ANAGAIN™: HOW IT SUPPORTS THE GROWTH CYCLE

This article explores AnaGain™ and its role in the natural hair growth cycle, with a focus on anagen, density and fuller-looking hair.

Hair does not grow continuously at the same rate. Each follicle moves through a natural cycle of growth, transition and rest, and the balance between these phases has an important influence on the appearance of hair density over time.

This is where AnaGain™ becomes particularly interesting.

Derived from organic pea sprouts, AnaGain™ is a cosmetic active developed around the biology of the hair follicle and, specifically, the signalling environment of the dermal papilla. Its purpose is to support the natural hair growth cycle by encouraging signals associated with the initiation of new hair growth.

Rather than approaching hair simply from the surface, AnaGain™ focuses on the growth cycle beneath it.

WHAT IS ANAGAIN™?

AnaGain™ is a cosmetic active based on organic pea sprout extract. It was developed to interact with signalling pathways within the hair follicle, particularly those associated with the dermal papilla.

The dermal papilla is a specialised structure at the base of the hair follicle that plays an important role in regulating hair growth. AnaGain™ has been studied for its ability to influence the expression of FGF7 and Noggin, signalling molecules involved in the initiation and regulation of the hair growth phase.

This gives AnaGain™ a more specific role than simply being described as a botanical hair-growth ingredient.

Its focus is the hair growth cycle itself, making it particularly relevant to formulations designed around hair fall, density and the appearance of fuller hair.

WHAT IS THE ANAGEN PHASE?

The anagen phase is the active growth phase of the hair cycle.

During anagen, the hair follicle is actively producing the hair fibre. The follicle subsequently moves through transitional and resting phases before beginning another growth cycle.

The relationship between these phases matters because the proportion of follicles in active growth compared with those in later stages influences the overall appearance of hair density.

AnaGain™ was developed specifically around this concept. Its mechanism is designed to influence signalling within the dermal papilla in a way that supports the natural transition into the growth phase.

This is why the anagen-to-telogen ratio is relevant when discussing AnaGain™. Rather than looking only at how many hairs are visible, the ratio provides insight into how many follicles are in active growth relative to those in the resting phase.

HOW DOES ANAGAIN™ SUPPORT THE HAIR GROWTH CYCLE?

AnaGain™ works through a distinctive biological pathway involving the dermal papilla.

Research on the ingredient found that pea sprout extract increased the expression of FGF7 and Noggin, signalling molecules associated with the initiation of a new hair-growth phase.

In a clinical study, a 4% AnaGain™ preparation was applied to a defined scalp area twice daily for three months. Phototrichogram analysis showed a reduction in telogen hair density and an increase in anagen hair density. The anagen-to-telogen ratio increased from approximately 4 to 7.2 over the study period.

These findings provide an interesting indication of how AnaGain™ may influence the balance of the hair growth cycle.

The evidence should still be viewed within its limitations. The clinical study was relatively small, and results from a specific ingredient preparation cannot automatically be applied to every finished cosmetic formula containing AnaGain™.

What makes the ingredient compelling is the mechanism it is designed to target: supporting the signalling environment associated with active hair growth.

ANAGAIN™, HAIR FALL & VISIBLE DENSITY

Hair fall and hair density are closely connected to the hair growth cycle.

When a greater proportion of follicles are in active growth, the overall appearance of the hair can be influenced over time. Conversely, a greater proportion of follicles in later stages of the cycle can contribute to changes in visible density and shedding.

AnaGain™ is designed around this relationship. Its clinical research has reported an improved anagen-to-telogen ratio, alongside changes associated with hair density and hair loss.

This makes AnaGain™ particularly relevant to formulas created around hair fall control, density and fuller-looking hair.

It is also why describing AnaGain™ simply as an ingredient that “makes hair grow” misses the more interesting part of its role.

Its distinction lies in its relationship with the cycle through which the hair grows.

WHY THE HAIR GROWTH CYCLE MATTERS

Healthy-looking hair is not determined by a single moment in time. It is the result of repeated cycles of growth, transition and rest taking place across thousands of individual follicles.

This makes the growth cycle an important consideration when developing hair-care formulas around hair fall and density.

AnaGain™ offers a cosmetic approach centred on this cycle, while other ingredients can address complementary aspects of the scalp and hair.

A sophisticated formulation can therefore consider the scalp environment · hair growth cycle · root support · hair fibre quality · and visible density together.

This broader perspective matters because fuller-looking hair is not simply about encouraging growth. It is also about maintaining the quality and resilience of the hair that is produced, while caring for the scalp from which it grows.

AnaGain™ has a particularly defined place within this approach because its role is centred on the biological signalling associated with the hair-growth phase.

ANAGAIN™ IN THE HWB SCALP RESET DUO

The HWB Scalp Reset Duo brings AnaGain™ into both stages of a deliberately designed scalp-first cleansing ritual, allowing the ingredient to sit within a broader approach to scalp and root care rather than functioning in isolation.

The first stage is the Pre-Shampoo Scalp Whip Cream, where AnaGain™ is combined with Procapil™ and Biotin alongside Quassia Vinegar and Crinipan® PMC Green. The formula is designed to help loosen stubborn buildup and impurities while bringing targeted scalp and root care into the first stage of the ritual.

The 100% Pure Silicone Massage Comb enhances this step, helping distribute the pre-shampoo formula across the scalp while gently massaging and helping loosen accumulated buildup.

The second stage is the Hold the Hairline Biotin Shampoo, where AnaGain™ continues as part of the formulation alongside Biotin, Caffeine and Saw Palmetto. Niacinamide and Green Tea further support the scalp-focused system, while Salicylic Acid, Zinc PCA and Climbazole address buildup, excess sebum and dandruff.

The formulation also gives equal consideration to the hair fibre. Rice Peptides, Silk & Quinoa Proteins, Amino Acids and Pro-Vitamin B5 support the strength, resilience and feel of the strands, helping deliver softness, manageability and a more refined finish after cleansing.

Across both stages, AnaGain™ brings the same distinctive focus: supporting the natural hair-growth cycle and the anagen phase.

This continuity is intentional. The scalp is not treated as a surface to cleanse and then forget. It is the environment surrounding the roots and the starting point of the hair-growth cycle, making it an essential part of a complete hair-care approach.

The Duo therefore brings together two complementary objectives: reset the scalp thoroughly and support the conditions around the roots.

With AnaGain™ present across both formulas, the growth-cycle perspective is carried through the ritual, while each stage performs its own role. The pre-shampoo prepares and resets the scalp; the shampoo continues the cleansing and targeted care.

The result is a more considered approach to the hair-growth environment, built around the principle that healthy-looking, fuller hair begins with how you care for the scalp and roots from the very first step.
