Publié le 03-06-2025 et mis à jour le 09-06-2025
Months go by and you see your fine hair thinning more and more. Stress, pollution, hormonal upheavals, a diet poor in essential nutrients are all contributing factors.
External aggression factors like those mentioned or bad care habits affect hair in a completely different way compared to a cause that would be hormonal.
Indeed, it is possible to have fine hair because it is devitalized, but also hair that grows less and is of poorer quality following pregnancy, menopause, or thyroid dysfunction that have affected the hormones responsible for the proper growth of your hair. As a result, you experience hair mass loss, you have tried everything, and you no longer know where to turn.
This is where dietary supplements for fine hair come into play; you need to act from within!
Summary
I. Understanding the causes of fine hair
Genetic and hormonal factors
Fine hair often originates from genetics, with each individual inheriting a hair structure unique to their family heritage.
However, hormonal variations are a determining factor in the evolution of hair density and quality.
Imbalances related to pregnancy, menopause, polycystic ovary syndrome (PCOS), or periods of intense stress can disrupt the hair cycle, shorten the growth phase, and prolong the shedding phase.
This phenomenon results in volume loss, gradual thinning, and weakening of the hair fiber.
Seasonal change
Seasonal change represents a pivotal period for hair health, especially for people with fine hair.
In autumn as in spring, variations in temperature, humidity, and light, combined with accumulated fatigue or stress, can disrupt the hair cycle.
This natural transition is often accompanied by temporary hair loss and fiber thinning. To preserve the density and vitality of fine hair during these sensitive phases, targeted nutritional support is essential.
Dietary supplements based on keratin, B vitamins, selenium, and plant extracts promote fiber strength and stimulate growth, thus limiting the negative impact of seasonal changes on the hair.
Diet, lifestyle, and their impact on hair health
An unbalanced diet, poor in essential micronutrients, directly affects hair vitality.
Deficiencies in B vitamins, biotin, iron, vitamin D3, or sulfur-containing amino acids limit the production of keratin, a fundamental element of the hair fiber.
Modern lifestyle, often marked by stress, fatigue, and pollution, worsens these nutritional deficiencies and weakens the hair.
Insufficient intake of essential nutrients results in finer, duller, and more brittle hair.
External aggressions: stress, pollution, and unsuitable care
Hair is exposed daily to external aggressions such as pollution, fine particles, oxidative stress, and the use of unsuitable hair products.
Shampoos, conditioners, and masks containing sulfates, silicones, or parabens can clog the scalp, suffocate hair bulbs, and accelerate fiber thinning.
Brushing wet hair, frequent use of heat styling tools, or excessive washing frequency also contribute to fragility and loss of hair density.

II. Why choose dietary supplements for fine hair?
Essential natural actives to strengthen hair
To thicken and strengthen fine hair, the supply of targeted natural actives via a hair dietary supplement is essential. The best formulas include pure keratin, B vitamins (including biotin), vitamin C, vitamin D3, selenium, marine magnesium, iron, as well as plant extracts such as horse chestnut, red vine, or milk thistle. These ingredients work synergistically to strengthen the fiber, stimulate scalp microcirculation, rebalance hormonal environment, and support hair growth.
Bioavailability: a key criterion for optimal effectiveness
The effectiveness of a dietary supplement depends on the bioavailability of its active ingredients, that is, their ability to be absorbed and used by the body. Favoring ultra-sourced, highly bioavailable ingredients from Green Tech guarantees deep action and visible results on hair density and quality. French manufacturing, respecting strict standards, ensures traceability and excellence of each formula.
How to identify the best dietary supplements for fine hair?
The best dietary supplement for fine hair stands out by a composition rich in patented active ingredients, a comprehensive action on the internal and external causes of hair thinning, and clinically proven results. It must also be formulated without compromise on naturalness, ethics, and ingredient traceability. Superior quality hair capsules are made from premium actives, selected for their efficacy and safety, and manufactured in France to ensure perfect quality process control.
- Presence of pure and patented keratin (Cynatine® HNS2)
- Combination of vitamins, minerals, and plant extracts
- Results demonstrated by clinical study
- Clean formulation, without controversial additives
III. Which supplement to take to thicken fine hair?
To grow vigorously and thicken, fine hair needs sulfur amino acids, minerals, and vitamins.
A deficiency in biotin (B vitamin), vitamin E, and other nutrients can cause hair loss and deterioration.
- Vitamin E is an antioxidant that protects the scalp from free radicals. It also helps protect the scalp's natural oils from ultraviolet rays.
- Vitamin C : It stimulates collagen production which helps strengthen the connective tissues of your scalp.
Nowadays, foods travel around the world before reaching our plate, cultivation methods differ (greenhouse farming), and climate change leads to soil leaching...
Unfortunately, once in our mouth, our foods contain very little in terms of micronutrients!
To help the bulb effectively weave its hair fiber, it needs to be supplied with the missing elements.
Here is a list of dietary supplements you should consider taking if you want to improve your hair health:
- Keratin Absolute: keratin is the main component of hair. It acts like cement between the hair and its bulb. The anti-hair loss effect is ensured and your hair regains its thickness.
- Growth Complex: Our Growth Complex formula contains all the ingredients necessary for keratin production and thus for beautiful coated hair: amino acids, B vitamins, and trace elements.
Find the two combined formulas in the Hair Nutrition Duo. Together, they form the perfect supplementation to regain volume and mass, fill in your hair scales, and restore thickness.
- The Pro-Collagen Hair 360°: This active concentrate targets the hair fiber as a whole. Thanks to type I marine collagen, vitamin C, and antioxidants, it supports the hair structure, improves its resistance, and restores suppleness to your hair. A true youth treatment for fragile, thinning, or brittle hair. 💚
- The Hair Mass Program: A complete treatment in three expert formulas for a 360° action: stimulate microcirculation in the scalp, nourish the hair bulb, and boost keratin production. Ideal in case of density loss, thinning hair, or hormonal hair loss. The perfect combo to regain dense, strong, and radiant hair. ✨
IV. The hair mass program from D-LAB NUTRICOSMETICS

Specifically designed to thicken the fiber, combat hair loss related to hormonal imbalance, and restore density and vitality to the hair, this program combines 20 highly bioavailable natural actives.
Among them, Cynatine® HNS2, a pure patented keratin, myo-inositol, marine magnesium, coenzyme Q10, selenium, vitamin D3, plant extracts (horse chestnut, milk thistle, red vine), and chlorella powder.
Each ingredient targets a specific lever: hormonal regulation, hair density, and microcirculation stimulation.

The concrete benefits of the hair mass program
The results of the Hair Mass Program are demonstrated by a clinical study: 4 times less hair loss, 88% of users notice an improvement in hair quality, 88% report strengthened hair, 94% are satisfied with the volume of their hair, and 91% are overall satisfied. This treatment addresses all issues related to fine hair, whether it is diffuse density loss, hormonal hair loss, or preventive care. It strengthens the fiber, stimulates growth, adds volume, and prevents thinning in the long term.
- Significant reduction in hair loss
- Visibly thicker and stronger hair
- Improvement in hair density and volume
- Visible results from 3 months of treatment
A holistic approach for thicker and healthier hair
The hair mass program combines three complementary formulas:
- The Balance Activator, a formula that rebalances the entire neuro-hormonal system thanks to its supply of active precursors of serotonin, the well-being hormone, and melatonin, the sleep hormone. By feeling good and sleeping well, you wake up with less stress and perfectly regulated hormone levels. After 1 month of treatment, you already begin to feel very beneficial effects.
- Second step, you need to strengthen the hair from within and fix it as much as possible to its bulb to maintain a significant mass and volume effect. This is the work of keratin. Our keratin is natural and comes from black sheep wool. Thanks to a biotechnological extraction process, we can extract the Cynatine molecule from our keratin, which has been the subject of a clinical study proving its effectiveness.
- Finally, it is just as important to act on the deep cleansing of the scalp, blood circulation, and toxin elimination. An aerated scalp, hair not thinned. Our Microcirculation Detox acts on all these internal levers to give a real fresh boost to our hair!
To act 360° on the issue, these three formulas must work in synergy. D-LAB has therefore created the Hair Mass Program, which contains these three formulas, to be taken together every day for 3 months, for optimal results.
This comprehensive approach regulates hormonal balance, supports scalp microcirculation, and strengthens the very structure of the hair.
The treatment adapts to both temporary hair loss and preventive needs. The ingredients are ethically and sustainably sourced, from French supply chains and controlled according to strict standards to guarantee the excellence and naturalness of each formula.
- Action on hormonal and nervous regulation
- Strengthening of the hair fiber with patented keratin
- Stimulation of microcirculation and detoxification of the scalp
- Prevention and treatment of hormonal hair loss
V. Maximize results with an adapted routine
Tips to optimize the effect of dietary supplements
To enhance the effect of a dietary supplement for fine hair, it is recommended to follow a treatment for at least 3 months, respecting the recommended dosage (2 capsules of each formula per day, except 1 tablet for Absolu de Kératine), and to split the intake between breakfast and lunch while maintaining good hydration. A balanced diet, rich in organic fruits and vegetables, combined with gentle cooking (steaming), promotes the absorption of essential micronutrients. It is also relevant to combine a Liver Detox once or twice a year to purify the body and support hair vitality.
- Respect the recommended treatment duration
- Maintain a varied and balanced diet
- Stay well hydrated daily
- Combine with liver detoxification to optimize results
Complementary hair care to strengthen and thicken hair
In addition to the treatment, it is recommended to adopt a hair care routine that respects the fiber: favor natural treatments, such as vegetable oil baths (castor oil for growth and strengthening, coconut for softness, argan for nutrition, aloe vera for hydration), use shampoos free of silicones, sulfates, or parabens, space out washes to stimulate the natural regulation of sebum, and opt for a comb rather than a brush to limit breakage. Using a microfiber towel for drying and avoiding heat styling tools daily also helps preserve hair density. A suitable diet, good stress management, and a balanced lifestyle are also valuable allies to strengthen hair over time.
- Natural and gentle care for the scalp
- Space out shampoos and avoid harsh products
- Limit the use of heat styling tools
- Promote a diet rich in micronutrients
