Understanding the science behind hair loss

Hair loss can be influenced by genetics, hormones, scalp condition, nutrition, stress, medications, and lifestyle factors. Understanding the cause is the first step towards choosing the right care approach.

Hair loss is rarely just a surface problem

Some hair shedding is part of the normal hair growth cycle. However, persistent thinning, a widening part line, a receding hairline, or visible scalp may suggest changes in the scalp or follicle environment.

 

Hair growth is affected by both external and internal factors — including scalp condition, follicle activity, hormones, nutrition, stress, sleep, and medical history.

01.

Scalp Environment

Oil balance, inflammation, sensitivity, and buildup may affect follicle health.

02.

Follicle Activity

Hair follicles cycle through growth, transition, resting, and shedding phases.

03.

Internal Health

Hormones, nutrition, stress, sleep, and medications may influence hair growth.

Common factors that may contribute to hair loss

Hair loss can have more than one contributing factor. For many people, genetics, scalp condition, stress, nutrition, hormones, and lifestyle may overlap.

Genetics

Family history can influence follicle sensitivity and hair thinning patterns.

Stress & sleep

Prolonged stress or poor sleep may contribute to temporary shedding in some people.

Medications or illness

Certain medications, health conditions, or recovery periods may affect hair shedding.

Hormonal changes

Hormonal shifts may affect the hair growth cycle and follicle activity.

Nutrition

Low intake of key nutrients may affect hair quality and growth support.

Styling & product irritation

Tight hairstyles, harsh products, or repeated chemical treatments may stress the scalp and hair shaft.

Scalp inflammation

Irritation, dandruff, oil imbalance, or follicle inflammation may disrupt scalp health.

Postpartum changes

Some women experience increased shedding after pregnancy due to hormonal changes.

Male Hair Loss

  1. Often appears as a receding hairline or thinning crown

  2. May be linked to genetic sensitivity to androgens

  3. Can progress gradually over time

  4. Early assessment may help guide suitable options

Female Hair Loss

  1. Often appears as widening part line or diffuse thinning

  2. May be influenced by hormonal changes, stress, nutrition, or medical factors

  3. May fluctuate during postpartum, menopause, illness, or stress periods

  4. Identifying triggers is especially important before choosing care

Hair health is connected to the whole body

Hair follicles are sensitive to changes in the body. Nutrition, stress, sleep, hormones, metabolism, medications, and overall health can all play a role in hair quality and shedding patterns.

 

An inside-out approach considers both the scalp environment and the internal factors that may affect hair growth.

Nutrition

Protein, iron, zinc, vitamin D, and other nutrients may support normal hair growth.

Hormonal balance

Hormonal changes may influence follicle behaviour and hair density.

Stress

Physical or emotional stress can sometimes shift more hairs into the shedding phase.

Sleep

Poor sleep may affect recovery, stress regulation, and overall health.

Why Assessment Matters

The right approach starts with understanding the cause

 

Because hair loss can be influenced by multiple factors, choosing a treatment without understanding the underlying pattern may lead to inconsistent or disappointing results.

 

A clinical scalp and follicle assessment helps identify visible scalp conditions, thinning patterns, and relevant lifestyle or medical factors, so your care plan can be more targeted.

Scalp Review

Assess oil balance, sensitivity, buildup, and visible scalp condition.

 

Follicle Assessment

Review hair density, thinning pattern, and follicle activity indicators.

 

Health Background

Consider stress, nutrition, sleep, medical history, and lifestyle factors.

 

Care Direction

Recommend next steps based on assessment findings and suitability.
