Premature greying, grey roots, stress at the very first silver strands… What if a patented natural active ingredient could turn the tide? A recent scientific study points to a promising solution capable of naturally stimulating melanin, the key pigment for preserving your hair colour. Discover why this revolutionary supplement is already causing a stir.

An inevitable part of the ageing process, the appearance of grey hair can be a concern for anyone wishing to maintain a youthful, vibrant head of hair. Genetic factors, emotional stress, cellular oxidation… the causes of greying are many, but they all share one key factor: a gradual decline in melanin, the natural pigment responsible for hair colour. But today, a major scientific breakthrough is changing the game, thanks to an innovative ingredient derived from the wool of black sheep: the patented melanin supplement known as Melaline®/Melatine®. Its clinically proven effectiveness could well spell the end of premature greying.

Why does hair turn grey?

When melanin – a natural pigment produced by cells called melanocytes – becomes scarce, the hair gradually loses its original colour. Several studies, including one recently published in a renowned international scientific journal, clearly detail the mechanisms involved: the activity of the enzyme tyrosinase decreases, melanocytes gradually disappear, and melanin struggles to reach the hair shaft. The result: hair inevitably turns grey.

Melaline® / Melatine®, the natural solution validated by clinical studies

Fortunately, recent research has highlighted a promising innovation: the patented active ingredient Melaline® / Melatine®, naturally extracted from the wool of black sheep reared in France. This dietary supplement, which is fully bioavailable thanks to an exclusive enzymatic process, has been scientifically proven to stimulate melanogenesis – that is, the body’s natural production of melanin. It provides the skin and hair follicles with the essential nutrients and precursors needed to promote natural melanin production.

Rigorous clinical studies conducted on 32 people over a period of 4 months show surprising results*:

  • Visible repigmentation of hair that was initially salt-and-pepper: after just 2 months’ use, a gradual repigmentation of emerging white hairs was observed, and this effect intensified when the treatment was continued for up to 4 months.

  • Noticeable strengthening of the hair with reduced hair loss. 90 per cent of testers reported this.

  • High satisfaction (95 per cent of testers): they noted an overall improvement in the colour and quality of their hair.
