Hair Loss and Balding – Common Causes, Conditions and Treatment Options

Hair loss affects almost everyone at some point in life. Many first notice thinning hair, an increased amount of hair in their brush, or excessive shedding after washing. For some, hair thins gradually over the years, while others may experience sudden and significant shedding, such as telogen effluvium or stress-related changes. Hair loss can reflect normal variation, hormonal factors, genetics, scalp conditions, or a clearly defined alopecia disorder.

In this article, we review different types of hair loss, underlying causes, common misconceptions, and conditions that are often confused with one another. We also outline options for supporting hair quality, including treatments available at MESQ AESTHETICS in Helsinki.

Why Does Hair Fall Out? The Most Common Causes

It is important to understand that hair loss is not a single disease, but a group of different conditions and underlying factors. Common causes include:

Genetic hair loss is often associated with a genetic predisposition to balding. It is commonly referred to as male pattern hair loss or female pattern hair loss.

This type of hair loss is frequently linked to the effects of the DHT hormone. Terms such as DHT blockers, finasteride experiences, and finasteride vs. minoxidil often appear in discussions.

Hormonal causes - hormonal hair loss is especially common in women. Questions such as “What causes hair loss in women?” often lead to evaluating hormone levels.

For example, postpartum hair loss is typically linked to hormonal changes.

Stress or major life changes can trigger sudden and heavy shedding. In stressful situations, the body may shift a large number of hair follicles into the resting phase. A few months later, those same hairs enter the shedding phase, which can result in noticeable hair loss lasting several months.

Scalp conditions, which can directly affects hair quality. Conditions such as fungal infections of the scalp, itching, inflammatory scalp disorders, scalp tenderness, or tight scalp symptoms can impair hair growth. Certain products and chemicals, including strong cleansers, hair dye reactions, or irritants, may worsen scalp symptoms.

Autoimmune conditions, eg. Alopecia is an autoimmune condition in which the immune system targets hair follicles, often causing clearly defined bald patches. Symptoms can range from a single bald spot to more extensive hair loss. It can occur in women, men, and children.

Nutritional factors and vitamins raise questions about which vitamin helps with hair loss or which deficiency causes hair loss are common. Mineral balance and overall nutrition can influence hair growth and density. However, hair loss is not always caused by a single deficiency. A comprehensive evaluation is important before relying solely on supplements.

Types of Hair Loss

Telogen Effluvium

Typically sudden and diffuse shedding. Large amounts of hair may fall out during washing, while the scalp appears normal. Possible triggers may include:

• stress
• illness
• nutritional changes
• childbirth

Genetic Pattern Hair Loss

May present as:

• thinning at the crown
• a receding hairline
• sparse hair at the vertex
• early-onset hereditary thinning

Alopecia Areata

Characterized by:

• round bald patches
• rapidly appearing hairless areas
• autoimmune-related mechanisms

Fungal-Related Hair Loss

Scalp fungal infections may cause flaking, irritation, and hair shedding.

Medication-Induced Hair Loss

Hair loss may also be linked to medication. Common concerns include how quickly hair falls out after chemotherapy, whether antibiotic-related reactions affect hair, and how hormonal medications or antiandrogens influence hair growth.

Hair Loss in Women vs. Men

In women, hair loss is typically diffuse and evenly distributed across the scalp. The hairline often remains intact, while overall density gradually decreases. Hormonal shifts, stress, genetic predisposition, and scalp conditions are common contributing factors.

In men, hair loss is often more clearly patterned and progressive. The hairline recedes, thinning appears at the crown, and over time the top of the scalp may become significantly thinner. This pattern is usually genetically determined.

Conditions Commonly Confused with Hair Loss

Not every scalp or hair change indicates true balding.

Itchy scalp and dandruff

Itching does not automatically mean hair loss. Irritation or flaking can occur without follicle damage.

Naturally thinning hair without balding

Seasonal shedding or changes in hair texture may create the appearance of thinning.

Maturing hairline in young adults

A naturally higher hairline may be mistaken for early balding.

Skin conditions mistaken for alopecia

Round patches on the skin do not always indicate alopecia. For example, the colloquial term “stress alopecia” is often used loosely, even though the underlying cause may be a different skin reaction rather than true autoimmune hair loss.

What Treatment Options Exist?

There is no universal solution, as treatment depends on the underlying cause. Below is a general overview, not a medical recommendation.

Medical Treatments (General Information)

Discussions often mention:

• minoxidil (including topical solutions and use in women)
• finasteride
• medications for male pattern hair loss
• antiandrogens

These options require medical evaluation and supervision.

Scalp Treatments and Supportive Care

People also explore options such as:

• scalp massage
• circulation support
• trichologist assessments

These approaches focus on optimizing scalp health and supporting the conditions necessary for hair growth.

Mesotherapy and PRP Treatment

Many individuals interested in preventing hair loss explore localized scalp treatments designed to stimulate hair follicles.

PRP Therapy (Platelet-Rich Plasma)

PRP utilizes the patient’s own platelet-rich plasma to stimulate hair follicles. At MESQ AESTHETICS, PRP treatments are performed following medical evaluation as part of an individualized treatment plan.

Mesotherapy

Mesotherapy involves microinjections of nutrient, vitamin, and hyaluronic acid-based solutions into the scalp to support scalp condition and the environment for hair growth.

These treatments do not replace medical therapies but may complement a comprehensive approach when the goal is to support scalp health through non-pharmaceutical methods.

Hair loss is a multifactorial condition that may be linked to genetics, hormones, stress, nutrition, scalp disorders, autoimmune mechanisms, medication, or different life stages.

For this reason, questions such as “What causes hair loss?”, “Why am I losing so much hair?”, “How can balding be prevented?” or “What helps with hair loss?” rarely have a single, simple answer.
