Search the herb "saw palmetto" on the web. Saw Palmetto is a herb that works against male pattern baldness, and it protects the prostate. It does not have any side effects. Saw Palmetto does not actually include any hormones like prescription drugs, so it is much much safer and natural.

Saw Palmetto extracts are sold by many companies in capsule form. Look for a quality brand when buying. The brand SOLGAR seems to be my favorite for this reason.

Rogaine and Minoxidil are topically applied, but don't work on all areas of the scalp. Propecia is a drug, helps the prostate, but it is expensive. In all cases, once you stop the treatment, your hairloss continues.

There's some evidence that vitamin supplements can help. I don't make one for hair, but there are many on the market that may help.
