Here are some common Myths you mite want to look over in answering you question...
Male hair loss occurs because of something know as Androgenetic Alopecia, also know as "male pattern" baldness. It is caused by the effects of the male hormone dihydrotestosterone (DHT). Sometimes hair loss can begin fairly early in a young man's life, in his 20's. When this happens, a man's self confidence can be knocked substantially.

Here are the best common Myths...

Myth No 1. Hair loss only comes from the mother's side of the family. This means looking at the heads of your mum's uncle or dad and if they are baldies then chances are you will be too. The condition can actually be inherited from either parent, however the maternal side of the family does influence the condition slightly more than the paternal side of the family.

Myth No 2. Wearing hats cause hair loss. This is total codswallop and it's most likely an idea that was born in the military. Young men in the service had to wear hats and eventually showed of thinning hair or going bald. But the age that young men enter the military is also the age that male pattern hair loss usually begins.

Myth No 3. Male Pattern Baldness can be improved or prevented from a good nutritious diet. Unfortunately the foods you choose to eat have no bearing on the number of hairs on your head. That's not to say that certain nutritional deficiencies can't cause hair loss. For example iron, or iodine deficiencies.

Myth No 4. Circulation. Poor circulation around the hair follicle is often blamed for hair loss. However, experiments have proven that an increase in blood flow does not grow hair.

Myth No 5. Mites. This is a relatively new myth, but it's totally ridiculous, especially given that homeless people and those living in third world countries generally have full heads of hair. Mites and organisms do dwell on the scalp, but they do not east hair or cause loss baldness in any way.

Myth No 6. Stress Causes Hair Loss. Experts have never indicated that the most common form of baldness is linked in any way with emotional stress. Stress can, however, be the cause of alopecia, an autoimmune disease that causes hair loss in circular patches.

Myth No 7. Massage can stimulate hair growth. This is quite the opposite in fact, as vigorous massage can cause hair to break easily.

Myth No 8. Bald men are sexier and better lovers. Sorry bald men, but it's not your amazing testosterone levels that cause hair loss, but rather DHT, a testosterone derivative that causes hair follicles to shut down.

Myth No 9. Rubbing Marmite on your scalp promotes hair growth. No, no, no!
