Great Lengths Regime


An expertly curated 4-step regime that's specifically designed to target the scalp, hair follicles and hair lengths. These four innovative, award-winning products work in tandem to nourish scalp skin, repair and protect strands, and rebuild the natural strength of hair in order to maximise hair growth.

This best-selling 4-step regime effectively helps to stimulate follicles and optimise the dermatological condition of the scalp for stronger, fuller, healthier hair growth.

Start with the Clarifying Scalp Scrub to decongest follicles and prime the scalp for utmost ingredient absorption by buffing away build-up.

Next, cleanse the scalp with the Strengthening Silk Protein Shampoo to strengthen and fortify fine and thinning hair from breakage, while also shielding it from environmental damage.

To follow, use the Strengthening Essence-Conditioner, whose ultra-lightweight texture nourishes and repairs fragile hair and scalp skin without leaving hair greasy or weighed down.

Finish with the best-selling Follicle Boost Hair Density Serum that works to stimulate the scalp, promote cell renewal and decongest follicles for maximised hair growth. It innovatively combats fallout by blocking the production of DHT, fostering thicker and fuller hair.

All products are dermatologically tested, cruelty-free, and suitable to use during pregnancy and breastfeeding.

Clarifying Scalp Scrub

Dampen hair and apply a small amount across different sections of the scalp. Gently massage in small circular motions. Rinse thoroughly.

Strengthening Silk Protein Shampoo

Using a walnut-sized amount, massage into the scalp and hair. Rinse thoroughly, then repeat.

Strengthening Essence Conditioner 

After cleansing, use a walnut-size amount (longer hair may need slightly more) and gently massage into the scalp and hair. Leave for two minutes, then rinse thoroughly with cold water for extra shine.

Follicle Boost Density Serum

Apply one to two drops of serum on the hairline and along the parting, spaced evenly. Gently massage across the scalp until the serum has fully absorbed.

87% noticed less hair fall
80% agreed their hair felt stronger

My regrowth is amazing. Thick, growing very quickly and feels beautifully soft. I am very happy.

The top-scorer for anti-breakage, 87% of testers noticed less hair fallout and 80% said hair felt noticeably stronger. Hair also felt softer after use, making it easier to detangle and style, while those with natural curls saw a reduction in flyaways. An impressive 93% said they would continue to use these products after the trial. - Good Housekeeping Institute


As the holy grail anti-ageing active ingredient, retinol proliferates cell growth, collagen synthesis, minimises sebum production and boosts the smoothness of the scalp. By resurfacing the scalp, speeding up cell turnover and decongesting follicles, it improves the absorption of other hair growth boosting ingredients.

As a vegan alternative to silk peptides, this pioneering ingredient fortifies hair from the root. It delivers a breathable barrier to the hair and scalp - protecting against external aggressors such as pollution, sea or chlorinated water, irritants and bacterial adhesion. Vegan silk peptides improve carbon particle removal up to 83% in one use, improve hair colour protection by 35%, and repair heat damage by 72%. The application of vegan silk peptides yields scientifically-proven results, and fosters a stronger, healthier and more resilient scalp and hair environment, while improving the hair’s smoothness and shine, leaving it silky to the touch.

This gentle yet effective ingredient has been scientifically proven to block the 5-alpha reductase enzyme that produces DHT, a byproduct of testosterone that causes hair loss. It initially targets the catagen and telogen phases, working to minimise excess shedding. It also boosts the growth of new follicles leaving the telogen phase and entering into a new cycle of the anagen phase. This powerful extract also stimulates follicles, delivers nutrients and boosts circulation to the scalp.


The Follicle Boost Hair Density Serum works to enhance and target the natural hair growth cycle, extending the anagen (growth) phase, shortening length of the telogen (shedding) phase and stimulating dormant hair follicles with concentrated active ingredients.

addressing hair & scalp health at the root


The relationship between hair and hormones starts as we are born and continues through every stage of life. From DHT to oestrogen, hormones play one of the most vital roles in our hair and scalp health. The hair growth cycle and the hair follicle structure are directly affected by the hormones in our bloodstream. Fluctuations in sex hormones, stress hormones and thyroid hormones all have various effects on the hair and scalp, and are often the culprits of sudden disruptions in their their health.


Stress compromises the health of your body in a variety of ways, the retention of your hair being one of them. Exposure to stress hormones over many weeks reduces hair growth as hair follicles remain in an extended telogen (resting) phase, a condition known as Telogen Effluvium, whereby up to 70% of growing hairs can abruptly shift into the resting phase (versus the normal 15% that elicits shedding before a new anagen phase).


Through a process called oxidative stress, environmental aggressors (such as cigarette smoke, pollutants, UV radiation or even certain products or foods) can damage various cellular structures in the hair follicle. Oxidative stress breaks down cell tissue and causes DNA damage, which can result in inflammation. Research has shown that oxidative stress also contributes to hair loss by impairing the scalp’s ability to support healthy cell renewal, and in turn, healthy hair growth.


Hair cells are the second fastest-dividing cells in the human body. Each individual has roughly 120,000 hairs on their scalp, all of which require nourishment and fuel to grow and proliferate. Nutritional deficiencies, particularly in iron, zinc, Vitamin D, biotin and Vitamin B12, can impact the hair’s structure, follicle development, immune cell functioning, and ultimately, hair growth. By supporting healthy nutrition, you can support a healthy hair growth cycle.


As we age, the body undergoes many changes and fluctuations, with our hair being no exception. Turning grey is just one of the many changes that confront our hair as we age. In fact, hair ageing affects hair colour, hair curvature, hair diameter and the structural properties of the hair fibre. Research suggests that over 52% of women will experience some form of hair loss by the age of 50, and by the age of 60, approximately 80% will undergo changes in their hair density.

When can I expect to see results?

The average hair’s growth rate is around 1cm a month. The Follicle Boost Hair Density Serum enhances the natural hair growth cycle, activating dormant hair follicles with concentrated active ingredients. Here’s what you can expert with daily use:

Months 1-2

Initially targets the catagen (transition) and telogen (shedding) phases. You’ll notice less excess shedding.

Months 3-4

Boosts the growth of new strands leaving the telogen phase and entering into a new cycle of the anagen (growth) phase. You’ll begin to see fuller hair.

Months 5-6

Prolongs the anagen phase, resulting in visible hair growth, thickness and fullness.

It is important to approach your hair growth journey with patience and consistency, with the understanding that it forms part of the broader hair growth cycle.

Why am I losing hair after giving birth?

Many women experience hair loss after giving birth due to a natural but sudden decline in the hormone oestrogen. In the first weeks postpartum, hairs enter the shedding phase in what they call a ‘synchronous wave’, reaching about 30% after nine weeks, which explains how most postpartum hair loss is experienced two to four months after childbirth. Luckily, postpartum hair loss is very common and only temporary. Hair growth can be cultivated with the right routine.

How long does a bottle of serum last?

How long the serum lasts depends on the frequency that you use it, but a little goes a long way. If you use it as a daily treatment, it should last around 6-8 weeks (on average). If you use it to spot treat areas of concern, it can last longer, around 3 months on average. Once opened, the life of the serum lasts between 18-24 months.

Should I apply the serum to wet or dry hair?

The serum can be applied when hair is dry, damp or towel-dried after a shower. We recommend applying the serum to damp or towel-dried hair to optimal absorption and to prevent any oily residue.

Can I use the serum while pregnant or breastfeeding?

All products are dermatologically tested, suitable to use during pregnancy and breastfeeding and cruelty free.
