Hair, nail, and skin gummies have seen significant growth in France in recent years. In the form of fruit-flavored chewable gummies, these dietary supplements promise to strengthen hair and accelerate its growth. But is this format truly effective, or is it primarily a marketing ploy?
What is a hair gummy?
A hair gummy is a dietary supplement in the form of chewable gum, generally enriched with B vitamins, trace elements, and sometimes plant or fruit extracts. From a practical standpoint, this format offers real advantages: it doesn't require water, can be easily taken anywhere, and avoids the sometimes unpleasant sensation of swallowing a capsule.
In terms of effectiveness, however, the gummy format does not in itself provide any additional benefit compared to a capsule or a tablet: it is the composition and dosage of the active ingredients that determine the potential interest of the product, not the galenic form.
Which ingredients are actually beneficial for hair?
Several nutrients found in hair gummies have varying levels of evidence regarding their role in hair health.
B vitamins are among the most frequently mentioned. Biotin (vitamin B8) has a health claim validated by the EFSA regarding the maintenance of normal hair, but this claim applies only in the context of a proven deficiency: in a person who is not deficient, the benefit of additional biotin supplementation remains debated. Vitamin B6 is involved in protein metabolism, including keratin, while vitamins B9 and B12 play a role in cell renewal and tissue oxygenation, including that of the scalp.
Vitamin E is an antioxidant that can help protect cells from oxidative stress, a mechanism involved in cellular aging in general. Zinc and selenium are two trace elements whose deficiencies are associated with weakened hair and nails, which explains their frequent presence in these formulas.
Certain antioxidant-rich fruit extracts, such as blueberry, are sometimes added for their interesting nutritional profile, although specific studies on their isolated effect on hair are not available to date.
Are hair gummies effective for everyone?
The effectiveness of a hair supplement largely depends on the individual. In someone with a known deficiency in biotin, iron, zinc, or B vitamins, appropriate supplementation can help improve hair condition, in addition to a balanced diet. However, in someone whose diet already meets these needs, the effect of additional supplementation is generally more limited.
It's also important to remember that no dietary supplement, regardless of its form, can make hair grow faster than the natural biology of the hair growth cycle allows. To better understand this cycle and the factors that truly influence growth, our article on tips for promoting hair growth details the most well-documented approaches.
How to choose the right hair gummy?
To assess the suitability of a hair gummy, several criteria should be examined. The dosage of the main active ingredients per daily serving allows verification of whether it corresponds to the reference intake. The presence or absence of added sugars influences the overall nutritional profile of the product, as does the origin of the gelling agent (vegetable pectin or animal gelatin) for those following a vegetarian or vegan diet.
It's also important to remember that a dietary supplement should never replace a varied and balanced diet, which remains the foundation of healthy hair, nails, and skin. To care for your hair daily, a healthy diet should be combined with appropriate external treatments.
Precautions for use
Hair gummies are generally not recommended for children under 16. Pregnant or breastfeeding women, people taking medication, or those with allergies should consult a doctor before taking any supplements. It is also recommended not to exceed the daily doses indicated by the manufacturer and not to combine multiple sources of supplements containing the same vitamins or minerals without professional advice, as some nutrients (such as zinc or vitamin A) can have adverse effects if taken in excess over a prolonged period.
Information on reference intakes is available on the Anses website.
Frequently asked questions about hair gummies
How long does it take to see results with hair gummies?
Because the hair growth cycle is slow, it is generally recommended to observe a treatment for at least three months before any effect can be assessed, to allow time for the new hairs grown during the treatment to become visible.
Are hair gummies more effective than regular capsules?
No, effectiveness depends on the dosage and quality of the active ingredients, not the dosage form. Gummies primarily offer an advantage in terms of convenience and ease of use.
Can you take hair gummies without any particular deficiency?
This remains possible in the context of occasional consumption, but the effect will generally be more limited in a person whose diet already covers the needs for the vitamins and minerals concerned.
