How was HAIRPRINT invented?

Dr John Warner of the Warner Babcock Institute for Green Chemistry (Massachusetts) is the mastermind behind HAIRPRINT. An honorary chemist, Dr Warner, has received many awards including the Perkin Medal – widely recognised as the highest honour in American chemistry.

Over a four-year period, Dr Warner was able to perfect a safe, non-toxic process that imitates what hair follicles do – infuse hair with its natural pigment.

When Warner began his journey to find a natural way to colour hair, he began with working on grey hair cuttings that took on varying shades, ranging from light brown to jet-black.

Unable to achieve consistent results, Warner inquired what the problem was and was advised by his supplier that the cuttings were not from a single donor. They were in fact from many sources. That is when Warner realised that HAIRPRINT might be restoring natural colour to the hair.

He tested this theory by applying it to his hair, which had gone grey as a young man at Princeton. In just 80 minutes, it returned his hair to the same colour he remembered having thirty years before applying the treatment. HAIRPRINT was born.

Once exposed to HAIRPRINT, the hair’s natural pigment though currently, grey hair accepts the pigments which are being restored to the hair via the treatment, resulting in your natural colour appearing. Dr Warner knew this when he began experimenting. What he did not expect was how HAIPRINT transformed the condition of the hair, making it stronger, giving it more body and lustre.

Rather than thinking of HAIRPRINT as a colouring agent, think of it as a Hair Healing System that just happens to restore grey hair to its natural colour.

What causes hair to go grey?

Before we can understand what causes grey hair, we must look at how hair gets it colour. 

Melanogenesis is the process of melanin production by melanocyte cells. The result of the production, known as pigments,  we find pigment in our skin, hair and eyes. Melanogenesis can be used to explain how the sun colours your skin, how your eyes get their colour and how our hair colours in its follicle.  When hair goes grey, the body has stopped producing natural melanin.

HAIRPRINT mimics this process using toners to nudge the colour restoring treatment to lean in one direction or another. Your hair however ultimately chooses the colour.

Some of the known causes of grey hair outside of natural ageing process include:

  • Diet — A lack of certain vitamins and minerals can accelerate grey hair, especially vitamins B-12, C, E, zinc and copper. Anaemia and thyroid conditions can also be a cause.  Junk food can cause oxidative stress to the body. Eating well is the lesson.
  • Stress – Stress as a result of lack of sleep, overworking, extreme shock, certain pharmaceuticals, and smoking can accelerate changes in the hair. Chemotherapy has been known to turn hair grey almost overnight.
  • Hair dyes — Powerful scavengers are found in permanent hair dyes that grab electrons wherever they can causing oxidative stress and sensitization that can lead to serious allergies, as well as potentially damage your DNA. The molecules in hair dye are so small that they could easily pass through the skin into your bloodstream.  We do not know what hair dyes do inside the body. There are two basic types of cells in the follicle: keratinocytes which make hair fibre and melanocytes producing pigment. Both can be affected by the constant exposure to toxic chemicals. Ironically, dyeing may accelerate the greying of hair and can damage the capacity of follicles that produce the healthier hair.
  • Genetics — People of different ethnic origin tend to go grey at various rates. Caucasians go grey the fastest. Slower than Caucasians are Asians. The most fortunate are African-Americans who become grey later in life. Some indigenous people, however, can go well into their eighties with their original hair colour.
  • Age — Fundamentally hair changes with age, sooner for some, later for others. Half the population has 50% grey hair by the age of fifty.

Grey hair is beautiful, and there is nothing more gracious than embracing and accepting our age. With HAIRPRINT you are in control of how much grey you want to cover.

Some of our clients deliberately do not colour the hairline because the overall look is so natural with HAIRPRINT, allowing you to keep that ” distinguished look”  that grey hair provides for some. Some feel and look better and are more comfortable with less grey. HAIRPRINT allows you to enhance your natural beauty without causing you harm.


How is HAIRPRINT different to hair dyes?

HAIRPRINT is different to hair dyes. In conventional colouring, the chemical known as phenylenediamine (PPD) is the key covering and colouring grey hair.

Hair dyes work by opening up both the cuticle and the cortex of the hair using ammonia or MEA, removing the natural colour (pigment) that is there and placing a new colour or rather a coal tar dye, in its place. Couplers, oxidizers and harsh chemicals are also present in conventional dyes.

HAIRPRINT, however, replaces the missing pigment common to darker hair colours (light brown to black hair)

During the colour restoration treatment:

  • New eumelanin is synthesised within the cortex structure of the hair restoring its natural colour.
  • This process is called melanogenesis and occurs regularly in the human body.
  • HAIRPRINT creates the precursors of eumelanin, relatively small monomers that penetrate the cuticle layer into the cortex.
  • Forming eumelanin pigments that polymerise becoming too large to be washed or abraded out.

What is HAIRPRINT and how does it work?

HAIRPRINT Colour Restorer is a natural colour treatment restoring the natural eumelanin – aka pigment or colour, to your hair.

We’re giving you the hue you were born with, the way nature intended. The pigment that creates the colour of your hair lives in the hair follicle. HAIRPRINT Colour Restorer imitates that biological process and adds back the natural colour (eumelanin) from the outside. Working with vegetable extracts from velvet beans, we have created a simple, safe and harmless way to restore grey hair.

We do not use any dyes, PPD, PTD, coal tars, paraben’s, high levels of ammonia or peroxide to strip colour. There is no smell, itching or burning, treatment restores and strengthens the hair while adding body and improving the natural shine of your hair, where applied. The eumelanin pigment, naturally produced in hair, is a protein and while your hair changes from grey back to its natural colour where applied, you are also adding protein to the hair.

HAIRPRINT works by restoring the natural pigment to your hair. Because all ‘hair prints’ are as unique as fingerprints, the structure of your ‘hair print’ determines how the pigment arranges itself. It also determines how light refracts, and refraction determines how we perceive colour. Dyes do not do this. That is why hair saturated with natural pigment always looks different and better than hair that is chemically dyed.

During the HAIRPRINT treatment, new eumelanin synthesises within the cortex of the hair. This process is called melanogenesis and happens continuously within the body.
