Men are more susceptible to pattern hair loss.

Did you know

Up to

8 in 10

men may experience androgenetic alopecia, commonly known as pattern hair loss, during their lifetime.1

42%

The pattern starts earlier than most people think.

Among men aged 18–49 in one community study, moderate‑to‑extensive male pattern hair loss was already this common.2

58%

For Indian men, the numbers are equally striking.

Among 1,005 men aged 30–50 in one population study, androgenetic alopecia was this common.3

Pattern hair loss prevalence by age

In the same study, pattern hair loss became more prevalent with age:

30–35 47.5%
36–40 58.7%
41–45 73.2%

So why is male hair more vulnerable?

01 The androgen environment

Male hair exists in a different biological environment.

Men carry a substantially higher androgen load. Within the scalp, an enzyme called 5α‑reductase converts testosterone into dihydrotestosterone (DHT), a far more potent androgen.

In genetically susceptible follicles, DHT binds to androgen receptors and quietly rewrites the follicle’s instructions.

The result?

Miniaturisation.

Over repeated cycles, a susceptible follicle produces hairs that are progressively shorter, finer and less robust until the hair you grow stops looking like the hair you had. This is why pattern loss is progressive; the follicle itself changes, cycle after cycle.

But DHT is only part of the story.

02 The living follicle

Hair growth is a biological system.

A hair follicle is more than an androgen receptor; it is a living mini‑organ.5 Healthy growth depends on multiple biological systems working together: signalling, regeneration, structural support, cycle regulation and communication between different cell populations.

Dermal papilla cells act as an important signalling centre, helping regulate follicular activity and the hair‑growth cycle.

Epithelial and mesenchymal cells continuously exchange biological signals that influence growth, regression and regeneration.

Follicular stem and progenitor cells help enable repeated regeneration across successive hair cycles.

Healthy hair depends on the coordinated transition between anagen, catagen and telogen - growth, regression and rest.

The matrix surrounding follicular cells provides both structural architecture and biochemical signals that influence follicular behaviour.

Hydration, barrier condition, oxidative balance and the local environment surrounding the follicle all influence the conditions in which hair grows.

Hair loss is what you see. The biology beneath it is a system.

03 The scalp

Why scalp health matters?

The hair you see starts in the scalp you don’t. It does not begin at the surface. Before a hair fibre emerges, it develops within the follicular environment beneath the scalp. The scalp therefore acts as an incubatory environment for pre‑emergent hair, meaning the conditions surrounding the follicle can influence the hair before it becomes visible. Healthy‑looking hair starts below the surface.

A healthy scalp environment depends on multiple conditions working together.

01

Barrier health

Hydration stays in and everyday stress stays out, creating stable working conditions for the follicle.

02

Oxidative balance

Protection for the scalp and follicular environment from excessive oxidative stress.7

03

Follicular environment

The biological surroundings the follicle actually lives and works in, kept liveable.

04

Quality & retention

The environment precedes the visible fibre and quietly shapes it.

Scalp optimisation isn’t the final step. It’s the foundation.

04 The root environment

A follicle doesn’t grow in isolation.

Every follicle exists within a specialised biological architecture.

The extracellular matrix surrounds follicular cells, providing structural support while also carrying biochemical signals.

The root environment also depends on coordinated communication between the dermal papilla, surrounding cells and the follicular stem‑cell niche. Together, these systems help regulate whether the follicle grows, rests or rebuilds.

Healthy growth requires more than a single growth signal. It asks for communication, structure, regeneration, cycle control and a healthy scalp environment.

05 The delivery

Why delivery matters?

The right active is only half the equation. A topical formulation must first navigate the scalp barrier and reach the environment where it is intended to act. Hair follicles can also function as specialised pathways and reservoirs for topical compounds.6

So formulation science should ask two questions:

01

What should we target?

The pathways and conditions that shape male pattern loss.

Surface Where the biology lives Deep down

02

How should we deliver it?

Beyond the barrier, through the follicular pathway, to the root environment.

Biology + delivery. Not just ingredients.

06 The formulation

Why Enigma exists

Different biology requires a different solution. We did not begin with a list of trending ingredients and build a formula around them. We began with the biology. We mapped the system. We built Enigma.

  • The androgen environment
  • Hair‑cycle regulation
  • Cellular signalling
  • Follicular vitality
  • Root & matrix support
  • Scalp barrier health
  • Oxidative defence
  • Delivery of actives

Explore how Enigma turns this biology into a targeted system.
