Recent studies have shown us what many have suspected for quite some time: zinc is involved in so many critical bio-chemical processes and right down to the cellular level that a deficiency -even slight- can have significant and even visible health consequences. Hair enthusiasts should take note that one of these unwanted consequences is thinning hair and a poorly performing hair growth cycle, something which so many of us struggle to explain. In the body zinc is in fact a building block of hair and a major player in protein synthesis, replication and structure. In our never-ending quest to explain the current epidemic of hair issues, could zinc be the answer?
