Minerals play an essential role in our biological processes. Zinc in particular, is implicated in the division of hair follicle cells. Zinc is also involved in the maintenance of our hormonal balance. For these reasons, it’s presence is crucial to healthy hair growth. Zinc deficiency deteriorates the Keratin, a protein found in our hair follicles, leading to hair loss. Other symptoms of zinc deficiency: white spots on the nails, skin rash or acne, a weak immune system, loss of appetite, fatigue, diarrhea, and hypothyroidism.

In 2008, Researcher Nina van Beek and her colleagues published the first evidence of how thyroid hormones (T3 and T4) modulates multiple hair functions. From the prolongation of the Anagen phase to the stimulation of keratinocyte proliferation and hair pigmentation. Hypothyroidism, a condition characterized by lower levels of thyroid hormones, would definitely be detrimental to your hair. Hypothyroidism has also been described as one symptom for zinc deficiency.
Zinc can support your hair growth by sustaining the keratin (hair protein) and the multiplication of your hair cells. Zinc maintains our hormonal balance, preventing hypothyroidism that has been proved to be damaging for the hair growth cycle.

Adequate supplementation of zinc is required to achieve your hair goals. The recommended daily intake of Zinc may vary with age and health status. Women from 18 years old should take a maximum of 22 mg daily. Pregnant or nursing women and women under any therapeutical regimen should talk their Doctor or Pharmacist before taking Zinc supplements. They will advise you on the strength and therapy duration that are appropriate for you. Having a balanced diet is a good way to maintain your zinc level and prevent zinc deficiency.
