Why use food supplements for hair and nails?
The quality of your hair and nails depends partly on your nutritional balance, particularly your intake of micronutrients such as zinc, biotin, and selenium, which contribute to the maintenance of normal hair.
However, it can sometimes be difficult to meet these needs through diet alone. This is the case if:
- You have an unbalanced or unvaried diet;
- You follow a vegetarian or vegan diet with limited zinc;
- You are going through a period of transition, such as a change of season.
A hair and nail supplement regimen helps you complete your intake. By supporting hair fibers and nails from within, it helps improve hair quality, limit hair loss, and strengthen nails.
The benefits of hair and nail food supplements
Our collection of food supplements targets three objectives to maintain the beauty of your hair and nails.
- ✓ Prevent and limit hair loss
Hair loss is a common, often temporary phenomenon that can result from insufficient nutrient intake. Several studies also associate low zinc levels with more significant hair loss (2)(3). Our Hair Formula provides zinc, biotin, and selenium, alongside KerPep® keratin and sulfur amino acids, to support hair fibers and help reduce hair loss. However, significant or persistent hair loss should be medically monitored.
- ✓ Strengthen hair fibers and promote growth
Hair growth depends on the vitality of the hair bulb, which itself depends on the available micronutrients. Keratin and sulfur amino acids like L-cystine contribute to the hair's structure, while zinc and biotin contribute to the maintenance of normal hair. By supporting these intakes, a targeted regimen like our Hair Formula strengthens hair fibers and promotes growth.
- ✓ Support nail resistance
Brittle or soft nails can indicate insufficient nutritional intake, particularly of zinc, which contributes to the maintenance of normal nails. Our Zinc Bisglycinate, offered in a well-absorbed form, is included in the selection alongside Hyaluronic Acid.
Which supplements should you prioritize for healthy hair and nails?
Keratin
Keratin is the protein that forms the majority of hair. For it to be well absorbed, it is better to choose hydrolyzed keratin with a low molecular weight, which helps support the hair fiber's structure. This is the case with bioactive KerPep® keratin, extracted from 100% French sheep's wool and concentrated at over 90% in bioactive peptides, making it one of the most absorbable on the market.
Biotin (vitamin B8), for normal hair
Biotin, or vitamin B8, is one of the reference active ingredients for hair. It contributes to the maintenance of normal hair by notably participating in the metabolism of amino acids, the very constituents of keratin. Our Hair Formula provides 100 µg per daily dose, or 200% of the reference daily intake.
Zinc and vitamin B6
Zinc is a key mineral for hair and nails: it contributes to the maintenance of normal hair and nails, as well as to normal protein synthesis. It is one of the few active ingredients that acts on both hair and nails. We exclusively use zinc bisglycinate, a chelated form that is well tolerated and known for its good absorption.
Vitamin B6 contributes to the normal metabolism of proteins, including keratin, the main protein of hair and nails. It also participates in the normal synthesis of cysteine, one of the amino acid constituents of this keratin.
Sulfur amino acids
Keratin is rich in sulfur amino acids, primarily L-cystine and L-methionine. As true building blocks of hair, they provide the hair fiber with its raw material and support its structure. L-cystine notably participates in disulfide bridges, bonds that bring keratin chains closer together and ensure the cohesion, strength, and resistance of the hair fiber.
Plants and minerals
Beyond vitamins and amino acids, certain plants and minerals are traditionally associated with the beauty of hair and nails.
On the plant side, we find rocket, naturally rich in vitamins K and B9, used in the Hair Formula to support growth and nourish the hair fiber. On the mineral side, zinc and selenium both contribute to the maintenance of normal hair and nails. These are two essential active ingredients for a hair and nail regimen.
