Hair Loss: When is it normal and when is it excessive?
Hair loss is a completely normal phenomenon that we all notice in everyday life—while brushing our hair, on the pillow, or during washing. But how much hair loss is actually considered normal?
Due to the natural hair growth cycle, an individual may lose between 50 and 150 hairs per day without this being a sign of excessive hair loss. Although this number may initially seem high, it is generally not a cause for concern.
The scalp contains more than 100,000 hairs, meaning that while some hairs shed, others are growing at the same time, resulting in no noticeable reduction in overall hair density.
The amount of hair we perceive as shedding also depends on the type and structure of our hair. For example, longer or denser hair often gives the impression of increased hair loss simply because each shed hair is more visible. Hair thickness, diameter, and volume can all influence the perception of hair shedding, without there being true excessive hair loss.
When does hair loss becomes a cause of concern?
When hair density gradually decreases or shed hairs are not replaced as they once were, this may indicate a disruption in the natural hair growth cycle.
In addition, when hair loss is accompanied by itching, irritation, pain, flaking, or small patchy areas, there may be an underlying scalp condition that requires medical evaluation.
If no new hair growth is observed in the areas where hair is shedding, the loss may not be simple “shedding,” but rather a form of alopecia.
It is also important to note that hair loss presents differently in men and women. In men, androgenetic alopecia typically begins at the frontal hairline or the crown of the scalp, whereas in women it usually appears as diffuse thinning across the top of the head, without recession of the frontal hairline.
In any case, when hair loss is excessive and persistent, medical assessment is essential in order to identify the underlying cause and initiate appropriate treatment in a timely manner.
Causes of hair loss
Excessive hair loss may be caused by multiple factors, often acting in combination. The most common causes include:
Hormonal changes
Fluctuations in hormone levels—such as those occurring after childbirth, during menopause, or due to thyroid disorders—can disrupt the hair growth cycle and lead to temporary hair shedding.
Nutritional deficiencies
Lack of iron, protein, zinc, or B-complex vitamins can weaken the hair root and slow down hair growth, contributing to increased shedding.
Medication and hormonal treatments
Certain medications—such as antidepressants, anticoagulants, treatments for hypertension, or hormonal therapies—may cause hair loss as a side effect.
Poor hair care practices
Frequent use of heat styling tools, chemical treatments, tight hairstyles, or hair extensions can damage the hair follicle and lead to mechanical hair loss, known as traction alopecia.
How is hair loss treated?
If hair loss is excessive, the first step is to identify the underlying cause. In many cases, hair loss is temporary, provided it is addressed correctly and in a timely manner.
1. Consultation with a Specialist
A medical consultant or dermatologist with experience in hair loss conditions can assess the scalp and determine whether the hair loss is within normal limits or excessive.
2. Tests and Diagnosis
Depending on the case, blood tests may be required (e.g. thyroid function, iron levels, vitamins, hormones), along with simple diagnostic methods such as microscopic examination and a trichogram.
3. Treatment and Care
The management of excessive hair loss always depends on the cause:
If a hormonal or nutritional imbalance is present, correcting it may gradually restore normal hair density.
In cases of genetic hair loss, approved treatments are available to support hair growth, such as minoxidil (topical use) or finasteride (oral use, primarily for men).
When hair loss is extensive or permanent, hair transplantation can provide a natural and permanent solution. In addition, non-invasive treatments such as low-level light therapy (Soft Laser) or hair mesotherapy may enhance microcirculation and help revitalize hair follicles.
4. Daily Habits
Prevention plays a crucial role. Gentle hair care—avoiding excessive heat, harsh chemical products, or tight hairstyles—significantly contributes to scalp health. A balanced diet, adequate hydration, and stress reduction are also key factors that support the natural recovery of hair.
