Hair diseases constitute an important part of skin diseases. 80-90% of those who complain of hair diseases complain of hair loss.

Among these diseases, there are some genetic diseases, skin diseases such as psoriasis, eczema, and fungus, diseases caused by vitamin and mineral deficiency, diseases that cause hormonal imbalance, some internal diseases such as thyroid disease, and psychological disorders such as depression.

Is Hair Loss a Sign of Other Diseases?


Many factors such as eating habits, stress, using the wrong product, and various diseases can cause hair loss and affect the person negatively. So do you know what symptoms of hair loss are? Hair loss is usually genetic, but it can also be experienced due to various diseases. In addition, while temporary diseases, sinusitis, infection, intestinal parasites trigger hair loss, B12, magnesium, zinc, and iron deficiency can also lead to hair loss. Here are the diseases that can cause hair loss:

  • Genetic diseases

The causes are different in women and men. The type seen in men is the masculine type, which is seen in more than 50% of the genetic population, which is a hormone-sensitive hair loss, which is also chronic. As the age advances, hairlessness creates and may require hair transplantation, therefore. Fortification medicines, mesotherapy, and PRP treatment, which are begun at an early age, hinder the shedding speed. It prolongs the time to go to baldness.



Nowadays, male pattern hair loss with the age of 16-18 is more common in young girls. Reasons for this disease are too much stress, bad eating habits, long periods of fasting, and hormonal issues.

  • Skin diseases

Apart from major genetic spills, skin and internal diseases also cause hair loss. Many of the skin-related hair loss problems occur when the skin condition affects the scalp. Hair loss and balding might be inescapable if the hair is influenced by diseases like psoriasis, dermatitis, skin inflammation, lichen illness, unreasonably slick skin, contagious infections. The treatment of these spills is conceivable with the treatment of the fundamental skin illness.

  • Nutritional problems

Hair loss because of bad eating habits is another basic factor. Not eating a standard and adjusted eating regimen, long haul hunger, a uniform eating routine, and devouring nourishments high in sugars can at last effect and shed the hair. Its treatment is very functional and it is essential to begin a decent eating regimen.

  • Vitamin and mineral deficiency

Although there is no nutritional problem, the lack of vitamins and minerals in the blood is another reason for hair loss. On the off chance that our nutrients and minerals, for example, B12, nutrient D, folic corrosive, biotin, zinc, iron are low, hair can’t be supported and drops out. In any event, when there is no iron inadequacy, iron supplementation diminishes going bald. In these cases, the support of the lack must be adjusted by reaching a doctor.

  • Hormonal diseases

On the off chance that the individual has hormonal issues, menstrual postponements or anomalies, expanded hair development, unnecessary skin problems, and quickened weight gain, and when going bald is added to these symptoms, at that point hormonal hair loss can be referenced. The dermatologist ought to be counseled to decide the reason for these issues with a blood test on the second or third day of the period.



  • Some internal diseases and drug use

Several internal diseases and the medication to treat them are some of the other causes of hair loss. This circumstance must be completely explored by assessments and tests by expert specialists. If a sudden hair loss has begun, surgeries, febrile diseases, drug toxicities, blood loss, severe trauma may be among the reasons to be considered.

  • Birth and chemotherapy process

Aside from all these, there are two explicit reasons for going bald. One is postpartum hair loss which begins 2-3 months after the birth. Another is hair loss in patients receiving chemotherapy. This hair loss is more uncommon with the utilization of more present-day drugs lately, yet it is a circumstance that will in general recuperate suddenly when the treatment is finished.

  • Cosmetic factors

Tying the hair tight, inner bonnets, blow-drying processes exposed to excessive heat, dyes used to lighten the hair color, bleachers, straightening methods cause hair loss by damaging the hair from the outside. For this situation, the main treatment is to keep the hair from being affected by these applications. Applying the essential support and care measures for hair will give the ideal look.

  • Stress and depression

Experiencing too much stress is another explanation behind going bald just like any sickness. Psychiatric disorders and the medications utilized in their treatment can influence the hair and cause it to drop out. Hair is a living organ that can be influenced by numerous variables in the day by day life in a brief timeframe. When something turns out badly in the individual’s life, the individual should initially gauge himself in the light of this data and afterward look for help from a dermatologist if it is important.



This is because misguided and hearsay information from the environment can cause patients to lose time. If there is an important underlying cause, it may be delayed in diagnosis and treatment. Also, facial masks applied unknowingly with the opinion of ​​preventing balding, and regrowing hair can make irreversible harm by actually causing more harm.

Diseases Where Hair Loss Is a Symptom


Hair has been a symbol of beauty and health in all cultures throughout human history. For this reason, when the hair starts to fall out, almost everyone starts to worry. Incorrect care is the most common cause of hair loss, and when this habit is abandoned, it is possible to regain lush hair as before. However, hair loss can also be a sign of important diseases such as hair shaft and scalp diseases, thyroid or anemia.

That’s why hair loss should not be taken lightly. Hair has a routine shedding pattern and 50-100 hair loss per day is considered natural. However, when the shedding exceeds this number, 4-5 or more hair strands come to the hand with a slight pull of the hair, or when the thinning noticed in the forehead and top areas begins, it is necessary to consult a specialist.



  • Hereditary hair loss (Androgenetic alopecia)

It is stated that genetic predisposition and androgen hormones (in men), especially dihydrotestosterone, play a role in this hair loss. In hereditary hair loss, in men, the hairline on the forehead recedes backward and the scalp becomes thinner by opening from the top of the scalp. In women, thinning and thinning are observed in the scalp, especially in the hair from the top to the periphery, without opening in the forehead line.

By using medicines in the form of tablets, sprays and solutions, and some supportive dermo-cosmetic products, the hair loss process can be delayed and the unaffected hair can be partially protected. In cases where the hair is completely lost and permanent baldness occurs, hair transplantation is a good treatment method for suitable people.

  • Wrong diets

Especially improperly made unbalanced diets and eating poor in protein can cause hair weakness, increase in fractures, and hair loss. In order for the keratin substance, which is the structure of the hair, to be synthesized in the body, some basic proteins must be taken into the body in sufficient quantities through nutrients. When the amount of protein needed by the body is not taken, hair loss begins.

  • Fungal diseases

Although fungal diseases involving the scalp are generally seen in children, it can also cause hair loss in adults and permanent baldness can occur if not treated.

  • Some medications

Experts add that some drugs have side effects such as hair loss: “Some drugs used for blood thinners, arthritis, gout, depression, heart diseases, and high blood pressure can shed hair. In addition, hair loss can be observed when the use of birth control drugs is discontinued.”

  • Alopecia Areata (Ringworm disease)

Alopecia areata, an autoimmune disease, popularly known as ringworm disease, occurs, especially in severely stressful situations. In the scalp, in some patients, all body hair including eyebrows, eyelashes, and beards cause oval-shaped hair loss due to some autoantibodies produced by the body. Although factors such as genetic predisposition, neurological factors, infections, and stress are thought to trigger the disease, the underlying factor has not yet been fully elucidated. If this disease, which does not cause permanent baldness, lasts for a long time, treatment may be required.

  • Severe stressful situations

Hair loss is common in severely stressful situations. Stress causes the secretion of various stress hormones in our body, leading to the deterioration of internal balance and the emergence of many diseases as a result. These diseases can also shed hair.



  • Excessive weight loss

Hair loss is a situation that often develops after excessive weight loss. The reason for this is that in excessive weight loss, the rate of hair in the natural shedding phase called telogen effluvia and the lengthening of the shedding time. Hair loss can continue for an average of 3-6 months and then stop.

  • High doses of vitamin A

Taking high doses of vitamin A can also result in intense hair loss. Hair loss ends after vitamin A intake is stopped.

  • Anorexia and bulimia

Hair loss is frequently encountered in patients with eating disorders such as anorexia and bulimia due to the deficiency of elements such as iron, vitamins, protein, and zinc. When these diseases are treated, hair loss stops, and the lost hair is restored.

  • Systemic diseases

Experts point out that more than 30 systemic diseases can shed hair and say, “The underlying factor is usually thyroid diseases and anemia.” Intense hair loss can be observed after severe surgical procedures, high fever diseases, severe infectious diseases, and sometimes a severe flu infection. Experts state that hair loss can stop after these diseases are detected and treatment is started.

  • Hormonal changes

Another cause of hair loss is hormonal changes. Hair loss observed especially after birth occurs when the pregnancy hormone is replaced by the estrogen hormone. Intense hair loss for a few months is considered normal. However, when it takes a long time, it is necessary to consult dermatologists. In addition, hair loss problems may develop with menopause. Although hair loss stops after a while, the density of hair may not reach its pre-menopausal density.

  • Iron deficiency

Iron deficiency is among the main responsible for hair loss. Hair loss is very common in patients who do not get enough iron with diet or have problems with the absorption of iron.



  • Cicatricial Alopecia

It develops as permanent baldness, it can be localized or widespread in a certain area of ​​the scalp. In this disease, permanent damage occurs in the hair follicles. It is of great importance that dermatology specialists start treatment before the disease progresses since it is not possible to regrow hair in the places of the shed hair.

  • Watch out for wrong hair care!

The underlying factor of hair loss can also be daily faulty hair care practices.

  • Shampooing the hair too much

Dyeing hair too often, styling the hair with some methods such as straightening and applying hot blow-dry can cause hair breakage.

  • Combing when hair is wet

Since its elasticity increases when wet, hair can be easily damaged. For this reason, combing and brushing the hair with too many comb strokes, especially when wet, can cause hair breakage.

  • Make a ponytail

Pulling the hair very tightly and making a ponytail with rubber can pull the forehead line of the hair back and cause hair loss, which is called tractional alopecia. Likewise, tight and stretched braids and hair added with small clips can damage the hair follicles with the force of pulling.

Hair, which is an integral part of our beauty, begins to fall out more, especially in seasonal transitions. Almost all of us are avoiding this problem by saying “it is seasonal”. However, it is beneficial not to let go of caution. Experts warn that increasing hair loss, especially longer than a month, might be the harbinger of some diseases.

For this reason, a dermatologist should be consulted in case of hair loss that lasts more than 100 strands per day, lasting longer than a month, or focal loss in the form of money in the hair or pimples on the scalp, because when the treatment is late, hair loss can progress. Experts say that existing hair follicles go through 3 periods, called growth, regression, and rest periods, to form new hair. 90-95 percent of our hair is in the growth phase. The growth period of the hairs on the scalp varies between 1-7 years.



Hair growth depends on the climate, age, nutrition, and hormonal factors as well as genetic factors. At the end of the growing period, the hairs begin to regress and this process takes about 2 weeks. This is followed by a rest period of about 3 months. At the end of this period, the hair in the new growth period is formed. The hair in the resting period can fall out during processes such as washing and combing. Since 5-10 percent of the scalp hair is in the resting period, up to 100 hair loss per day is considered normal.

Tractional alopecia occurs due to excessive stretching of the hair while shaping or collecting. Hair becomes sparse, especially in areas with high stretching. For this reason, the hair should not be overstretched while it is being collected. Alopecia areata, popularly called “ringworm”, usually starts with round or oval money-shaped spills in any part of the scalp. The disease can also result in the complete loss of hair, eyebrows, or body hair. It can occur with atopic disease, thyroid diseases, and other autoimmune diseases, as can be seen in completely healthy people.

In women, unlike men, the hairline on the forehead is preserved, and the thinning at the top is more pronounced. In this type of hair loss, gradual thinning is observed in the hair over the years. Although genetic factors play a large role, they can also be associated with hormonal disorders in women. The type of hair loss is understood by the dermatologist after clinical examination. Some tests can be performed to determine the diseases that may cause or accompany hair loss.



Depending on the type of hair loss, different treatment options such as local treatments to the scalp or injections to the spilled area, systemic treatments for the underlying cause, or ultraviolet light treatments are applied. In recent years, some substances obtained from the patient’s own blood have also been tried in treatment. Specialists who pointed out that patients with hair loss should definitely consult a physician, warn us: “Because attempting to treat hair loss by non-physicians or by hearing information may result in permanent damage to the hair follicles, the hair may never grow in patients again.” warns.
