What Is Activance Rhodanide?
Activance is the latest advancement in hair cosmeceuticals to revive thinning, damaged and lifeless hair, for both men and women.

Activance contains rhodanide a natural and vital molecule found in all living cells (plants, animals and human life) including human hair.
In 1993 rhodanide was classified a vitaminoid (vitamin like substance).
Similar to vitamins rhodanide plays an essential and indispensable role in cellular activities and acts as a natural antioxidant / purifying agent.
Reduced supply or increased demand of rhodanide can lead to symptoms of deficiency.
Research studies have shown that thinning, dry, damaged and coloured hair has significantly lower level of rhodanide than healthy, shiny hair.
Boosting rhodanide levels revives hair and lengthens the growing cycle, immediately improving strength, shine and growth of each hair.

It's the quick and easy-to-use solution that will deliver visible results immediately.
Developed and patented by German scientists after 50 years of research and 6 years of clinical studies, Activance is the latest advancement in hair cosmeceuticals and the only rhodanide treatment available.

Your hair's rhodanide levels are constantly depleted by day-to-day washing, styling, chemical treatments, stress, health conditions, as well as environmental conditions such as wind and sun damage. This can leave your hair looking dull and lifelss, and eventually lead to it falling out prematurely.
By using Activance, you can instantly restore these rhodanide levels and enjoy thicker, shinier, stronger, easier-to-manage hair.

When introduced into Europe in the late 1990's, Activance became the market leader within 15 months.
Millions of people around the world now enjoy the beneifts of the vital hair care nutrient, Rhodanide.

Because Activance contains natural nutrients, it can be used per directions by men, women (including pregnant and feeding mothers) and children.


  • Promotes healthy hair growth

Activance is a clear, non-sticky, natural lotion that doesnít coat or weigh your hair down.

It can be used as a stand alone product or simply to improve hair quality, or to complement
all other hair & medical products & treatments, ranging from hair colouring to hair medicines & transplants.

Unlike other hair treatments, Activance is an all-in-one, leave in product thatís quick & easy to use:
simply apply daily or every second day, massage in, & style as normal.
The rhodanide then penetrates your hair & rapidly restores it from the inside, out.


It is common knowledge cats and dogs care for their fur/hair using their saliva and when they stop caring for it their fur/hair loses shine. Scientists later found saliva contains the highest level of rhodanide among all body fluids.
For generations, applying egg yolk to washed hair was a well known old wives tale for beautifying hair. Scientists later found egg yolks are the richest source of rhodanide in common food.
Following World War II, people were under-nourished, suffering from extreme shortage of protein and vitamin rich nutrients (i.e. meat and vegetables - a direct and indirect source of rhodanide), resulting in an increase in infectious disease and mortality. As modern antibiotics were not available at the time; products containing rhodanide (such as Orthromin) were given to humans and domestic animals as a way to combat the spread of infectious disease to increase resistance and survival.
  • Rhodanide enriched food was later successfully given to athletes of former East Germany to increase resistance to disease and endurance
  • Sheep and mink showed unexpected but positive side effects of, increased wool production, shine and enhanced fur quality after being fed a rhodanide enriched diet.

The above important observations led scientists to research effects of rhodanide on hair.
For more than half a century German & European Scientists extensivley researched rhodanide; it's biological significance has been documented in over 200 scientific publications worldwide.
In the late 1990's European scientists successfully stabilised and patented Activance with rhodanide to revive thinning, damaged lifeless hair for both men and women.

Activance contains rhodanide; which consists of nitrogen, carbon and sulphur elements (sulphur is nick-named the Ďbeauty mineralí because it keeps hair shiny and healthy).
Hair loses on average 36% of its natural rhodanide level with each washing.
The scalp needs several days to replenish the lost rhodanide, which will automatically lead to rhodanide deficiency if hair is washed daily.
A twice weekly application of rhodanide is sufficient for the hair to establish a rhodanide depot.
Rhodanide, when applied topically to the scalp penetrates along the hair shaft to the roots of the hair.
Rhodanide is a very active anion with different bonding capabilities, enabling participation in many biochemical communications and reaction in cells.

It strengthens and stabilizes the sulphur-hydrogen bonds of the keratin enabling formation of highly-netted keratin connections between cuticle layers and cortex, thus increasing the resistance of keratin structures i.e. strengthening hair from within, resulting in, stable, stronger, more elastic hair, with increased volume, improved manageability and resistance to damage.
Stronger bonding between hair cuticle and cortex also allows improved cuticle scale alignment protecting cortex from damaging external factors.
Proper alignment of hair cuticle scales leaves hair shinier due to improved light reflection.

The natural shine of hair does not result from any topically applied substance but derives from the light reflection of well aligned cuticle scales on the outer layer of the hair.
If cuticle scales are damaged, or not in place the hair lacks protection from all external influences e.g. like a house without a roof. As a natural moisturizing factor rhodanide improves the water binding capability of hair; increasing moisture content by 50%, resulting in an improvement in the hairís physio-chemical qualities such as volume, elasticity, strength and manageability. This is a lasting effect, since hair treated with rhodanide and dried over a period of 24 hours has a higher mass than untreated hair.
Hair remains strong and resistant to mechanical stress and tensile strength is significantly higher compared with untreated hair.
