More hair? Less hair? Hair here but not there? For men and to a lesser extent for women, maintaining hair coverage on the head is an important issue. Balding or thinning of hair is commonly observed as androgenic alopecia or male pattern baldness, that is, hair loss associated with androgenic steroids. This trait is more common in Caucasians than other racial groups and about 35–40% males in the United States and Northern Europe experience hair loss with aging, whereas the figure is in the 20% range in Japan and Taiwan. Women also can experience this form of hair loss, more typically as thinning rather than complete loss. There are estimated to be about 100,000–150,000 hair follicles on the scalp. At any given time, roughly 90% are actively growing hair (anagen phase) while 10% are in a resting phase (telogen phase). Males tend to produce more “terminal” hairs, which are thicker and darker. Several factors decrease hair growth. One is atrophy of the hair follicle, which is associated with male pattern baldness.
Exposed children, protected parents; shade in playgrounds as a previously unstudied intervention field of cancer prevention

Around 40–50% of total exposure to solar UV radiation, experienced before the age of 60, occurs before the age of 20 (Green et al. 2011). In terms of preventing skin damage from UV radiation, childhood thus represents a key period of life (Green et al. 2011). Firstly, the occurrence of sunburn before puberty is associated with an increased risk of developed malignant melanomas later in life (Oliveria et al. 2006). Due to differences in hair type, the stem cells in the bulge region of hair follicles are usually not located as deeply in the skin of children (vellus hair) compared to adults (terminal hair) and are thus less protected against UV exposure (Volkmer and Greinert 2011). Secondly, due to developmental processes, children are not yet able to develop their own sense of risk awareness and to practice the typically recommended sun protection measures (Gregus 2006). Thirdly, their range of mobility is inherently limited so that they have to rely on external help if they wish to find alternatives to exposed playgrounds on sunny days (e.g. indoor play areas, sports halls).
