeon takes one or two follicles of hair and sticks them into your scalp. If three or four hairs as a single unit are transplanted, this can give a thicker appearance to the hair, assuming it grows.

Yes, that's right. There's no guarantee hair implants will grow. This could leave you with a double problem. You could have scarring in the parts of your scalp from which the hair was taken, and the same bald patches where the hair refused to grow. Add in the risks of infection and you have a procedure that requires thought before you agree. Oh, and the cost? This is set by the number of hairs you have transplanted. The average cost varies between $7,000 and $10,000. So this is expensive and not guaranteed.

Well, one thing is for certain. If you have male pattern baldness, Propecia is the more or less guaranteed cure. The drug has been through the formal clinical tests and has full FDA approval. Although there are some men who do not respond well, particularly if you have delayed starting the treatment until the hair loss was extensive. But when making your decision, remember one thing. Before a drug can be sold, it must be tested. There are no clinical trials or tests before surgeons launch a new technique. In the case of follicle grafts, there's absolutely no clinical evidence showing how effective the procedure is across all the different causes of hair loss and no evidence of the percentage of men who suffer adverse side effects. It seems you just have to trust surgeons to be able to do the right thing. Now it's your choice. With a confirmed diagnosis of male pattern baldness, do you let a surgeon replant hair follicles across your scalp, or do you buy Propecia online and swallow one every day.
