Zinc
Also known as: Zinc gluconate, Zinc picolinate
Zinc is an essential trace mineral critical for hair growth, immune function, and wound healing. Zinc deficiency is associated with hair loss, skin problems, and impaired immune function. Supplementation may restore hair growth in deficient individuals and support overall scalp health.
How It Works
Zinc is a cofactor for over 300 enzymes involved in protein synthesis, DNA replication, and cell division—all essential for hair growth. It regulates the hair growth cycle, supports sebaceous gland function, and maintains the integrity of the hair follicle. Zinc also has anti-inflammatory and antioxidant properties that protect scalp tissue.
Key Benefits
Essential for hair follicle development and cycling
Supports protein synthesis for hair structure
Reduces scalp inflammation and sebum production
Supports immune function
May reverse hair loss associated with deficiency
Promotes wound healing in scalp tissue
Clinical Evidence
Zinc and Hair Loss: A Clinical and Biochemical Study
Rushton DH, Norris MJ, Dover R, Bussey D, Gilkes JJ, De Brouwer B • International Journal of Dermatology (1990)
Study of 312 patients with hair loss found that 26% had zinc deficiency. Zinc supplementation (25-50 mg daily) in deficient patients resulted in significant hair regrowth within 3-6 months.
Zinc Status and Hair Loss in Women
Kil MS, Kim CW, Kim SS • Annals of Dermatology (2013)
Analysis of 312 women with androgenetic alopecia found significantly lower serum zinc levels compared to controls. Zinc supplementation improved hair growth in deficient individuals.
The Role of Micronutrients in Hair Loss: A Review
Almohanna HM, Ahmed AA, Tsatalis JP, Tosti A • Dermatology Practical & Conceptual (2019)
Comprehensive review identified zinc deficiency as a modifiable risk factor for hair loss, with supplementation showing benefits particularly when combined with other micronutrients.
Dosage Recommendations
Hair loss with zinc deficiency
Dosage: 25-50 mg elemental zinc daily
Duration: 3-6 months minimum
Notes: Take with food to improve absorption and reduce nausea. Monitor copper levels with long-term use.
Hair loss prevention
Dosage: 15-25 mg daily
Duration: Ongoing
Notes: RDA for adult women is 8-11 mg daily. Higher doses should be used under medical supervision.
Severe deficiency
Dosage: 50-100 mg daily
Duration: 3 months, then reassess
Notes: High doses require medical supervision and copper monitoring to prevent copper deficiency.
Safety Profile
Zinc is safe at recommended doses. Excessive intake (>150 mg daily long-term) can cause copper deficiency, leading to neurological problems and anemia. Acute toxicity from very high doses can cause nausea, vomiting, and headache.
Important Considerations
Interactions
- • May reduce absorption of certain antibiotics and bisphosphonates
- • Can interfere with copper absorption at high doses
- • May reduce effectiveness of certain vaccines
Contraindications
- • Individuals with copper deficiency
- • Those taking certain medications (check with healthcare provider)
- • Pregnancy: Use only at recommended doses
