Nutrition plays a critical role in hair health. While no supplement can replace medical treatment for significant hair loss, the right vitamins and minerals can support the hair growth cycle and prevent deficiency-related shedding.
Essential Vitamins for Hair Growth
1. Biotin (Vitamin B7)
Perhaps the most well-known hair supplement. Biotin is essential for keratin production, the protein that makes up your hair. Deficiency is rare but can cause hair thinning and brittle nails. Recommended dose: 2,500–5,000 mcg/day.
2. Vitamin D
Vitamin D receptors are found in hair follicles, and deficiency is strongly linked to alopecia areata and telogen effluvium. Get a blood test to check your levels, most Indians are deficient. Recommended dose: 1,000–4,000 IU/day.
3. Iron
Iron deficiency (anaemia) is one of the most common causes of hair loss in women. Ferritin levels (stored iron) below 70 ng/mL are associated with significant hair shedding. Best sources: lean red meat, spinach, lentils, and fortified cereals.
4. Vitamin B12
B12 is crucial for red blood cell production, which delivers oxygen to the scalp and hair follicles. Vegetarians and vegans are at high risk of deficiency. Supplement with 1,000 mcg/day if levels are low.
5. Zinc
Zinc plays a role in hair tissue growth and repair. It also keeps the oil glands around follicles working properly. Both deficiency and excess can cause hair loss, always test before supplementing.
Important: Before starting any supplement, get a blood test to identify actual deficiencies. Supplementing vitamins you don't need is wasteful and can sometimes be harmful. Always consult a dermatologist or physician.
