Hair Boost Key Ingredients
Strong, healthy hair starts from within. Hair Boost combines science and nature to care for the hair follicle through all its phases.

AnaGain™ Nu (Pea Shoot Extract)
Plant extract clinically evaluated for oral supplementation. In studies of adults with mild–moderate hair loss, less hair loss and improved perceived density were observed after weeks of use. It is positioned as support for the follicular microenvironment and the balance of the anagen–telogen cycle.

Cynatine® (Soluble Hydrolyzed Keratin)
Soluble keratin with high affinity for hair fiber and clinical evidence in hair parameters. In trials with 500 mg/day, more hair was observed in anagen, less in telogen, and improved shine/appearance.
In Hair Boost, it is included in an adjusted dose and in synergy with other nutrients, positioned as an adjuvant for the structure and quality of the fiber.

Reduces hair loss
Patented extract with clinical evidence in stressful contexts: in adult trials, modulation of stress markers (cortisol) and improvements in well-being and sleep quality were observed with continued use. In Hair Boost, it is communicated as systemic support when stress is a factor in hair balance.

AstaReal® (Astaxanthin)
Carotenoid with antioxidant activity. In skin studies with 2–6 mg/day for 6–12 weeks, improvements in elasticity, hydration, and TEWL were observed. In Hair Boost, its role is to provide antioxidant support to the follicle's microenvironment as part of an "inside-out" routine.
MSM (Methylsulfonylmethane)
A compound that provides bioavailable sulfur, involved in keratinization (keratin disulfide bridges). In Hair Boost, it is positioned as a structural coadjuvant for the hair fiber, in synergy with L-cystine and vitamin B6.
Bamboo Extract
Provides silicon, a trace element linked to collagen/keratin architecture processes. Its function in the formula is to support the hair fiber matrix as part of an "inside-out" strategy, synergizing with sulfur cofactors and B6.
Minerals: Zinc, Selenium, and Copper
Zinc (citrate), Selenium (yeast-enriched), and Copper (gluconate)
Minerals in highly bioavailable forms that provide benefits with EU-authorized health claims:
Zinc: contributes to the maintenance of normal hair and skin, to normal protein synthesis, and to the protection of cells from oxidative damage.
Selenium: contributes to the maintenance of normal hair and to the protection of cells from oxidative damage.
Copper: contributes to normal hair pigmentation, to the maintenance of normal connective tissues, and to the protection of cells from oxidative damage.
Vitamins: B6, C, and E
Vitamin C: contributes to normal collagen formation and to the protection of cells from oxidative damage.
In hair, collagen is part of the scalp's architecture; good collagen support helps maintain the structural environment where hair grows. Its antioxidant function helps protect against external factors (UV, pollution).
Vitamin E: contributes to the protection of cells from oxidative damage.
In hair, it acts as a lipophilic antioxidant in cell membranes, useful for the oxidative balance of the scalp and hair fiber in "inside-out" routines.
Vitamin B6: contributes to the normal synthesis of cysteine and to the regulation of hormonal activity.
In hair, cysteine is key for keratinization (disulfide bonds). B6 works with L-cystine, MSM, and zinc in the structural support of the fiber. Its role in hormonal regulation is especially relevant during perimenopause/menopause.

High tolerance, no sugar or flavorings
Hair Boost is a hair supplement without sugar or sweeteners, gluten or lactose , suitable for demanding lifestyles.
Its vegetarian capsule presentation allows for better digestion and a clean experience. The capsules can be opened and the powder added to your favorite beverage.

Why without biotin?
Formula without biotin or megadoses
This decision responds to the growing concern about:
- The lack of evidence regarding its effectiveness in people without a deficiency.
- Its association with skin side effects, such as acne in sensitive skin.
- The massive presence in standard supplements, which leads to greatly exceeding the NRVs (nutrient reference values) and duplications if consumed from other sources (multivitamins, fortified foods, etc.).
This trend of removing biotin from supplements today is being supported by experts in dermatology and gynecology.
Frequently Asked Questions
Hair Boost differs from other hair supplements because it does not contain biotin in high doses, thus avoiding potential acne problems, and because it respects Nutrient Reference Values (NRVs), without resorting to megadoses, given that a food supplement should not replace a varied and balanced diet or a healthy lifestyle.
Its multifactorial formula is designed to address all factors that can affect hair growth, such as nutrition, stress, oxidation, and hormonal balance.
In addition, it offers high tolerance, with no added flavorings, sugars, or sweeteners, and combines 13 active ingredients in highly bioavailable forms, including 4 patented ingredients with scientific studies that support their benefits for hair health.
Hair Boost is formulated to be taken continuously, thanks to its balanced composition and lack of mega-doses. A minimum use of 3 to 6 months is recommended for optimal results, with the option to maintain it over time or take 1-month breaks if preferred.
Yes, Hair Boost is compatible with topical hair treatments such as specific shampoos, scalp exfoliants, lotions, or even medical treatments like minoxidil or PRP. It works from within as a supplement to enhance results.
Yes, some of the active ingredients such as hydrolyzed keratin, zinc, and silicon also contribute to improving nail strength and skin quality, although Hair Boost's primary focus is hair care.
Hair health is a gradual biological process, so response times may vary depending on the initial condition of the hair and the consistency of taking the supplement. According to our internal test data, the effects of Hair Boost are usually observed as follows:
Month 1-3: Less hair loss, a more relaxed scalp sensation, and an overall improvement in its condition are observed.
Month 4-6: Faster hair growth, less hair breakage are experienced, and new hairs may begin to appear, especially in the frontal area.
Month 7 onwards: Hair tends to be stronger, with more volume and greater density.
The key is consistency: every capsule counts in the hair transformation process.
If pregnant or breastfeeding, a medical professional should be consulted before starting any supplementation.
Modesta Cassinello's Hair Boost is formulated to care for your hair from the inside out. Its innovative formula acts on the main causes of hair loss and weakening: hormonal changes, poor nutrition, aging, and stress. That's why it includes Ashwagandha, a clinically proven adaptogen to reduce stress and cortisol levels, promote mental well-being, and improve sleep quality.
Keep the container in a cool place, away from light. Once opened, close the container tightly after use.
You can take it as soon as you remember. However, if it's almost time for your next dose, skip the missed dose and continue with your regular schedule. It's not a problem to miss a day, or to take it one day at breakfast and another at lunch or dinner.
If you notice excessive or prolonged hair loss, brittle, dull hair, or problems such as an altered scalp, it could be a sign that your hair needs nutritional reinforcement. It is a magnificent dietary supplement during seasonal hair loss to promote new hair growth and improve hair quality.
ASHWAGANDHA
In healthy adults, standardized ashwagandha extracts have shown good tolerability in clinical studies. A 12-month prospective study published in Phytotherapy Research monitored hepatic, renal, and thyroid parameters and observed no clinically relevant changes in major safety markers.
Cases of liver damage have rarely been reported in people taking supplements marketed as ashwagandha; in some cases, the influence of product variability or multi-ingredient formulas cannot be ruled out. As a precaution, if jaundice, dark urine, severe itching, persistent nausea, or abdominal pain appears, discontinue use and consult a healthcare professional.
"Ashwagandha" does not always mean the same thing: the plant part, extract type, standardization, and quality controls can vary. In Hair Boost, we use Sensoril®, a root extract standardized to 10% withanolides, at a dose of 100 mg/day, within a multifactorial formula aimed at hair wellness. Choosing standardized and traceable ingredients helps ensure consistency and confidence in use.
As a precaution, avoid ashwagandha if you have liver disease. Consult your doctor before using if you are pregnant or breastfeeding, if you are a minor, if you are being monitored for thyroid issues, or if you are taking medication with potential interactions (e.g., sedatives/anxiolytics). If you have any doubts or are undergoing medical treatment, it is best to get personalized advice from a healthcare professional.
