According to trichologist Philip Kingsley, hair plugs are not a new concept: they were first created in 1956 by an American dermatologist called Norman Orentreich.
A dog may be lightly sabled, with just a scattering of black-tipped hairs over the withers, to one who is so heavily sabled that from a distance he almost appears black.
Men also have hair dryers and, if they suffer from baldness, they use a growth stimulator, buy hairpieces, or have hair transplanted from the hirsute part of the scalp to the bare areas.
