hair cleaning
One way to distribute the hair's natural oils through the hair is by brushing with a natural bristle brush. The natural bristles effectively move the oil from the scalp through to the hair's mid-lengths and ends, nourishing these parts of the hair. Brushing the scalp also stimulates the sebaceous gland, which in turn produces more sebum. When sebum and sweat combine on the scalp surface, they help to create the acid mantle, which is the skin's own protective layer. How do you know if your brushing your hair enough or too much? especially in terms of hygiene? — Preceding unsigned comment added by 110.151.0.85 (talk) 09:47, 16 April 2019 (UTC)

Untouched Russia
I've heard a few people mention certain untouched areas in eastern Russia. Are there any places in Russia that haven't been explored, at least by modern explorers? And which part of Russia is the most inhospitable to humans? déhanchements (talk) 19:48, 16 April 2019 (UTC)
