Dermatologist: Complete Guide to Skin, Hair, Nail Diseases, Sexual Disease, Diagnosis, Treatment & When to See a Specialist

Dermatology is the branch of medicine concerned with diseases and disorders of the skin, hair and nails. A dermatologist may diagnose conditions through clinical examination and, when necessary, use tests such as skin biopsy, culture, patch testing or dermoscopy. Treatment may involve topical medicines, oral medicines, injections, light therapy, minor procedures or surgery depending on the condition.

What Conditions Does a Dermatologist Treat?

A dermatologist may diagnose and manage a wide range of conditions, including:

• Acne and acne scars
• Eczema and dermatitis
• Psoriasis
• Fungal skin infections
• Bacterial and viral skin infections
• Scabies
• Vitiligo
• Melasma and other pigmentation disorders
• Rosacea
• Hives and allergic skin reactions
• Warts and skin tags
• Moles and other skin lesions
• Excessive sweating
• Hair loss and scalp disorders
• Dandruff and seborrheic dermatitis
• Nail infections and nail disorders
• Skin ulcers and chronic wounds
• Certain autoimmune skin diseases
• Selected skin cancers

Dermatologists can also evaluate skin changes that may sometimes be associated with underlying medical conditions.

When Should You See a Dermatologist?

Consider seeing a dermatologist when you have:

1. Persistent or recurrent skin rashes
2. Severe or persistent acne
3. Unexplained itching
4. New or changing moles
5. Persistent pigmentation or dark patches
6. Hair loss or significant scalp problems
7. Recurrent fungal infections
8. Non-healing wounds or ulcers
9. Changes in the shape, color or texture of a nail
10. A skin condition that does not improve with routine care

A skin problem that appears minor may sometimes require medical evaluation, particularly when it persists, spreads, becomes painful or changes rapidly.

Common Skin Problems Treated by Dermatologists

Acne

Acne can affect teenagers and adults and may cause pimples, blackheads, whiteheads, nodules and cysts. Treatment depends on the type and severity of acne and may include topical medicines, oral medicines or procedures.

Eczema and Dermatitis

Eczema can cause dry, itchy, inflamed or cracked skin. Dermatitis may develop because of irritants, allergies or other causes. Identifying triggers and choosing appropriate treatment are important.

Fungal Infections

Fungal infections may affect the skin, scalp, feet, groin or nails. Because several skin conditions can look similar, a dermatologist may need to examine the affected area or perform testing before selecting treatment.

Psoriasis

Psoriasis is a chronic inflammatory skin condition that can cause thick, scaly patches. It may require long-term management and regular medical follow-up.

Hair Loss

Hair loss can have many causes, including genetic factors, autoimmune conditions, hormonal changes, nutritional issues, illness and stress. A dermatologist can assess the scalp and hair pattern and determine whether further testing is necessary.

Pigmentation Problems

Melasma, post-inflammatory pigmentation and other pigmentary conditions can cause darker or lighter areas of skin. Treatment depends on the underlying cause, skin type and extent of pigmentation.

How Does a Dermatologist Diagnose Skin Diseases?

Diagnosis usually starts with a detailed history and examination of the skin, hair and nails.

Depending on the suspected condition, a dermatologist may use:

• Clinical examination
• Dermoscopy
• Skin biopsy
• Fungal or bacterial culture
• Patch testing for suspected contact allergy
• Wood's lamp examination
• Blood tests when an underlying systemic condition is suspected
• Other specialized investigations when necessary

Not every patient requires laboratory testing. The appropriate investigation depends on the symptoms and clinical findings.

Dermatological Treatments

Treatment varies according to the diagnosis. It may include:

• Creams, ointments, gels or lotions
• Antibiotics for selected bacterial infections
• Antifungal medicines
• Antiviral medicines for selected infections
• Antihistamines
• Steroid medicines when medically appropriate
• Other prescription medicines
• Phototherapy
• Cryotherapy
• Electrosurgery
• Skin biopsy or minor surgical procedures
• Laser or other dermatological procedures where appropriate

Some dermatologists also provide cosmetic dermatology services, but the availability of specific procedures differs between doctors and clinics.

Dermatologist for Hair and Scalp Problems

A dermatologist can evaluate:

• Hair fall
• Excessive hair shedding
• Patchy hair loss
• Male or female pattern hair loss
• Scalp itching
• Dandruff
• Scalp infections
• Alopecia areata
• Scarring hair loss

The cause of hair loss should ideally be identified before starting treatment because different causes require different approaches.

Dermatologist for Nail Problems

Dermatologists also diagnose and treat nail disorders such as:

• Fungal nail infections
• Nail discoloration
• Brittle nails
• Nail separation
• Nail inflammation
• Changes associated with skin diseases

Some nail changes can also be associated with broader medical conditions, so persistent unexplained changes should be assessed.

When Is a Skin Problem Urgent?

Urgent medical evaluation may be appropriate when a skin condition is accompanied by:

• Rapidly spreading rash
• Severe swelling
• Difficulty breathing
• Swelling of the lips or tongue
• Extensive blistering or skin peeling
• High fever with a rapidly worsening rash
• A rapidly changing or bleeding skin lesion
• Severe infection with systemic symptoms

Severe allergic reactions or serious illness require emergency medical care rather than waiting for a routine dermatology appointment.
