Understanding the 3 Root Causes of Hair Loss

1. Hormonal (DHT) Hair Loss

Genetic Sensitivity & Pattern Hair Loss

Hormones act as chemical messengers throughout the body and play an important role in hair growth cycles. One of the most common contributors to hair thinning is sensitivity to dihydrotestosterone (DHT), an active hormone derived from testosterone.

When hair follicles are genetically sensitive to DHT, the follicles can gradually become smaller, producing finer and weaker hairs over time. This process is known as androgenetic alopecia.

In Men:

Male pattern hair loss is commonly associated with genetic sensitivity to DHT and may begin any time after puberty. It typically affects areas such as:

  • Temples
  • Hairline
  • Crown
  • Vertex area

In Women:

Female hormonal hair loss may be influenced by changes in:

  • Estrogen levels
  • Progesterone levels
  • Hormonal transitions such as perimenopause and menopause

As estrogen and progesterone levels decline, DHT may have a stronger impact on genetically sensitive follicles, leading to gradual thinning.

Hormonal hair loss is often a slow process and may take years before noticeable changes appear.

2. Nutritional Hair Loss

When the Body Does Not Have the Building Blocks for Healthy Hair

Healthy hair growth requires adequate nutrition. When the body is lacking essential vitamins, minerals, or nutrients, hair follicles may not receive the support needed for optimal growth.

Two key nutrients often associated with healthy hair function are:

Vitamin D3

Vitamin D3 supports immune function and plays a role in maintaining healthy hair follicle activity.

Ferritin (Stored Iron)

Ferritin is the body’s stored form of iron. Iron helps transport oxygen throughout the body, including to the scalp and hair follicles. Low iron stores may contribute to increased shedding and reduced hair growth.

Nutritional hair loss is often characterized by:

  • Diffuse thinning throughout the scalp
  • Increased shedding
  • Reduced hair density

Nutritional deficiencies can also intensify other forms of hair loss, including DHT-related thinning. Identifying and correcting nutritional concerns is an important part of a complete hair restoration strategy.

3. Inflammatory Hair Loss

Addressing Scalp Health & Internal Inflammation

Inflammation can significantly affect the scalp environment and interfere with healthy hair growth cycles.

Stress, lifestyle factors, and internal inflammation can impact the immune system and create an environment where hair follicles become weakened.

Signs that inflammation may be affecting scalp health can include:

  • Itchy scalp
  • Burning sensation
  • Scalp sensitivity
  • Excess oil or irritation
  • Digestive concerns
  • Increased shedding during periods of stress

Inflammatory hair loss may be associated with conditions such as:

  • Folliculitis
  • Telogen effluvium
  • Seborrheic dermatitis
  • Psoriasis
  • Scarring alopecia

Lifestyle factors that may contribute to inflammation include:

  • Chronic stress
  • Poor sleep patterns
  • Certain medications
  • Excessive exercise without proper recovery
  • Alcohol consumption
  • Nutritional imbalance

Supporting scalp health and reducing inflammatory triggers are important steps in creating the right environment for healthier hair growth.

Understanding Your Hair and Scalp Health

When experiencing hair loss or scalp concerns, working with a technician who has specialized trichology training can help provide a deeper understanding of the factors affecting your hair and scalp health.

A trained trichology technician focuses on evaluating the scalp environment, understanding common contributors to hair loss, and identifying lifestyle, nutritional, hormonal, and inflammatory factors that may impact the hair growth cycle.

Hair Loss in Women During Perimenopause & Menopause

Understanding Hormonal Hair Changes

Hair thinning and increased shedding are common concerns during perimenopause and menopause. As estrogen and progesterone levels naturally decline, hair follicles become more sensitive to DHT (dihydrotestosterone), which can cause follicles to shrink. This often results in finer hair, slower growth, increased shedding, and reduced overall hair density.

Hormones are only one part of the picture. Nutritional deficiencies, stress, inflammation, thyroid imbalances, genetics, and lifestyle factors can also disrupt the hair growth cycle and contribute to thinning.

At MD Laser Clinic, our trichology consultations take a whole-body approach to hair restoration. We assess your scalp health, review potential underlying causes, and develop a personalized treatment plan to help optimize the scalp environment and support healthier, stronger hair growth.

Common signs include:

  • Increased daily hair shedding
  • A widening part line
  • Thinning around the crown or temples
  • Finer, weaker hair strands
  • Slower hair growth
  • Dry, itchy, or sensitive scalp

Early assessment can help identify contributing factors before hair thinning becomes more advanced, allowing for more targeted treatment and long-term scalp health.

Hair Loss & Trichology FAQ

Trichology is the study of hair and scalp health. A trichology-trained professional focuses on understanding the factors that may contribute to hair thinning, shedding, scalp irritation, and changes in hair quality.

A trichology approach looks beyond the symptoms and considers possible influences such as hormonal changes, nutrition, scalp health, inflammation, and lifestyle factors.

A technician with trichology training helps assess your hair and scalp concerns by looking at possible contributors to changes in your hair growth cycle.

They may evaluate:

  • Scalp condition and health
  • Hair thinning patterns
  • Hair shedding concerns
  • Lifestyle factors
  • Nutritional considerations
  • Possible hormonal influences
  • Inflammatory scalp concerns

The goal is to help you better understand your hair concerns and create a personalized hair wellness plan.

Hair loss can have many contributing factors, and it is not always caused by genetics alone. A trichology-trained technician can help identify patterns and possible triggers that may be affecting your scalp and hair growth.

Understanding the possible cause is an important first step in determining the right approach for your individual needs.

No. While genetics and DHT sensitivity are common contributors to hair loss, other factors may also play a role.

Hair thinning can be influenced by:

  • Hormonal changes
  • Nutritional deficiencies
  • Stress
  • Inflammation
  • Scalp conditions
  • Lifestyle factors

Many people experience more than one contributing factor at the same time.

Yes. Hormonal changes during perimenopause and menopause can affect the hair growth cycle.

As estrogen and progesterone levels decline, some women may notice:

  • Increased shedding
  • Thinner hair strands
  • Reduced hair density
  • More visible scalp areas
  • Changes in hair texture

A trichology assessment can help identify possible factors contributing to these changes.

Hair follicles require proper nutrients to function optimally. Two commonly evaluated nutrients related to hair health include:

Ferritin: A storage form of iron that supports oxygen delivery throughout the body, including the hair follicles.

Vitamin D3: Plays a role in immune function and healthy follicle activity.

Other nutritional factors, including protein intake, zinc, and overall dietary balance, may also influence hair health.


Your scalp is the foundation for healthy hair growth. Signs that your scalp may need attention include:

  • Itching
  • Burning sensation
  • Sensitivity
  • Flaking
  • Excess oil
  • Redness or irritation
  • Increased shedding

Addressing scalp health is an important part of supporting the hair growth environment.

The potential for improvement depends on the condition of the hair follicles and the underlying causes of hair loss.

Early assessment can help identify contributing factors and determine what steps may help support healthier hair growth and scalp wellness.

A trichology-trained technician can provide additional insight into hair and scalp health and help identify possible factors contributing to hair changes. When appropriate, they can also work alongside medical professionals to support a more complete approach.

A comprehensive hair wellness assessment may include evaluating scalp health, lifestyle factors, nutrition, hormonal influences, and other possible contributors. We can also provide referrals for microscopic blood analysis, which may offer additional insight into internal factors and help identify possible root causes affecting hair and overall wellness.
