Register and Style. Academic writing has a level of formality, and it is sometimes difficult for the non-native speaker of English to recognise the differences in register and style of the language. The section covers some of the differences in style and register. Introduction.
B Vitamins. The B vitamins are vital in maintaining healthy hair and nails and can be taken in supplement form or by eating beans, eggs or berries. Vitamins help promote healthy hair growth.
Specific vitamin and mineral deficiencies like iron or vitamin B12 may be diagnosed by blood tests and treated. Multiple vitamins, including biotin, have been promoted for hair growth, but solid scientific studies for many of these claims are lacking. While taking biotin and other supplements marketed for hair, skin, and nails probably won't worsen anything, it may also not necessarily help the situation. Therefore, advertised hair-regrowth supplements should be approached with mild caution.
