What makes hair grow?

Effectively treating hair loss requires more than just slowing it down. To restore thick, healthy hair, it’s essential to reactivate growth by stimulating the hair follicles.

Two complementary and inseparable actions are at the heart of an effective anti-hair loss strategy:

• Slow down hair loss by targeting its causes (stress, deficiencies, hormonal imbalances, etc.)
• Stimulate the growth of new, stronger, and better anchored hair.

It is this dual action—prevention and stimulation—that gradually restores the density and quality of the hair. Targeted hair care, proven active ingredients, appropriate techniques, dietary supplements… Everything counts in rebuilding the hair cycle.
 

What factors influence hair growth?

Hair growth is not determined by genetics alone. Many internal and external factors can influence its life cycle and overall health.

Among the most common are:

• Diet: iron, zinc, vitamin B, or protein deficiencies can slow down growth.
• Stress and hormonal imbalances: during periods of intense or prolonged stress, the body produces more cortisol, which can disrupt the hair cycle and lead to temporary shedding. Similarly, certain hormonal disorders, such as thyroid imbalance, can indirectly affect hair health and contribute to more diffuse hair loss.
• Age: with age, the hair cycle naturally slows down.
• Hair care: harsh products, excessive heat and frequent manipulation weaken the hair fiber and irritate the scalp.
• Lifestyle: smoking, pollution and lack of sleep also affect hair health.

Taking care of your hair with an effective routine tailored to your scalp is the best way to support healthy, long-lasting growth.
 

Active ingredients used by René Furterer to promote hair regrowth

Today, natural and effective solutions exist to promote hair growth.

René Furterer uses seven natural ingredients to develop its hair loss treatments and dietary supplements. The brand offers personalized solutions tailored to each individual's needs and specific conditions.

The effectiveness of these natural active ingredients in promoting hair growth has been widely proven and verified by users.
 

Natural mangosteen extract

Mangosteen (Garcinia Mangostana), sourced from an ethical Fair For Life supply chain and nicknamed the “fruit of the gods” is a tropical “superfruit” native to Southeast Asia. Its purple rind is known in traditional Asian medicine for its exceptional antioxidant, anti-inflammatory, and regenerative properties. 

It is in this shell, known as the pericarp, that we find a natural source of active ingredients called xanthones, including alpha mangosteen. Pierre Fabre Laboratories manufacture mangosteen extract in Gaillac, in the Tarn region of France, which is the key ingredient in the effectiveness of the Triphasic Progressive formula.

Hydrolysed curbicia extract

Curbicia is a valuable ally in promoting hair regrowth, especially in cases of progressive hair loss and on scalps suffocated by hyperseborrhea, i.e., excessive sebum production. This imbalance makes the scalp oilier, disrupts oxygenation, and can hinder hair growth by clogging the hair follicles. 

Curbicia is a 100% natural extract obtained by hydrolyzing pumpkin seeds (cucurbita pepo). This plant-based active ingredient was selected by René Furterer for its regulating action on oily scalps.

Thanks to its sebum-reducing properties, curbicia extract helps rebalance sebum production without irritating the skin. It deeply purifies the scalp, limits hair follicle blockage and creates an environment conducive to healthy hair growth.

Hair grows faster, stronger, and healthier, and the hair fiber is more resilient.

ATP: an innovative active ingredient

ATP, or adenosine triphosphate, is an active ingredient naturally produced by the body. It is an essential source of energy, as it is the only “fuel” that cells can use directly.

René Furterer research has uncovered the incredible properties of ATP on follicular papilla cells.

It helps quickly restart hair growth:

1. In progressive hair loss by acting as an early energy signal.
2. In reactive hair loss by acting on the induction of the anagen phase.

Highly effective for all types of hair loss, this active ingredient* is therefore included in both René Furterer anti-hair loss treatments.

Debunking common myths about hair growth

Hair grows faster if you cut it regularly

Many people believe that trimming the ends stimulates hair growth. In reality, cutting has no direct effect on the speed of growth, which depends on the activity of the hair follicle, located under the skin. However, removing split or damaged ends helps prevent breakage. When hair is very fragile, it breaks at the ends, giving the impression that it is no longer growing. Regular trims therefore help to maintain stronger, healthier, and visibly longer hair over time.

Washing your hair too often slows down growth

Washing your hair regularly does not prevent it from growing. However, using a product that is too harsh or shampooing too often can weaken the scalp and hair fiber. Choose products suited to your hair type to keep it healthy and create the best environment for growth.

Do certain foods really make hair grow faster?

It's a very persistent idea: eating eggs, brewer's yeast or drinking nettle juice will miraculously make your hair grow back. In reality, no food has the power to trigger hair growth on its own. However, a balanced diet, rich in protein, iron, zinc, B vitamins, and essential fatty acids, is important for supporting the hair's life cycle.

Rather than relying on a “superfood,” focus on a varied and balanced diet, and if you have any deficiencies, do not hesitate to consult a professional or take a targeted supplement, especially during periods of stress or fatigue.

Hair growth is a complex biological process shaped by internal rhythms, lifestyle, and care rituals. By understanding the hair cycle and choosing treatments with proven natural ingredients, you can restore strength, density, and vitality — rooted in science, guided by nature.
