seborrheic dermatitis

seborrheic dermatitis
Chronic inflammatory and eczema skin diseases

What is seborrheic dermatitis?


In the skin, sebum is secreted from the sebaceous glands at the root of pores to form a sebum film that brings moisture to the skin surface.​ It is called. Seborrheic dermatitis is a condition caused by the decomposition of sebum into free fatty acids by ultraviolet rays or fungi (fungi) based on the seborrhea. In other words, seborrheic dermatitis is a chronic inflammatory and eczema skin disease that can lead to hair loss and damage to the hair roots because the pores are clogged or inflamed due to the active secretion of the sebaceous glands of the scalp.​ Literally, the scalp is inflamed.


Causes of seborrheic dermatitis


The causes of increased hair loss may vary from person to person, but in most cases, various causes can be considered, such as constitutional relationships, the influence of lifestyle/eating habits, and stress.


excessive sebum secretion

metabolic abnormalities


life pattern

Frequent drinking, short sleep


immune dysfunction

autoimmune disease



Autonomic nervous system and hormonal imbalance


oily eating habits

malnutrition, vitamin B deficiency


sudden temperature change

Hormonal and immune status changes

1) Excessive sebum secretion

If there is a problem with the metabolism, the secretion of sebum increases, which can cause seborrheic dermatitis.

2) If there is an abnormality in immune function

The risk of developing seborrheic dermatitis increases when there is an abnormality in immune function such as an autoimmune disease. For example, if you have or have rheumatoid arthritis, asthma, Crohn's disease, ulcerative colitis, atopic dermatitis, psoriasis, or uveitis, your risk is much higher than if you didn't.

3) Oily eating habits

Irritating and oily eating habitsMalnutrition, vitamin B deficiency can cause abnormalities in metabolism

4) There is a cause closely related to the lifestyle

People who drink frequently, have a short sleep period, or have poor sleep quality may have decreased growth hormone secretion. Growth hormone is related to many aspects, such as aging and antioxidants, not only in growing infants and adolescents, but also in adults who have completed growth. And growth hormone is a hormone necessary for the metabolism of the scalp, and it is mainly secreted from 10:00 to 02:00 at night, so it is good to enjoy a good night's sleep at this time. Of course, if you do not have a normal sleep pattern due to the nature of your work or study, hormonal balance can be disrupted, which can lead to hair loss.

5) stress

Like stress, which is the root of all diseases, excessive stress disrupts the balance of the autonomic nervous system and affects hormonal balance. Increased oiliness on the scalp due to an increase in male hormones related to sebum secretion and cortisol, a stress hormonedo. In addition, it is related to poor blood flow to the scalp and insufficient nutrient supply to the hair follicles due to constriction of blood vessels. Working from early in the morning until late at night, or being chased by childcare, may become overstressed.

6) Seasonal environmental factors

Symptoms worsen due to changes in hormones and immune status due to sudden changes in daily temperature in spring, autumn and winter, and rapid changes in sunlight.

Symptoms of seborrheic dermatitis


Scalp abnormalities due to inflammation


If it comes with folliculitis


hair loss pattern
In case of circular hair loss

1) Scalp abnormalities due to inflammation

Repeated inflammation can cause itching, redness, large-variety of dandruff (white, yellow, red), oozing, etc.

2) If it comes with folliculitis

Since it is common to come along with folliculitis, severe skin damage can cause oozing and pus, which can lead to thinning of the hair in the area and hair loss as the number of hairs decreases.

3) If the pattern of hair loss appears to be circular hair loss

It appears to be circular baldness. In other words, it is easy to be mistaken for alopecia areata because the scalp inflammation becomes severe and folliculitis occurs, and severe and extensive folliculitis causes round bald spots like alopecia areata.

Features of seborrheic dermatitis


chance of recurrence

Incorrect management or your own condition


Scalp that can thicken

Due to repeated improvement and exacerbation


Psoriasis and other diseases

Diseases with different treatment methods


Can develop into folliculitis

May cause permanent hair loss

1) Excessive sebum secretion

If there is a problem with the metabolism, the secretion of sebum increases, which can cause seborrheic dermatitis.

2) There is a high possibility of recurrence

It may improve naturally, but it is famous as a chronic disease that repeats improvement and worsening depending on poor management or one's condition. It is important to receive treatment for a full cure and to improve fundamental immunity to prevent recurrence.

3) It can thicken the scalp

Repeated and chronic remissions and exacerbations can lead to thickening of the scalp.

4) Easy to confuse with psoriasis

Dry scalp and seborrheic dermatitis are diseases with slightly different prognosis and treatment methods.

5) Possible to develop into folliculitis

If seborrheic dermatitis is severe, it can develop into folliculitis and cause permanent hair loss.

Accurate inspection required


Seborrheic dermatitis is a disease that is notorious for being difficult to cure once it occurs. The causes of seborrheic dermatitis are complex, ranging from diet and lifestyle to other diseases. In addition, there may be constitutional factors, so it is important to systematically diagnose and accurately analyze the cause of the disease. It is not an exaggeration to say that identifying the cause from various angles determines the treatment direction and treatment effect.


blood test

liver, kidneys, thyroid, cholesterol,

Anemia level, etc.


hormones, essential minerals,
​ heavy metal inspection

Immune imbalance check


other diseases,
​ Determination of bodily dysfunction

Immune function problem identification


Determination of heredity

Identify some genetic factors

1) blood test

It checks the liver, kidney, thyroid, cholesterol, anemia levels, etc. to check the disease.

2) Hormone, essential minerals, heavy metal test

Factors that can cause immune imbalance are checked in advance. It is a test to improve and prevent diseases and promote health through the evaluation of nutritional imbalances in the body, heavy metal contamination and endocrine function, and based on the results, clinical nutrition and medical prescriptions tailored to each individual.

3) Identification of other diseases or deterioration of bodily functions

When the adrenal function is lowered, the immune function is lowered, which can lead to exacerbation of scalp inflammation.

4) Determination of heredity

There may also be some genetic factors.

Requires a wealth of experience from medical staff


In case of a misdiagnosis, the treatment time is missed and symptoms are aggravated, and as a temporary palliative treatment, chronic scalp inflammation and folliculitis are exacerbated.

Severe folliculitis cannot be treated with steroids and antibiotics, and an incision and drainage operation is absolutely necessary.

A complete cure is possible only when the patient's lifestyle, sleep pattern, and diet are checked.


Accurate hair loss diagnosis


Based on the experience of performing hair loss treatment and hair transplantation for over 10 years, we have researched only hair.


honest care


We do not recommend treatment to patients who do not need treatment.

Treatment is decided by prognostic diagnosis, and those with a high probability of natural healing are not treated immediately, but only observed.

We propose an appropriate hair loss treatment plan in consideration of the patient's scalp condition and hair loss progress


The main cause of poor prognosis of scalp inflammation

  1. frequent relapse

  2. If the range is wide

  3. If the period is old

  4. Long-term use of steroids or antibiotics

  5. In case of severe folliculitis that is filled with pus

  6. In case of hair loss

  7. Habitual frequent drinking and smoking

  8. Genetic factors (autoimmune diseases, etc.)

What is a THL test?

The THL (Total Hair Loss) test is a systematic hair loss diagnosis test at Mori Clinic. It consists of four essential tests (scalp diagnosis and basic test, hair growth rate test, blood test, hair tissue heavy metal test) and five optional tests (cell membrane penetration). test, saliva/hormonal test, muscle type test, free radical test, biofunction/lifestyle test).

suitable treatment


It is the most commonly used medicine for alopecia areata or seborrheic dermatitis.



  • relatively cheap

  • Easy to handle, quick to use, and widely used


  • Side effects can be severe

  • Scalp depression, scalp inflammation, aggravation of circular hair loss, recurrence, etc.

  • For long-term treatment such as oral medications and injections, hypertension, diabetes, osteoporosis, obesity, depression, gastritis, gastric ulcer, etc.

  • Short-term use is fine, but symptoms worsen as the period of use increases and the intensity increases.

Immunotherapy and nutritional therapy are treatments that induce fundamental improvement by reducing side effects in the treatment of alopecia areata or seborrheic dermatitis.



  • few side effects

  • not good at relapse

  • It is not harmful to the body, but rather improves overall immunity

  • In some cases, treatment progresses significantly faster than steroids.


  • relatively high price

  • There may be temporary swelling and itching

Mori's treatment


At Mori Clinic, we are treating hair loss and dermatitis without using steroids.


immunization treatment

Non-steroidal immunocomplexes

Fundamental improvement treatment with no harm to the human body


immunization treatment

Fluid treatment supplied after identifying deficient components through hair component test

Nucleic acid, growth factor, vitamin, mineral, amino acid, liver detoxification, vitamin effect amplifying substance


regenerative light therapy

compound wavelength

Treatment to help improve and regenerate the scalp

1) Vaccination treatment

Treatment that relieves symptoms such as superficial keratin, sebum, and inflammation is temporary, so recurrence is frequent. It is necessary to correct the underlying immune problem that causes scalp inflammation. It corrects the patient's overall immunity by replenishing deficient minerals, correcting hormonal balance, and combining nutritional therapy.

It is a treatment method that uses immune complex substances (nucleic acids, growth factors, vitamins, minerals, amino acids, etc.), not steroids, without any harm to the human body and fundamentally improves the scalp. You can expect the effect of restoring basic health by removing scalp inflammation and improving immunity by administering it into the body.  It is also effective in improving atopy and skin eczema.


2) Immunotrophic treatment

In order to improve the resolution of nutritional imbalance, the treatment effect can be further doubled if the damaged hair follicles are repaired through nutritional treatment, and the exact condition is identified through the hair component test and then improved. Fluid therapy is a personalized treatment that combines nucleic acids, growth factors, vitamins, minerals, amino acids, liver detoxification, and vitamin effect amplification substances.  It is a method to normalize immunity by not using steroids to lower immunity, suppressing IL-1 and TNF-a, which are representative inflammatory substances in the human body, and balancing hormones such as cortisol.

3) Regenerative light treatment

It is a treatment that strengthens weakened hair follicles and helps improve and regenerate the scalp by irradiating the entire scalp with a complex wavelength as a principle.
