Causes and treatment of hair color changes: what you need to know
About the symptom
Change in hair color can be a symptom of various physiological and pathophysiological processes in the body. This phenomenon can occur as a result of natural age-related changes or as a result of serious diseases. For example, as people age, many experience graying associated with a decrease in melanin production — the pigment responsible for hair color. However, if the change in color occurs suddenly and without apparent reason, it may signal underlying health issues such as vitamin deficiency, metabolic disorders, or even thyroid diseases.
Moreover, hair color change can be related to external factors, such as exposure to chemicals, ultraviolet radiation, or unfavorable environmental conditions. Certain stresses and emotional experiences can also lead to hair depigmentation. In such cases, it is important to consult a trichologist or dermatologist to identify the cause and prescribe appropriate treatment. Seeking medical help early can prevent serious consequences and restore hair health.
Diseases
Changes in hair color can be a sign of various diseases that require attention and diagnosis. One of the most common conditions is albinism, in which there is a lack of pigment in the hair, skin, and eyes. No less significant is vitiligo — an autoimmune disease where melanin production stops in certain areas of the skin, which can lead to the discoloration of hair in these zones. Additionally, changes in color may indicate a deficiency of vitamins and minerals, such as zinc, copper, or vitamin B12.
It is important to pay attention to other potential diseases that may manifest as changes in hair color. For example, conditions such as hypothyroidism and thyroid problems can cause hair lightening. Also, in some cases, changes in color may be associated with prolonged stress or hormonal changes. If such symptoms are observed, it is recommended to consult a doctor for diagnosis and to determine possible causes.
- Albinism
- Vitiligo
- Hypothyroidism
- Vitamin deficiency (e.g., B12, zinc, copper)
- Autoimmune diseases
- Hormonal changes
- Stress
Diagnosis
Change in hair color can be a symptom of various diseases, and a comprehensive diagnosis is required to determine the cause of this phenomenon. First and foremost, the specialist conducts an external examination and interviews the patient to identify possible factors, such as stress, changes in diet, heredity, and others. Based on the collected information, the doctor may recommend additional tests to help narrow down the possible causes of hair color change.
Among the diagnostic services that may be offered to determine the reasons for hair color change, the following can be highlighted:
- Blood tests to check vitamin and mineral levels;
- Trichoscopy — a diagnostic examination of the condition of hair and scalp;
- Scalp biopsies for further laboratory analysis;
- Allergy tests for reactions to cosmetic products or medications;
- Genetic testing to identify hereditary diseases.
Early diagnosis and accurate identification of the causes will help effectively address the issue, prevent possible complications, and restore the hair’s natural color and health.
Which doctor to consult
Change in hair color can be a sign of various diseases or conditions related to the health of the skin, hair follicles, or overall body health. Therefore, it is important to consult a specialist who can correctly identify the cause of the color change and prescribe appropriate treatment. Usually, the first step is a consultation with a dermatologist who specializes in skin and hair diseases. They will perform a visual examination and may order additional tests to determine the cause of the change in hair color.
In some cases, a consultation with a trichologist may be required—a doctor who deals with hair and scalp issues. They study the condition of the hair in more detail and can offer specialized diagnostic methods, including analyses of hair and skin that help detect microbiological or infectious diseases. If the color change is related to hormonal disorders or other systemic diseases, you may need to consult an endocrinologist or other specialized professionals.

Types of Hair Color Change
Hair color change can be caused by various factors, ranging from natural aging processes to environmental influences or diseases. Several main types of hair color change can be observed in people. One of the most common is bleaching, when hair loses its natural color, becoming lighter. This can occur both due to sun exposure and the use of chemical styling or coloring products.
Another type of color change is the appearance of gray hair, which is usually associated with age and a decrease in melanin production. However, gray hair can also appear at a younger age due to genetic factors or stressful situations. There are also cases when hair acquires unnatural shades, for example, with Certain Glow or with the use of low-quality dyes. It is important to note that a change in hair color can be a symptom of various diseases, so it should be considered in conjunction with other health manifestations.
- Hair bleaching
- Appearance of gray hair
- Change in hair color due to stress
- Abnormal shades due to dye exposure
- Genetic changes in hair color
Reasons for Hair Color Changes
Changes in hair color can be associated with various factors that affect the health of the hair and the body as a whole. One of the main reasons for this phenomenon is pigmentation disturbances caused by a deficiency of melanin. Melanin is a natural pigment that gives color to the hair, skin, and eyes. With age, as well as under the influence of certain diseases, the production of melanin may decrease, leading to gray hair.
In addition, changes in hair color can be the result of external factors such as frequent dyeing, chemical straightening or perming, as well as the use of aggressive care products. Ultraviolet rays can also have a negative impact on hair, causing fading and structural changes. Little-known or irreversible changes in hair color may signal the presence of internal diseases, so it is important to consider all factors affecting the appearance of hair.
- Metabolic disorders
- Hormonal imbalance
- Stress and psychological disorders
- Vitamin and mineral deficiencies
- Autoimmune diseases
- Dieting or poor nutrition
Common Related Pathologies
Change in hair color can be a sign of various diseases and conditions that require the attention of specialists. For example, a change in hair shade may accompany significant pathologies such as vitiligo, which involves the loss of pigmentation in the skin and hair. This condition, associated with autoimmune processes, can cause significant changes not only aesthetically but also affect the patient’s self-esteem.
Other disorders, such as hypothyroidism, can also reflect on hair color. In this disease, a decrease in thyroid gland functions is observed, which leads to a change in metabolism and can cause changes in the texture and color of hair. Related pathologies can have serious health consequences, so it is important to consult a doctor for diagnosis and adequate treatment.
Common Pathologies Associated with Changes in Hair Color:
- Vitiligo
- Hypothyroidism

Expert Opinion
Hair color change is a process that can be triggered by many factors, including genetic, hormonal, and external conditions. According to trichologists, hair can lose its natural color due to a decrease in melanin levels, which often occurs with age. However, in recent years, there has been a trend where color changes in hair become pronounced even in young people, which may signal certain diseases or even stress. It is important to realize that this is not just a cosmetic issue, but also a medical problem that requires attention.
Experts advise not to ignore changes in hair color, as they may be associated with pathologies that need diagnosis and treatment. For example, vitiligo, anemia, or hormonal disorders can manifest in this way. Additionally, trichologists emphasize that professional help can be extremely useful in determining the true causes of the change and prescribing appropriate treatment. Maintaining hair health is an important task for anyone who cares about their appearance and the overall condition of the body.
Treatment of Hair Color Changes
Changes in hair color can be caused by various factors, including genetic reasons, hormonal changes, and external influences. It is important to understand that the treatment of this symptom should be individualized and based on the underlying causes, which will help protect the health of the hair and scalp. If there is an unexpected change in hair color, it is advisable to consult a doctor to establish a diagnosis and select therapeutic methods.
First, it is necessary to conduct diagnostic procedures to determine the root cause. In some cases, methods such as hormone analysis, dermatoscopy, or skin biopsy may be required. Based on the obtained data, the doctor will be able to create an individualized treatment plan, which may include medication therapy, dietary adjustments, and the use of specialized hair care products.
The most common methods for treating hair color changes include:
- Medication therapy aimed at normalizing metabolism;
- Restorative procedures for hair, such as mesotherapy or PRP therapy;

Complications
Changes in hair color can be not only a cosmetic issue but also a sign of various diseases and conditions of the body. The state of hair and its color may indicate internal problems, such as vitamin deficiencies, metabolic issues, or hormonal imbalances. A lack of certain nutrients, such as B vitamins, can lead to the loss of hair pigmentation, which, in turn, causes premature graying. Other conditions, such as chronic stress or thyroid diseases, can also affect hair color, making it lose its richness or change tone.
In addition, changes in hair color can be caused by external factors, such as improper use of chemical hair care products. The dyeing process can damage the hair structure, leading to brittleness and loss of natural shine. In some cases, an allergic reaction to the dye may occur, resulting in rashes or irritation on the scalp. To avoid these complications, it is important to undergo timely examinations and consult with professional specialists in dermatology or trichology.
- Alopecia (baldness)
- Improper functioning of the thyroid gland
- Chronic stress
- Metabolic issues
- Allergic reactions to chemicals
- Dermatitis and other skin diseases
FAQ
What can cause a change in hair color and when should you see a doctor?
Changes in hair color can be caused by various factors, including genetic characteristics, age, hormonal changes, nutrient deficiencies, as well as diseases such as vitiligo or albinism. If you notice a sudden change in hair color accompanied by other symptoms, such as itching, hair loss, or changes in texture, this may indicate a serious issue. In such cases, it is important to consult a doctor for diagnosis and to identify the cause in order to receive appropriate treatment and prevent further changes.
How can a change in hair color be related to overall health?
Changing hair color may be related to overall health, as many diseases or disorders in the body can affect the appearance of hair. For example, deficiencies in vitamins and minerals, such as vitamin B12, copper, or zinc, can lead to graying or color change. Thyroid diseases can also affect hair pigmentation, causing darkening or bleaching. In some cases, even stress or serious psychological experiences can be the reason for hair color change, as they affect hormonal balance and the overall condition of the body. Therefore, if hair color changes suddenly or is accompanied by other alarming symptoms, it is important to see a doctor for diagnosis and treatment of possible pathologies.
How can you prevent hair color from changing?
Changing hair color can be associated with a number of factors, including genetic predispositions, age-related changes, environmental influences, hormonal changes, and health status. For example, a deficiency of vitamins and minerals, such as iron or B vitamins, can lead to loss of pigmentation. If you notice a sudden or significant change in hair color, especially in combination with other symptoms, such as hair loss or changes on the scalp, it is important to consult a doctor. This will help rule out possible diseases, such as ringworm, hypothyroidism, or other endocrine disorders.
How do stress and lifestyle affect hair color changes?
Stress and lifestyle can have a significant impact on hair color changes. Under the influence of stress, changes occur in the body at the cellular level, including changes in melanin production—the pigment responsible for hair color. An increase in cortisol levels, which is associated with chronic stress, can lead to a loss of pigmentation and, consequently, premature graying. Additionally, bad habits such as poor nutrition, lack of sleep, and absence of physical activity can worsen overall health and hair condition, which can also contribute to changes in their color. Therefore, to maintain the natural color of hair, it is important to lead a healthy lifestyle and manage stress levels.
