Higher intracellular calcium levels are shown to help with healthy development of the hair fibre.
Higher levels of calcium increase protein expressions that support keratin cell growth and maintenance. Calcium reducies protein misfolding events that can lead to impaired keratin cell development.
Get enough calcium in your diet – Consume calcium rich foods such as dairy foods, bread with fortified flour and green leafy vegetables such as spinach and curly kale. According to the NHS, adults aged 19-64 need around 700mg of calcium per day.
Check your vitamin D levels – One of the main functions of vitamin D is to increase calcium absorption from the intestines. According to Harvard Medical School, when you are low in vitamin D, you can only absorb around 10% of ingested calcium.
Eat a high zinc diet or take a supplement – Supplementing with zinc has been shown to increase levels of zinc by lowering the levels of vitamin D receptors on hair follicle membranes.
Zinc also helps the way cells use vitamin D to ensure maximum calcium absorption .
Top up your taurine – Taurine, a sulphur containing amino acid regulates calcium levels with a cell. Taurine can be obtained from the diet and in the presence of vitamin B6 (pyridoxine) can be synthesised from cysteine and methionine.
