Do hair, skin, and nail vitamins really work?

Many of us crave radiant, vibrant, and healthy looking hair, skin, and nails. And, whilst many people try to build the appearance of these tissues from the outside, the true key to healthy skin, beautiful hair, and strong nails is building them from the inside out, through good nutrition and key dietary supplements.

There are a huge and ever-growing range of skin, hair, and nail supplement products on the market, all claiming to provide glowing skin, luscious locks, and longer, stronger nails. But with so many to choose from, how can you even begin to choose the best ones for you? And do they even work?

Just like the rest of your body, you hair, skin and nails can all benefit from proper nutrition. Of course, the best way to get good nutrition is to maintain a well-balanced diet. However, despite having the best of intentions, this isn’t always possible. And that’s where vitamins and supplements that have been specially formulated to target the health of hair, skin, and nails can help.

The key to finding hair, skin, and nail supplements that really work is to find the right ingredients.

Here’s our guide to the most effective vitamins for hair, skin, and nails:


Also known as vitamin H, Biotin encourages the production of protein for nail growth. It also stimulates new hair growth and promoted a healthier texture by protecting against dryness and scalp flaking, and increasing the elasticity of the hair’s cortex in order to prevent breakage.

Biotin can be beneficial to those with thinning hair or brittle nails.

Vitamin B

Vitamin B acts as an antioxidant for the skin, assisting in the removal of bacteria and helping to clear up acne and other skin concerns. It also helps to balance out testosterone levels whilst helping to reduce stress and address the adrenal glands.


The mineral zinc is crucial for healthy cell division. This means that the parts of your body that rapidly produce, such as your hair and your nails, need a constant flow of zinc in order to generate strong cells.

When it comes to hair, zinc can help prevent lifeless hair and hair loss. It can also help to heal skin lesions, making it helpful in the treatment of skin conditions such as acne, psoriasis, and dermatitis.

If you’re experiencing slow-growing, splitting, or discoloured nails, you could well have a zinc deficiency.

Omega-3 Fatty Acids

Omega-3 fatty acids help to keep your levels of keratinocytes healthy, promoting soft skin, sleek, strong hair, and shiny nails.

Vitamin A

Known as retinol in the beauty industry, vitamin A is known for its anti-aging, acne-healing abilities. A lack of vitamin A can lead to scaly, dry skin and the loss of hair.


Keratin is a key ingredient for hair, skin, and nails supplements. Keratin is a protein in our bodies that supports the structure of skin, nails, and hair. Low levels of Keratin (caused by a poor diet or simply by aging), lead to dry, wrinkled skin, brittle nails, and fragile or thinning hair.
