Unlock Thicker, Fuller Hair: The 5 Essential Vitamins You Need

We all dream of having thick, long, healthy hair, yet often find ourselves sulking in the washroom over dullness, breakage, and thinning strands. In fact, around 50% of men and women experience premature hair thinning or hair loss by the age of 40. Do you know the real cause? It’s not just your hair products or pollution more often, it’s nutritional deficiencies. Hair health isn’t only about shampoos, oils, and serums; it’s deeply tied to what you feed your body, along with what you apply to your scalp. Let’s take a look at how these five key vitamins can boost hair growth and help you regain that long-lost thickness.

Vitamin A is an essential nutrient for hair growth and is known to promote sebum production, the natural oil produced by the sebaceous glands in the scalp. This sebum acts as a moisturiser, keeping the scalp hydrated, nourished, and protected from dryness or flakiness. You can get an adequate amount of vitamin A by adding carrots, eggs, kale, red bell peppers, and sweet potatoes to your diet.

Also known as ascorbic acid, vitamin C is rich in antioxidants that protect our hair from oxidative stress caused by free radicals and improve the overall structure of our mane. Its significant contribution lies in the production of collagen, which strengthens our hair strands and helps them maintain their volume. You can gain vitamin C from citrus fruits, bell peppers, berries, kiwis, tomatoes, and broccoli.

Vitamin D is important for creating new hair follicles. These follicles are essential for hair regrowth and maintain the quality and texture of our hair strands. Also known as the ‘sunshine vitamin’, many studies have shown that low levels of vitamin D can also result in conditions such as alopecia areata, which is a type of autoimmune-related hair loss issue. You can gain vitamin D by consuming egg yolks, fatty fish, oat milk, and almonds, and spending time in the sunlight.

Biotin is also known as vitamin B7, which promotes hair growth and thickness. What truly makes biotin stand out is its direct impact on keratin. It is a type of protein that makes up the structure of your hair. By supporting keratin production, biotin strengthens hair strands and also encourages healthier and more resilient hair texture. Biotin sources include salmon, nuts, seeds, legumes, almonds, eggs, and sweet potatoes.

Vitamin E protects our hair from environmental damage, which is caused by free radicals. These free radicals can lead to oxidative stress and can negatively affect our hair health, which leads to breakage, slow growth, and thinning as well. Vitamin E improves blood circulation to the scalp and encourages healthy hair growth. This vitamin is also known to nourish and repair damaged hair. You can consume nuts, seeds, spinach, olive oil, kiwi, and avocados for vitamin E.
