Your hair loss is accelerating, your hair fiber is weakening: it may be due to a zinc deficiency. Although this essential nutrient for skin and hair beauty is found in a balanced diet (seafood, seaweed, red meat, whole grains), its intake is often insufficient, and hair becomes more thin, dry, and brittle. With Nooance-Paris, discover all the benefits of zinc and how to integrate it into your daily life through food supplements to regain shiny and healthy hair.

Key takeaways
- Key role: Zinc orchestrates keratin synthesis, ensuring hair growth and density.
- Symptoms of deficiency: Thin, dull, brittle hair, and sudden diffuse hair loss (telogen effluvium).
- Optimal supplementation: Choose Zinc Bisglycinate for maximum absorption by the intestines.
- Protocol: A minimum 3-month course is essential to support the complete hair follicle cycle (anagen phase).
How does zinc affect the hair fiber?
The pillar of keratin synthesis
Zinc is directly involved in the synthesis of keratin, the main protein that makes up hair. Rich in sulfur amino acids, keratin requires a suitable enzymatic environment: zinc acts here as a cofactor for many enzymes involved in protein synthesis, ensuring a more resistant, better structured hair fiber that is less prone to breakage.
Cell division and anagen phase
It is during the anagen phase (hair growth phase) that cellular activity is most intense. Zinc intervenes at the hair bulb to promote cellular regeneration and the renewal of hair follicles. It is therefore an essential trace element for good hair growth, regular growth and visibly denser hair.
Sebum regulation and scalp health
Zinc also contributes to scalp balance by regulating sebum production. It notably exerts an inhibitory action on 5-alpha-reductase, an enzyme involved in the conversion of testosterone into DHT (dihydrotestosterone), known to weaken hair follicles in certain types of alopecia.
Hair loss: signs of zinc deficiency
Among the causes of hair loss, zinc deficiency is common but often underestimated. It can gradually weaken hair structure and disrupt the growth cycle.
Thinning hair shaft and loss of shine
Lack of zinc impairs keratin production, an essential protein for beautiful hair. This leads to thinner, dull, and brittle hair, often associated with a loss of hair density and radiance.
Reactive hair loss (telogen effluvium): the alarm signal
When the deficiency is too significant, hair prematurely enters the telogen phase (hair shedding phase). This results in a sudden, diffuse, and "by the handful" hair loss.
Expert criteria: which food supplement to choose for real effectiveness?
Nooance-Paris revolutionizes nutricosmetics and food supplements with a global solution, designed to act on all spheres of beauty (skin, hair, and nails) thanks to powerful and targeted active ingredients, validated by clinical studies.
Zinc bisglycinate, highly bioavailable
In its bisglycinate form, zinc has better bioavailability, making it more absorbable by the body. It benefits from better digestive tolerance than zinc gluconate, ensuring enhanced efficacy on keratin synthesis and support for the hair cycle.
Cofactors: synergy with vitamin B6 and magnesium
For visible results, it is essential to prioritize a zinc treatment combined with key cofactors (vitamins, amino acids) to maximize its action on hair growth and density.
The Nooance Paris Beauty Food Supplement combines highly absorbable zinc bisglycinate with vitamins and minerals that directly play a role in hair growth:
- Vitamin B5
- Biotin (Vitamin B8)
- Antioxidants: vitamins C and E
- Marine collagen 2,000 DA

The double action of Zinc and red light for healthy hair
Nooance-Paris combines the effectiveness of essential nutrients like zinc with the action of red LED light to stimulate hair fibers from within and promote healthy and sustainable growth.
The mechanism of photobiomodulation
Among Beauty Tech devices, the LED hair helmet is an innovative device designed to support hair growth thanks to powerful and non-invasive technology. The red LED light emitted by the helmet stimulates ATP (adenosine triphosphate), a molecule that directly contributes to maintaining healthy hair follicles. Discover our dedicated article to better understand red light therapy for hair.
The In & Out approach: The synergy of Nutrition (Zinc) and Stimulation (LED)
By combining red light and a zinc course, an optimal environment for hair growth is created. The light from the professional LED hair helmet acts as a local activator: it dilates the micro-blood vessels of the scalp. This increased blood flow then massively delivers zinc (from your Beauty food supplement) directly to the heart of the hair bulb. Thus, the LED restarts the production factory (the follicle), while zinc provides the essential raw material for producing a thick and resistant hair fiber.
The Nooance Laser and LED Hair Helmet is currently the only dual-technology laser and LED helmet with proven wavelengths and a pulsed mode worthy of aesthetic medicine practices.

Usage tips: dosage and optimal routine
When to take your zinc supplement?
In the morning, on an empty stomach, with a large glass of water, or between meals, for optimal intestinal absorption.
Duration of the treatment for visible results
A 3-month course is recommended to obtain results on hair growth. Indeed, the hair cycle extends over several weeks: growth (anagen phase), transition (catagen phase), and shedding (telogen phase). A regular and progressive supplementation therefore makes it possible to cover a complete cycle and obtain more lasting results.
Semantic Glossary
- 5-alpha-reductase
- An enzyme that converts testosterone into DHT, a hormone responsible for hair miniaturization and loss in androgenetic alopecia. Zinc helps to inhibit it.
- Telogen effluvium
- Diffuse and sudden hair loss caused by physical or nutritional stress (such as severe zinc deficiency), prematurely pushing hair into the shedding phase.
- Zinc Bisglycinate
- A chelated form of zinc (bound to an amino acid, glycine) recognized by the intestine as a protein, ensuring maximum absorption without digestive problems.
FAQ Zinc and hair: the keys to effective supplementation
Does zinc make hair grow back?
Zinc alone does not make hair grow back, but it plays a key role in restarting the hair growth cycle. In case of deficiency, the hair cycle is disrupted: hair prematurely enters the shedding phase (telogen phase). By restoring sufficient intake, zinc helps to reactivate the anagen phase (growth phase), by supporting cell division at the hair bulb and keratin synthesis.
How long does it take to see the effects of zinc on hair?
The first results generally appear after 6 to 8 weeks (slower shedding, more resistant hair), while visible regrowth often requires 2 to 3 months of treatment because hair follicles must transition from their resting phase to an active growth phase.
What are the side effects of excess zinc?
Excessive zinc consumption can be counterproductive. An excessively high intake of zinc can interfere with copper absorption, leading to a secondary copper deficiency, which itself can cause hair loss and other undesirable effects.
Can zinc and iron be combined in a treatment?
It is advisable to avoid simultaneous iron and zinc supplementation: space out the doses by approximately 2 to 3 hours to promote better intestinal absorption of each micronutrient without them competing with each other.
