If more proteins are synthesized, more hair strands are created. Plus, selenium also stimulates the regularity of your hair growth cycle, allowing anagen or growth follicles to produce hair strands on time. A 2019 scientific review on selenium stated selenium's role in mitigating the hair loss effects among a group of chemotherapy patients.
Abstract. This paper deals with a simplified multi-element profiling of inorganic arsenic, antimony, selenium and tellurium in the form of 75 As, 82 Se, 121 Sb and 125 Te by ICP-MS for amounts less than 10 µg L −1.Internal standards such as 72 Ge and 209 Bi were successfully used for the suppression of both influence of macro …
Due to the positive results from the NPC trial, the Selenium and Vitamin E Cancer Prevention Trial (SELECT) was undertaken in 35,000 healthy US men randomly assigned to 4 groups (selenium-−200 mcg/d from L-selenomethionine, vitamin E-−400 IU/d of all rac-alpha-tocopheryl acetate, selenium + vitamin E, and placebo).
