How to Get Rid of Seborrheic Dermatitis

Seborrheic Dermatitis: Severe Dandruff with eczematization
Seborrheic Dermatitis: Severe Dandr

We have already seen the causes and triggers of Seborrheic dermatitis. Now let us examine ways on how to get rid of seborrheic dermatitis.

How to treat Seborrheic Dermatitis?

Principles of management
  • Patient education is important:
  • No Cure, can only be controlled.  Like dental care: need daily attention.
  • Regular Washing of scalp
  • Anti seborrhoeic treatment alternating with normal shampooing
  •  Hair tonics & tinctures with alcohol base: Aggravate
  •  Normal Soap & Shaving Creams: Use emollients and emollient soap substitutes
  • Alter Food Habits: low fat, low sugar diet ;cut down on the alcohol.
  •  Manage Stress
Regulation of Hyperseborrhea
  • Control Of Dietary Habits
  • Stress Management 
  • Regular Washing without causing irritation
  • Avoidance of offending drug, alcohol
  • Usage of creams containing antiseborrhoeic agents: Zinc Acetyl Methionate,  Undecylenic Acid Derivatives
  • Other antifungal creams and solutions to control Malassezia
Removal Of Thick Scales
  • —Overnight application of tar/urea/salicylic acid containing creams 
  • Rubbing with warm mineral oil and  washing off
  • If crusting and oozing: A course of antibiotic with a steroid-antifungal cream for 5-7 days;once scales and 2ry infection is cleared; start antimalassezia treatment.
SEVERE/ UNRESPONSIVE CASES
  • —1- 2 Weeks’ course of systemic antiyeast treatment with Ketoconazole,Itraconazole or Fluconazole
  • Class IV or lower strength topical steroid creams, lotions or solutions for acute flares for 5-7 days only.
  • Continue with anti seborrhoeic/ antiyeast measures
  • Other alternatives: Calcineurin derivatives Pimecrolimus/tacrolimus, metronidazole gel, Narrow band UVB therapy etc. 
  • A course of low dose Isotretinoin may help some patients
Treating the acute phase
  • Antifungal treatments remove the Malassezia yeasts, and this is followed by improvement in the inflamed lesions.Relapse after antifungal treatment is common, but is delayed until re-colonisation has occurred.
  • The most important component of any treatment is frequent shampooing. This will stop the sebum from accumulating and the seborrhoeic dermatitis will be controlled. Commercially available products such as Nizoral 2% or Selsun ‘Yellow’ will assist in controlling this condition.
  • Changing your diet also helps this condition. Sufferers should eat a low fat, low sugar diet and cut down on the alcohol.
  • Topical steroid lotions for severe cases is often indicated. Tar products which were once a mainstay, are gradually being replaced by “cosmetic” products and of which new and even more effective treatment modalities, are now in development.
  • Modern shampoos incorporating antidandruff ingredients such as ZPT and imidazoles can effectively eliminate the clinical condition of seborrheic dermatitis to an extent that dermatologists would envy in other therapeutic areas .
  • Topical corticosteroids may hasten recurrences, may foster dependence because of a rebound effect, and are discouraged except for short-term use. Skin involvement responds to ketoconazole, naftifine, or ciclopirox creams and gels. Alternatives include calcineurin inhibitors (ie, pimecrolimus, tacrolimus), sulfur combinations, or propylene glycol. Class IV or lower corticosteroid creams, lotions, or solutions can be used for acute flares. Systemic ketoconazole or fluconazole may help if seborrheic dermatitis is severe or unresponsive.
  • Dandruff responds to more frequent shampooing or a longer period of lathering. Use of hair spray or hair pomades should be stopped. Shampoos containing salicylic acid, tar, selenium, sulfur, or zinc are effective and may be used in an alternating schedule.  Selenium sulfide (2.5%), ketoconazole, and ciclopirox shampoos may help by reducing Malassezia yeast scalp reservoirs. 
  • Seborrheic blepharitis may respond to gentle cleaning of eyelashes with baby shampoo and cotton applicators. The use of ketoconazole cream in this anatomical region is controversial.
What is the Prognosis of Seborrheic Dermatitis?
Infantile Seborrheic dermatitis or cradle cap.
Infantile Seborrheic dermatitis or cradle cap.
  • Infantile seborrheic dermatitis: spontaneous resolution may occur within a few weeks or it may persist for several months, but in most cases resolves by 8 months of age.
  • Adult seborrheic dermatitis: usually lasts for years to decades, with periods of improvement in warmer seasons and periods of exacerbation in colder months.

What is Seborrheic Dermatitis?

The cause, triggers and complications of the dermatitis of the sebaceous areas

Seborrheic dermatitis, the dermatitis of the sebaceous areas, is a common disease. It may be considered part of a clinical spectrum which include dandruff and psoriasis..

The Clinical Spectrum of Seborrheic Dermatitis

Seborrheic dermatitis is a common skin disease associated with increased and altered sebum production and yeast colonization.  Seborrheic dermatitis presents as a chronic dermatitis in sebum rich areas of the body like scalp, face and upper trunk. Its milder, non-inflammatory form is known as dandruff.  Seborrheic Dermatitis affects 1-3% general population, though dandruff is a very common occurrence. More than 36% of HIV positive patients have Seborrheic Dermatitis.

What is the cause for Seborrheic Dermatitis?

Seborrheic dermatitis appears in genetically pre-disposed individuals with the so called seborrheic diathesis, meaning increased sebum secretion  in the sebaceous gland rich areas of the body-  the scalp, face, front of chest, and in between the shoulder blades.  Certain triggering agents plus the greasiness of the skin in these areas is a flourishing ground for the yeasts known as malassezia. These yeasts breakdown and alter the composition of the sebum which further sets in motion an inflammatory response in the skin. This again increases the sebum secretion and the cycle continues.

The skin becomes red, irritated and scaly. Itching is prominent in acute, active state. In addition to the classical sites, seborrheic dermatitis can also affect the eyelids, armpits, groin and gluteal fold.

Seborrheic Dermatitis can cause an intensely itchy scalp.
Seborrheic dermatitis is a cause for severe itchy scalp.

Malassezia species M.restricta and M.globosa have been isolated from the seborrheic dermatitis skin.

Seborrheic dermatitis is seen in the first  few months of life when maternal androgens are present in the blood. Then, the disease re appears in susceptible individuals after the sebaceous glands become active during puberty.

Seborrheic dermatitis can be considered a part of the clinical spectrum between dandruff and psoriasis. (See the Figure above)

What are the triggers for Seborrheic Dermatitis?

  1. Stress & Fatigue. Both lowered immunity and hormonal stimulation are the reasons for increased seborrheic dermatitis in stressed and fatigued conditions.
  2. Hormonal  Triggers . Androgen hormones control the sebaceous activity in humans. Probably these are under the control of a sebotrophic hormone secreted from the hypothalamus. Body builders using anabolic steroids get severe attacks of seborrheic dermatitis.
  3. Environmental Triggers. Seborrheic dermatitis is precipitated in low humid conditions and in winter.
  4. Low Immune states. Either due to medications, or diseases like HIV and malignancies trigger seborrheic dermatitis.
  5. Food. Sugar consumption, fast foods, Vit B including B12 malutilization, biotin deficiency, niacin deficiency, pyridoxine deficiency, zinc deficiency and excess alcohol consumption have all been found to increase the incidence of seborrheic dermatitis .
  6. Drugs. Broad spectrum Antibiotics, OCP, Systemic Steroids, buspirone, chlorpromazine, cimetidine, ethionamide, griseofulvin, haloperidol, interferon alfa, lithium, methoxsalen, methyldopa, phenothiazines, psoralens, stanozolol are some of the medications that have been found to increase seborrheic dermatitis. The list is not complete.
  7. Diseases. Seborrheic dermatitis may be the presenting feature of Parkinsonism and  HIV infection. Incidence of seborrheic dermatitis is high in epilepsy, idiopathic post encephalitis,  diabetes mellitus, paralytic states etc.

What are the other causes for Itchy Scalp?

Seborrheic dermatitis has to be differentiated from other causes of itchy scalp, like scalp  dryness, contact allergy and psoriasis, all of which cause itchy and scaly scalp. For details see Causes of Itchy Scalp.

What are the types of Seborrheic Dermatitis?

  1. Infantile Seborrheic Dermatitis
    1. Cradle cap
    2. Trunk: Flexural, napkin area
    3. Leiner’s disease
  2. Adult Seborrheic Dermatitis
    1. Scalp: Dandruff and inflammatory types.
    2. Face: Inflammatory and non inflammatory, with blepharitis(eye lid)
    3. Trunk: Petaloid, pityriasiform, follicular, follicular, eczematous type
    4. Generalized exfoliative erythroderma

What are the complications of Seborrheic Dermatitis?

  • Psychosocial impact: Chronic visible disease may affect a person’s self esteem.
  • Secondary bacterial infection with Staphylococcus aureus may occur, with typical impetigo with increased redness, oozing, and crusting.

What is Leiner’s Disease?

Leiner’s disease is a complication of seborrheic dermatitis in infants with C5 complement deficiency. There is usually a sudden confluence of lesions leading to a generalised scaling and redness of the skin. The child is severely ill with anemia, diarrhea, and vomiting. Secondary bacterial infection is common.

Because of the varied internal causes, it is quite difficult to get rid of seborrheic dermatitis. But, with some life style changes and appropriate treatment,  it is possible to get rid of Seborrheic Dermatitis.
