The Best Stack for Hair + Nails

Hair and nails are more than just aesthetic features, they’re indicators of our overall health. Hair is made of keratin, a fibrous protein that grows from follicles in the scalp, while nails are also composed of keratin, growing from a matrix beneath the cuticle. Both are dependent on the health of the cells that produce them and are affected by internal and external factors. Healthy hair and nails contribute to confidence, protection (e.g., nails protecting fingertips), and even thermal regulation.

However, poor diet, stress, hormonal imbalances, ageing, and environmental damage can lead to brittle nails, thinning hair, or even hair loss. Symptoms like split ends, slow nail growth, or discolouration are warning signs that these structures may not be getting the nutrients they need. Understanding the science of hair and nail growth is crucial to targeting these issues effectively.

Hair and nail health rely heavily on the availability of nutrients like proteins, vitamins, and minerals. Proper collagen production, hydration, and antioxidant protection are essential to reduce oxidative damage, strengthen keratin bonds, and support growth cycles. Below, we explore the best supplements to optimise hair and nail health, their benefits, and how they work.

Collagen

Collagen is the most abundant protein in the body, providing structural support for skin, hair, nails, and connective tissues. It’s composed of amino acids like glycine, proline, and hydroxyproline that strengthen keratin and improve the elasticity of hair and nails. Collagen supplementation stimulates fibroblasts (cells that produce collagen), promoting thicker hair and stronger nails. Hydrolysed collagen peptides are particularly effective due to their high bioavailability.

Benefits:

• Strengthens hair and nails

• Promotes elasticity and hydration

• Reduces hair breakage and split ends

• Supports overall skin health

Silica

Silica, a trace mineral found in foods like horsetail and bamboo, is crucial for collagen synthesis. It helps strengthen hair shafts and nail beds by supporting the production of keratin. Silica also improves hydration and elasticity, reducing brittleness. This mineral is particularly effective in maintaining thick, shiny hair and resilient nails over time.

Benefits:

• Enhances collagen production

• Reduces brittleness in hair and nails

• Promotes shine and strength

• Supports connective tissue health

Biotin

Biotin, also known as vitamin B7, is a water-soluble vitamin that plays a key role in keratin production. It’s one of the most researched vitamins for improving hair and nail strength. Biotin boosts the metabolism of proteins, fats, and carbohydrates, providing the nutrients necessary for healthy growth cycles. Deficiency in biotin often leads to brittle nails and hair loss.

Benefits:

• Strengthens hair and nail keratin

• Improves hair thickness and growth

• Reduces splitting and brittleness

• Boosts cellular energy metabolism

MSM (Methylsulfonylmethane)

MSM is a sulphur-rich compound that supports keratin and collagen formation. Sulphur is a key building block for strong, flexible hair and nails. MSM also has anti-inflammatory properties, reducing scalp inflammation that may inhibit hair growth. By improving circulation and collagen production, MSM enhances the delivery of nutrients to hair follicles and nail beds.

Benefits:

• Supports keratin and collagen production

• Improves hair and nail resilience

• Reduces scalp inflammation

• Boosts nutrient delivery to follicles

Zinc

Zinc is an essential mineral that plays a critical role in cell division and tissue repair, both vital for healthy hair and nail growth. It helps regulate oil production on the scalp, preventing dandruff and hair loss. Zinc’s antioxidant properties also protect hair and nails from environmental damage, such as pollution and UV exposure.

Benefits:

• Promotes hair and nail growth

• Prevents hair thinning and shedding

• Regulates scalp health

• Protects against oxidative stress

Horsetail Extract

Horsetail extract is a natural source of silica and antioxidants. It strengthens hair and nails while improving elasticity. Horsetail also contains selenium, which supports hair growth and scalp health by encouraging the regeneration of follicles. It’s particularly beneficial for reducing breakage and improving shine.

Benefits:

• Strengthens and fortifies hair and nails

• Promotes shine and elasticity

• Supports scalp and follicle health

• Provides antioxidant protection

He Shou Wu (Polygonum multiflorum)

A traditional Chinese herb, He Shou Wu is renowned for its ability to promote hair growth and delay greying. It nourishes the scalp, strengthens hair roots, and enhances circulation. Rich in antioxidants and trace minerals, this adaptogen supports both hair and nail health by reducing oxidative damage and balancing hormones that affect growth cycles.

Benefits:

• Stimulates hair growth and reduces shedding

• Delays premature greying

• Strengthens hair roots and nails

• Balances hormone-related hair loss

Omega-3 Fatty Acids

Omega-3 fatty acids, found in fish oil and flaxseed, are essential for maintaining scalp health and reducing inflammation. They nourish hair follicles, promoting stronger, shinier hair. Omega-3s also improve nail strength by reducing brittleness and boosting hydration. Their anti-inflammatory properties combat conditions like psoriasis that can affect the scalp and nails.

Benefits:

• Nourishes scalp and hair follicles

• Reduces inflammation

• Improves hair shine and nail strength

• Supports overall skin health

Folic Acid

Folic acid, or vitamin B9, supports cell division and tissue growth, both of which are essential for healthy hair and nails. By aiding in the production of red blood cells, folic acid ensures that hair follicles and nail beds receive adequate oxygen and nutrients. It’s particularly effective in reducing hair thinning and improving nail resilience.

Benefits:

• Promotes cell growth and tissue repair

• Reduces hair thinning

• Improves nail strength and resilience

• Enhances nutrient delivery to follicles

Vitamin E

Vitamin E is a powerful antioxidant that protects hair and nails from oxidative damage caused by free radicals. It improves circulation to the scalp and nail beds, encouraging growth and strength. Vitamin E also hydrates and conditions hair and nails, reducing dryness and breakage.

Benefits:

• Protects against oxidative damage

• Improves scalp and nail bed circulation

• Reduces dryness and breakage

• Enhances overall hydration

Conclusion

Maintaining strong, healthy hair and nails requires a combination of the right nutrients, proper hydration, and minimising environmental damage. This stack of supplements offers a powerful way to address common issues like brittleness, thinning, and slow growth. When combined with a balanced diet and a good self-care routine, these ingredients can help you achieve luscious locks and resilient nails.
