Hair loss and slow growth are common concerns. While a balanced diet is crucial, supplements can provide extra support. Here are 5 of the best, backed by science, to boost your hair health. Remember to consult your doctor before starting any new supplement regimen.
Biotin (Vitamin B7)
What it is: Biotin is a B-vitamin essential for keratin production – the protein that makes up hair. Deficiency, though rare, can lead to hair thinning and brittle nails.
Benefits: Improves hair strength, reduces breakage, and may promote growth. Often found in shampoos, but oral supplementation is more effective for deficiencies.
Dosage: 2.5-5mg daily is generally recommended. Excessive intake isn’t usually harmful as it’s water-soluble, but can interfere with lab tests.
Vitamin D
What it is: Vitamin D plays a role in hair follicle cycling. Low levels have been linked to alopecia (hair loss).
Benefits: Helps create new hair follicles, potentially reversing hair loss. Important for overall health too!
Dosage: Get your Vitamin D levels checked. Supplementation typically ranges from 1000-2000 IU daily, but depends on your current levels.
Iron
What it is: Iron deficiency (anemia) is a significant cause of hair loss, especially in women. Iron carries oxygen to hair follicles.
Benefits: Restores oxygen supply to follicles, promoting growth and reducing shedding; Important for energy levels too.
Dosage: Get your iron levels tested! Supplementation should be guided by a doctor, typically 18mg daily for deficiency.
Zinc
What it is: Zinc is involved in hair tissue growth and repair. It also helps keep the oil glands around follicles working properly.
Benefits: Reduces hair shedding, improves follicle health, and may combat dandruff.
Dosage: 8-11mg daily is the recommended daily allowance. Excessive zinc can interfere with copper absorption, so don’t overdo it.
Vitamin C
What it is: Vitamin C is a powerful antioxidant that protects against free radical damage, which can hinder hair growth. It also aids iron absorption.
Benefits: Boosts collagen production (important for hair structure), protects follicles, and enhances iron uptake.
Dosage: 75-90mg daily is sufficient for most. Higher doses (up to 2000mg) are generally safe, but may cause digestive upset.
