whats the main hair loss cause
There are many reasons associated with hair loss. Stress, illness, genetics, chemicals, radiation, aging and diet. Certainly some of the reasons listed are a cause for hair loss but usually only temporary. The hair starts to grow back again after whatever condition was causing the hair loss subsides.
The most common hair loss cause is by far dht. Dht is a hormone emmited by testesorone which plays havoc with hair follicles when its not being neutralized. Our genetic programming determines how and when the dht imbalances occur and this is where the gene tie to hair loss comes in. Even if there is no hair loss in your family and your dna is hard coded this way you will suffer from hair loss.
The good news is this condition can be prevented by treating the dht prolefiration.
