The explination is more complicated than you might think.
The reason most do not experience hair loss in the occipital area and around the ears is there are far less hormone receptors and smaller sebum glands. That is why the HT people transplant hair from that region. 98% of the population have the demodex. They are also practically impossible to irradicate. They are a contact mite. Every time your face, head or part of you body comes into contact with them they are transmited. Like head lice, they do not fly or jump. They crawl. Pillow pressure has nothing to do with how the mite travels. They can also live on your pillows and bed sheets for 52 hours before they die. If you cannot remove the yellowish stain from the pillow or bed linen, toss them and buy new. I find bleach and hot water removes the stain.
One in four women experience hair loss. They just hide it better than men. As hard as it is for men to loose their hair, it is devastating for women. With the exception of most of the men suffering from hair loss, society has accepted mens hair loss. The latest fashion statement? Shave your head. Not many women would consider this an alternative.
Hair loss differences in the sexes is some what different. As a woman enters menopause, as early as their mid 30's in my case, their chemical physiology changes. They start producing more of the male hormone DHT, hence the facial hair on my chinny chin chin.(eeewww). They also experience hormone fluxuations, power surges (hot flashes) lol, which produce more perspiration. Perspiration consists of moisture, salt and DHT rich oil which when left upon the scalp, produces a micro-thin, co-polymer layer adding to the buildup. With the aid of a cosmetic scope, she is able to see the layers of build up around the follicle. They stack upon each other looking similar to steps on a stairway. Women also loose their hair differently. Similar to wearing a hat, they loose the majority of hair from the ears up. It becomes so thin they wear their hair differently to cover the loss, use a topical cover like Topix or start wearing wigs.
Some women have very dry scalps. In their case, I find it's more of a DHT and build up problem. Once the build up is removed, the scalp has been stimulated and brings oxygen rich blood to the surface. New hairs start growing in follicles already occupied by hair, while the sebum plugs are being removed from clogged follicles. Everytime the toxic material within the follicle is removed, healing begins.
Women who are oily, tend to have the same issues men do with the demodex. Although I must say, the oily scalps tend to have a more lubricated follicle, allowing for the sebum mass to be extracted easier. The down side is, with more oil, there is more food for the demodex.
