Hair health is not a single-ingredient problem. It is a nutritional ecosystem — and Only Hair was designed to address it as one. Ten carefully chosen ingredients, each with a distinct role: the vitamins and minerals that carry EU and UK authorised health claims for hair maintenance, working alongside some of the most actively researched botanicals in hair nutrition science.

Most hair supplements give you biotin. Only Hair gives you biotin at a meaningful dose — plus selenium, zinc, copper, niacin, Vitamin E, horsetail extract, nettle leaf, saw palmetto and inositol. Because your hair deserves more than a single ingredient and a marketing claim.

THE DODIHEALTH DIFFERENCE

Ten ingredients. Two distinct roles. The Only Hair formula is built around a clear principle: combine the nutrients with authorised claims for hair maintenance with the most actively researched botanicals in hair nutrition science — and let them work together.

The Nutrition Layer

Biotin, selenium, zinc, copper, niacin and Vitamin E — six ingredients carrying EU and UK authorised health claims relevant to the maintenance of normal hair, skin, nails and cell protection from oxidative stress.*

The Botanical Layer

Horsetail extract, saw palmetto, nettle leaf and inositol — four of the most researched botanicals in hair nutrition science, included for their educational interest and the growing body of literature exploring their relationship with hair health.

Sugar-free. Trusted by 100+ UK pharmacies. Chosen by those who take their hair health as seriously as the rest of their nutrition.

10 active ingredients — a complete hair nutrition formula, not a single-ingredient supplement
Biotin at 1800% NRV — one of the highest biotin doses available in gummy form
Selenium at 184% NRV — contributes to maintenance of normal hair*
Zinc — contributes to maintenance of normal hair and nails*
Copper — contributes to normal hair pigmentation*
With saw palmetto, horsetail, nettle leaf and inositol — the most researched botanical layer in hair nutrition science
Pharmaceutical-grade gummy formula — designed for smart, consistent delivery
Sugar-free, trusted by 100+ UK pharmacies
EU and UK authorised health claim

Ingredient Explainer Cards

Biotin (900mcg — 1800% NRV) — Why we chose this dose deliberately

What it is: Biotin, also known as Vitamin B7 or D-Biotin, is a water-soluble B vitamin essential for the metabolism of fatty acids, amino acids and glucose. It is found naturally in eggs, liver, nuts and legumes. The EU/UK NRV for biotin is 50mcg. Only Hair delivers 900mcg — 1800% NRV.

Why it is in this formula: Biotin carries EU and UK authorised health claims for the maintenance of normal hair, skin and nails. But here is something worth knowing: we deliberately chose 900mcg rather than the 5,000mcg or 10,000mcg doses that dominate the market. Biotin is water-soluble — anything the body cannot use is excreted, so higher doses do not mean better results. More importantly, very high-dose biotin supplementation (typically 5mg and above) is documented to interfere with laboratory blood tests including thyroid function, troponin and hormone assays. The MHRA has issued a specific Drug Safety Update on this risk. Our 900mcg sits well below this threshold — meaningful and effective, without the risks associated with megadosing.

Selenium (101mcg — 184% NRV)

What it is: Selenium is an essential trace mineral with antioxidant properties, found naturally in Brazil nuts, fish and wholegrains. The EU/UK NRV is 55mcg. Only Hair delivers 101mcg — 184% of the NRV. Note: the UK upper safe limit for selenium is 350mcg per day from all sources combined.

Why it is in this formula: Selenium carries EU and UK authorised health claims for the maintenance of normal hair, normal nails, and the protection of cells from oxidative stress. It is a component of selenoproteins, which play an important role in antioxidant defence — providing a layer of cellular protection for hair follicles alongside the Vitamin E in this formula.

Zinc (6mg from Zinc Citrate — 1.8mg elemental, 18% NRV)

What it is: Zinc is an essential trace mineral involved in hundreds of enzymatic reactions. Found naturally in meat, shellfish and legumes. The EU/UK NRV for elemental zinc is 10mg. Only Hair delivers 1.8mg elemental zinc (18% NRV) from zinc citrate — a highly bioavailable form.

Why it is in this formula: Zinc carries EU and UK authorised health claims for the maintenance of normal hair and nails, normal skin, and normal testosterone levels in the blood. Zinc plays a role in protein synthesis and cell division — processes directly relevant to hair follicle function and hair fibre production.

Copper (1mg — 100% NRV)

What it is: Copper is an essential trace mineral found naturally in shellfish, nuts and organ meats. The EU/UK NRV is 1mg. Only Hair delivers 1mg — 100% of the NRV.

Why it is in this formula: Copper carries EU and UK authorised health claims for normal hair pigmentation and maintenance of normal connective tissues. Copper is involved in the activity of tyrosinase, the enzyme responsible for melanin production — the pigment that gives hair its colour.

Niacin / Vitamin B3 (16mg NE — 100% NRV)

What it is: Niacin (Vitamin B3) is a water-soluble B vitamin found naturally in meat, fish, legumes and wholegrains. It exists in two forms: nicotinic acid and nicotinamide. The EU/UK NRV is 16mg Niacin Equivalent (NE). Only Hair delivers 16mg NE — 100% of the NRV.

Why it is in this formula: Niacin carries EU and UK authorised health claims for the maintenance of normal skin and normal energy-yielding metabolism. A healthy scalp environment is an important context for hair health, and the skin-maintenance claim for niacin is directly relevant to this formula's role in supporting the scalp.

Vitamin E (12mg — 100% NRV)

What it is: Vitamin E (as d-alpha-tocopherol acetate) is a fat-soluble antioxidant found naturally in nuts, seeds and vegetable oils. The EU/UK NRV is 12mg alpha-TE. Only Hair delivers 12mg — 100% of the NRV.

Why it is in this formula: Vitamin E carries an EU and UK authorised health claim for the protection of cells from oxidative stress. It works alongside selenium to provide antioxidant protection within this formula. Oxidative stress is studied for its relationship with hair follicle health.

Horsetail Extract (300mg, std. 7% silica)

What it is: Horsetail (Equisetum arvense) is one of the plant kingdom's richest natural sources of silica, standardised here to 7% silica content — providing approximately 21mg of silica per serving. Silica is a trace mineral and a natural component of hair fibre, connective tissue and nails.

Why it is in this formula: Horsetail extract is included for its silica content and its long-standing place in hair and nail nutrition research. Silica is studied for its structural role in hair fibre and its potential relationship with hair strength and growth rate. No standalone EU/UK authorised health claim exists for horsetail or silica.

Saw Palmetto Extract (100mg)

What it is: Saw palmetto (Serenoa repens) is a small palm plant native to the southeastern United States. Its berry extract has been studied extensively in the context of hair health, particularly for its relationship with 5-alpha reductase — the enzyme responsible for converting testosterone into dihydrotestosterone (DHT). DHT is the androgen most closely associated with androgenetic hair loss in both men and women.

Why it is in this formula: Saw palmetto is one of the most actively researched botanicals in hair nutrition science. A 2020 systematic review of 7 studies found 60% improvement in hair quality and 83.3% of participants showing increased hair density in investigator assessment. A 2023 randomised placebo-controlled trial found oral saw palmetto reduced hair fall by up to 29% vs placebo. No EU/UK authorised health claims exist for saw palmetto. Note: saw palmetto may interact with blood-thinning medications and hormone-sensitive conditions — see Warning section.

Nettle Leaf Extract (100mg)

What it is: Stinging nettle (Urtica dioica) leaf extract is derived from one of the most nutritionally dense plants in traditional European herbal medicine. It contains natural silica, iron, zinc, and a range of polyphenols and flavonoids.

Why it is in this formula: Nettle leaf extract is included for its nutritional density and its place in the growing body of hair nutrition research. It is studied for its relationship with scalp health, its mineral content, and its potential influence on the hair follicle environment. No EU/UK authorised health claims exist for nettle leaf.

Inositol (10mg)

What it is: Inositol is a naturally occurring carbohydrate compound found in foods including fruits, beans, grains and nuts. It is sometimes referred to as Vitamin B8, though it is not technically a vitamin as the body can synthesise it. It is involved in cellular signalling and membrane function.

Why it is in this formula: Inositol is included for its interest within nutritional research into hair health and scalp environment. It is studied for its role in cellular signalling pathways relevant to hair follicle biology. No EU/UK authorised health claims exist for inositol.

Mango-flavoured & easy to take daily

Take two Only Hair gummies daily with a meal to support your hair from within. These gummies are designed to be part of your daily routine — morning or evening, whatever works for you. Hair nutrition responds to consistency, not intensity. The ten ingredients in this formula work together every day: the authorised nutrients laying the nutritional foundation for normal hair maintenance, and the botanical layer contributing the most researched plant ingredients in hair science. Your hair grows from the inside out. So does the solution.

Timing

Daily Ritual

Take 2 gummies daily, preferably with your largest meal of the day. Consistent daily use is what makes the difference — hair nutrition builds over time, not overnight. Make it part of your routine and give it the time it deserves.

Usage Guidelines

Adults: Take two gummies per day. For individuals aged 12 to 16: One gummy per day may be taken under parental supervision, but only after consultation with a healthcare professional. Not suitable for children under 12 years of age. Do not exceed the recommended daily intake. Discontinue use if any adverse effects occur. For best results, consistent use over at least 3 months is recommended. Food supplements should not be used as a substitute for a varied, balanced diet and healthy lifestyle.

Storage and Safety Precautions

Ensure DodiHealth Vitamin Gummies are stored in a dry and cool environment, below 21°C, and keep them out of the reach of children. Excessive consumption may result in a laxative effect. Do not surpass the recommended daily dosage. If you are pregnant, breastfeeding, taking medications, or have underlying health conditions, consult a healthcare professional before use.

Only Hair FAQs

How long does it take to see results with Only Hair?

Hair grows at roughly 1cm a month and moves through natural growth cycles, so any hair nutrition supplement takes time. We'd suggest giving it at least three months of consistent daily use before you judge it, and six months is a fairer window still.

Zinc and selenium contribute to the maintenance of normal hair, and biotin contributes to the maintenance of normal skin and hair. Those nutrients work with your hair's own cycle rather than overriding it, which is why patience matters more here than with most supplements.

Consistency is what counts. Two gummies daily, without skipping, gives the formula its best chance.

Why does Only Hair contain saw palmetto, and is it safe for women?

Saw palmetto is a traditional botanical with a long history of use, included in Only Hair at 100mg alongside the six vitamins and minerals that carry authorised roles in hair and skin.

It's generally well tolerated by both men and women. That said, saw palmetto can influence hormone metabolism, so if you're pregnant, breastfeeding, taking hormone therapy or the contraceptive pill, or have a hormone-sensitive condition, please speak to your doctor or pharmacist before taking it.

If you're unsure whether it's right for you, your pharmacist is the best person to ask. Many of the pharmacies that stock us can advise in person.

Why is the biotin dose 900mcg and not higher? Many other supplements use 5,000mcg or more.

This is a deliberate formulation choice. Biotin is water-soluble, meaning anything your body cannot use is simply excreted. Higher doses do not mean better results. More importantly, very high-dose biotin supplementation — typically at 5mg (5,000mcg) and above — is documented by the MHRA to interfere with certain laboratory blood tests, including thyroid and hormone assays. Our 900mcg delivers 1,800% of the Nutrient Reference Value — a meaningful, effective dose that sits well within the range where your body can actually use it, without the risks associated with megadosing. We chose smart over excessive.

Can I take Only Hair alongside other dodiHEALTH products?

Yes, in most cases. Only Hair is formulated as a standalone daily hair nutrition product. We recommend taking Collagen Activate also for support, but not necessary to see the benefits. Most people do as the ultimate beauty care routine. If you have any concerns, our team is happy to help.

What is the difference between the Nutrition Layer and the Botanical Layer in Only Hair?

Only Hair is built around two distinct ingredient groups. The Nutrition Layer consists of six vitamins and minerals — biotin, selenium, zinc, copper, niacin and Vitamin E — each carrying EU and UK authorised health claims relevant to hair, skin and cell health. These are the regulated, evidence-based nutrients that form the nutritional foundation of the formula. The Botanical Layer consists of four plant-based ingredients — horsetail extract, saw palmetto, nettle leaf and inositol — included for their growing body of research in hair nutrition science. Botanical health claims are not currently authorised under EU or UK law, so these are included for their educational and nutritional interest rather than as regulated claims.

Is Only Hair suitable for vegans and is it free from common allergens?

Yes — Only Hair is vegan-friendly and sugar-free. It does not contain gluten, dairy or artificial colours. As with all our products, it is manufactured in a pharmaceutical-grade facility. If you have specific allergen concerns, please check the full ingredient list on the product label or contact our team directly.
