Renfort Cheveux
Everyday beauty-from-within support
Renfort Cheveux is a multi-ingredient supplement designed to support hair, skin and nail nutrition. The formula combines key micronutrients with botanical and silicon sources commonly used in beauty routines. It is intended for consistent daily use as part of a balanced diet and healthy lifestyle.
Core nutrients for hair, skin and nails
D-biotin is included as a central beauty nutrient, often used to support normal keratin-related nutrition. Zinc is provided as zinc citrate, a well-known supplemental form used to help meet daily zinc needs. Selenium is supplied as L-selenomethionine, an organic selenium form commonly used in food supplements.
Silicon-focused components
The formula includes Urtica dioica L. leaf extract (10:1) standardized to 1% silicon, alongside a silicic acid ingredient that also contributes silicon. These components are often used in products that focus on structural-support nutrients. Together, they complement the biotin and mineral profile without relying on a single nutrient alone.
Food-based support from brewer’s yeast
Brewer’s yeast is included as a traditional food-derived ingredient used in many beauty and general wellness formulas. It provides a natural nutrient matrix that can complement targeted micronutrients. Because it is explicitly stated to contain gluten and sulphites, it may not be suitable for everyone.
Taste, texture and manufacturing aids
Xylitol and natural flavour are used to improve palatability. Microcrystalline cellulose supports tablet or powder processing as a filler, while vegetable magnesium stearate helps with flow and anti-caking during manufacturing. Natural beetroot red colouring is included for appearance.
How the ingredients work together
Biotin, zinc and selenium form the core micronutrient trio for hair, skin and nail maintenance. Silicon sources add a complementary structural-support angle that is commonly paired with beauty nutrients. For best results, use consistently and ensure overall dietary protein and micronutrient intake are adequate.

| Title | Description |
|---|---|
| Gluten sensitivity or coeliac disease – High Risk | Brewer’s yeast is explicitly stated to contain gluten, which may be unsuitable for individuals who must avoid gluten. |
| Sulphite sensitivity/asthma triggered by sulphites – High Risk | Brewer’s yeast is explicitly stated to contain sulphites, which can be problematic for sulphite-sensitive individuals. |
| Pregnancy – Medium Risk | High-dose biotin and trace minerals should be used in pregnancy only with professional advice to ensure appropriate total daily intake. |
| Breastfeeding – Medium Risk | Use during breastfeeding should be discussed with a healthcare professional due to concentrated micronutrients and botanical extract use. |
| Thyroid conditions – Medium Risk | Selenium intake can be relevant to thyroid nutrition, so people with thyroid disorders should seek advice before use. |
| Kidney impairment – Medium Risk | Mineral handling may be altered in kidney disease, so zinc/selenium supplementation should be supervised. |
| Known allergy to nettle (Urtica dioica) or botanicals – Medium Risk | Individuals with plant allergies may react to nettle leaf extract. |
| Title | Description |
|---|---|
| Gastrointestinal discomfort – Medium Risk | Zinc citrate and yeast-based ingredients may cause nausea, stomach upset, or abdominal discomfort in sensitive users. |
| Loose stools or gas – Medium Risk | Xylitol can cause bloating or laxative effects, especially at higher intakes or in sensitive individuals. |
| Metallic taste – Low Risk | Zinc supplements can sometimes cause a transient metallic taste. |
| Skin rash or itching – Low Risk | Botanical extracts or yeast may trigger mild hypersensitivity reactions in susceptible individuals. |
| Title | Description |
|---|---|
| Tetracycline antibiotics – High Risk | Zinc can reduce absorption of tetracyclines, so dosing should be separated by several hours. |
| Quinolone antibiotics – High Risk | Zinc can bind certain quinolones and reduce absorption; separate administration times. |
| Levothyroxine – Medium Risk | Minerals such as zinc may interfere with thyroid hormone absorption; take at different times if used. |
| Penicillamine – Medium Risk | Zinc may reduce penicillamine absorption, so timing separation is typically recommended. |
| Diuretics (long-term use) – Low Risk | Some diuretics can affect mineral status; combined use may warrant monitoring of zinc and other minerals. |
| Lab test interference (biotin) – Medium Risk | Biotin can interfere with certain immunoassay lab tests; inform healthcare providers and consider pausing before testing if advised. |

Hair, Skin & Nails
Designed to support the maintenance of hair, skin and nail quality using a combination of D-biotin, zinc (as zinc citrate) and selenium (as L-selenomethionine). Nettle leaf extract (Urtica dioica L., 10:1) and added silicon sources contribute structural-support nutrients often used in beauty-from-within routines. Suitable for people looking to support normal keratin-related nutrition and everyday appearance goals.
Hair
Targets hair-focused nutrition with biotin, zinc and selenium, nutrients commonly included in formulas for normal hair maintenance. Silicon from nettle extract (1% silicon) and silicic acid provides an additional mineral-structure angle often used in hair-care supplement stacks. This use case is most relevant for people seeking nutritional support during periods of lifestyle stress, seasonal changes, or cosmetic routines.
Skin Health
Supports general skin nutrition through zinc and selenium, which contribute to normal cellular protection processes, alongside biotin for normal skin maintenance. Brewer’s yeast adds a food-based nutrient matrix that is often used in beauty supplements. This is a supportive, whole-formula benefit rather than a single-ingredient focus.
Nail Health
Provides nutrients commonly used for nail maintenance, especially biotin and zinc, with supportive trace selenium. Silicon sources (nettle extract and silicic acid) are included as structural-support components often paired with beauty nutrients. This benefit is complementary and may be most noticeable when combined with consistent intake and good overall nutrition.
Antioxidant Support
Includes selenium and zinc, which are commonly used to support normal antioxidant-related nutrient functions in the body. Nettle leaf extract also contributes plant-derived compounds that may complement a general wellness routine. This is a peripheral benefit compared with the formula’s primary beauty positioning.
