At IA Dermatology in Harley Street, London, our Consultant Dermatologists provide expert medical assessments to diagnose the root cause of your scalp diseases and implement evidence-based treatment plans.

We regularly treat:

• Scalp dermatitis
• Seborrhoeic dermatitis (dandruff-related inflammation)
• Scalp eczema
• Scalp psoriasis
• Dry scalp and barrier dysfunction
• Allergic and contact scalp reactions
• Sun damage affecting the scalp
• Scalp cysts and benign lesions
• Scalp mole assessment and monitoring

Understanding Common Scalp Medical Conditions

The scalp is a unique environment with a high density of hair follicles and sebaceous (oil) glands. This makes it susceptible to specific skin conditions on the scalp that do not appear elsewhere on the body.

1. Scalp Dermatitis and Seborrhoeic Dermatitis:
   Often manifesting as “stubborn dandruff,” seborrhoeic dermatitis is caused by an overgrowth of yeast (Malassezia). This can lead to a red scalp and dandruff, itchy red patches, and in severe cases, yellow scabs on the scalp. While many associate this with infants, cradle cap in adults is a frequent diagnosis in our clinic, requiring prescription-strength anti-inflammatory and antifungal care.
2. Scalp Psoriasis and Eczema:
   These chronic inflammatory conditions often present as white scaly patches on the scalp or dryness patches on the scalp. Unlike standard dandruff, scalp psoriasis can feel thick and “plaque-like,” while scalp eczema often leads to a compromised skin barrier, resulting in a burning scalp and extreme sensitivity. If you are experiencing eczema or psoriasis in London, professional intervention is required to prevent the inflammation from damaging hair follicles.
3. Scalp Folliculitis and Infections:
   If you notice small red bumps on the scalp or itchy scalp red bumps that resemble pimples, you may be suffering from scalp folliculitis. This is an inflammation of the hair follicles caused by bacteria or yeast. Without treatment, these red bumps on the scalp can become painful, lead to scalp sores, and eventually cause localized scarring hair loss (alopecia).

The Link Between Scalp Inflammation and Hair Loss

One of the most frequent questions we hear is: “Does itchy scalp mean balding?” or “Can scalp eczema cause hair loss?”

The answer is complex. While a temporary hair shedding event is common during a flare-up of scalp inflammation, chronic untreated conditions can lead to more permanent issues. Red scalp and hair loss together often indicate that the “soil” (the scalp) is too inflamed to support the “plant” (the hair).

Conditions like female patterned hair loss can be worsened by a poor scalp environment. By addressing scalp problems early, we can often halt the progression of thinning hair and restore the health of the hair cycle.

Every consultation is personalised, medically led, and designed to restore scalp health while supporting long-term hair and skin integrity.

What is DEXA CO₂ Laser CoolPeel®?

The DEXA CO₂ Laser CoolPeel® is an advanced fractional CO₂ laser that resurfaces the skin in a precise and controlled way. Unlike traditional CO₂ lasers, it delivers short bursts of energy at very low heat. This allows effective skin rejuvenation with minimal downtime and a lower risk of side effects.

What Does It Treat?

The treatment is designed to improve skin texture and promote collagen production. It may be recommended for:

• Acne scars and other types of scarring
• Fine lines and wrinkles skin pigmentation disorders.
• Sun damage and pigmentation
• Enlarged pores
• Overall skin rejuvenation and tightening

How Does It Work?

• The laser creates thousands of tiny micro-injuries in the skin’s surface.
• This stimulates the body’s natural healing response and triggers new collagen and elastin production.
• Smoothes the skin surface—similar to the results seen with Dermapen microneedling, but with the added power of thermal energy.

Because the treatment delivers energy in short pulses with minimal heat, it is more comfortable than traditional CO₂ resurfacing and requires less downtime.

What to Expect During and After Treatment

Most patients describe a warm, prickling sensation during treatment. A topical anaesthetic cream is usually applied beforehand to make the procedure more comfortable.

The treatment usually lasts 15–30 minutes, depending on the area being treated. After treatment, the skin may look red, similar to mild sunburn, for 1–2 days.This is much faster healing compared to minor dermatologic surgery.

Mild dryness, tightness, or rough texture can occur as the skin heals.

Some patients experience light peeling or flaking for a few days. Makeup can usually be worn after 24 hours, unless advised otherwise. Full results develop gradually over several weeks as new collagen is produced.

For patients looking for even faster healing and “glow” results, we often suggest Polynucleotides or Exosome therapy to accelerate tissue repair.

Treatment Plan and Aftercare

For best results, a course of 3–4 treatments spaced 4–6 weeks apart is usually recommended.
Some patients notice improvement after a single session, especially for skin texture and radiance.

1. Avoid direct sun exposure and wear a broad-spectrum SPF 30–50 daily.
   
2. Avoid saunas, hot showers, and vigorous exercise for 24–48 hours.
   
3. Use a gentle cleanser and hydrating moisturiser until redness subsides.
   
4. Do not pick, scratch, or exfoliate the skin while healing.
   

Risks and Suitability

DEXA CO₂ CoolPeel® is considered safe when performed by trained professionals. Possible temporary side effects include redness and mild swelling, skin dryness or flaking, and sensitivity to sunlight. Rare side effects include prolonged redness, infection, or pigmentation changes. Most skin types can be treated, but it may not be suitable if you are pregnant, breastfeeding, have active infections, or certain skin conditions.If you’re in London and looking for expert skin rejuvenation, book a consultation at IADermatology on Harley Street today.

CoolPeel® vs. Traditional CO₂ Laser: What’s the Difference?

Many patients are hesitant about CO₂ lasers because of the “social downtime”—often requiring 7–14 days of recovery. Traditional CO₂ lasers deliver heat in a way that damages the top layer of skin to reach the layers beneath.
The DEXA CO₂ CoolPeel® is different. It uses a proprietary “H-Pulse“—a high-peak-power, short-pulse delivery that targets the superficial layer of skin tissue without causing thermal damage to the surrounding area. This means you get the dramatic skin-resurfacing benefits of a CO₂ laser but without the crusting, peeling, or long recovery times.

Why Choose Harley Street for Your Laser Resurfacing?

Harley Street is globally recognised as the pinnacle of medical excellence. Choosing IADermatology for your dexa laser treatment ensures you are in the hands of specialists who understand the complexities of skin anatomy.
Unlike high-street salons, a clinical environment allows us to combine medical-grade technology with a bespoke dermatological approach. We don’t just “fire a laser”; we assess your skin’s health, your hormonal profile (especially if you are experiencing hair change during menopause or PCOS-related skin issues), and create a plan that supports long-term skin integrity.

The Perfect Candidates for DEXA CO₂ Treatment

This treatment is ideal for anyone looking to “refresh” their skin without surgery. It is particularly effective for:

• The “Pre-juvenation” Patient: Younger patients (20s-30s) looking to prevent fine lines and keep pores tight.
• The Scarring Patient: Those with lingering textures from hormonal acne.
• The Busy Professional: Since it is a “cool” laser, you can return to work in London almost immediately, making it a popular “Friday afternoon” procedure.

Our consultant dermatologists perform comprehensive skin examinations to identify moles, track changes over time, and provide a vital melanoma check before signs become clinically obvious. This proactive, preventative approach offers patients clarity, reassurance, and long-term skin health monitoring.

This proactive, preventative approach offers patients clarity, reassurance, and long-term skin health monitoring.

Why is a Professional Skin Map Necessary?

Mapping moles allows us to digitally record and compare your skin’s evolution over time. This process helps distinguish harmless spots from pigmented lesions that require further investigation. This is particularly valuable for patients wondering what moles should I get checked, especially those with:

• A high count (over 50 moles).
• A personal or family history of skin cancer.
• Fair skin, red hair, or a history of severe sunburns.
• Atypical or irregular-looking moles.

Every assessment is performed by a senior consultant dermatologist, ensuring clinical judgment guides every decision. If a lesion is found to be suspicious, it can often be addressed through minor dermatologic surgery on the same day.

Who Benefits Most from Mole Screening?

FotoFinder ATBM: Advanced Mole Scanner AI

Our clinic utilizes the FotoFinder ATBM (Automated Total Body Mapping) system, the gold standard in melanoma testing technology. Unlike standard photography, this molemap system combines high-resolution imaging with artificial intelligence.

The mole scanner AI automatically locates every mole, allowing for an objective comparison during follow-up visits. This removes the “guesswork” of human memory, making it the most reliable method for checking moles for skin cancer. By detecting the smallest changes early, we can identify cancerous moles in their most treatable stages, often avoiding unnecessary skin treatments or surgeries.

Expert Treatment of Moles

Moles will be surgically removed if they have any suspicious features. This usually involves a simple excision with a very narrow margin (about 1 mm) of normal skin around the mole, designed to minimise scarring. The removed mole is then sent to a specialist laboratory, where it is carefully processed and examined by an experienced pathologist who specialises in skin cancer diagnosis. This ensures the highest quality and accuracy of analysis.

If a mole is confirmed as benign (harmless), no further surgical treatment is required. However, moles may also be removed for cosmetic or practical reasons; for example, if they are catching on clothing, causing discomfort, or if you simply dislike their appearance. In these cases, different techniques may be used, such as flattening a raised mole or reshaping and shrinking a mole to improve cosmetic results. These options would be discussed with you in detail before treatment.

Some mole removal techniques may require a stitch, while others can be performed without stitches. Healing time varies depending on the site: on the face, most mole removals heal within 5–7 days, while on the body, healing typically takes 10–14 days.

Mole Screening & Results

Mole screening is a careful check of your skin, often using a dermatoscope (a special magnifying light) to look closely at moles and other pigmented spots. The aim is to detect skin cancers such as melanoma early, when treatment is most effective.

Benefits of mole screening

Tailored prevention: Provides advice about sun protection and your personal level of risk.

Early detection: Identifies skin cancers at an early stage, often before they become dangerous.

Peace of mind: Reassures you if your moles are harmless.

Accurate monitoring: Photos and digital dermoscopy can track changes over time.

Expert advice: Helps you understand which of your moles are normal and what to watch for in the future.

What to Expect During a Mole Screening Consultation

1. Medical History

Your consultation begins with a detailed discussion of your clinical background. Understanding your risk profile is the first step in checking moles for skin cancer. We will discuss:

• Sun Exposure & UV History: Your lifetime history of sunburns and travel to high-altitude or sunny locations.
• Current Medications: Some treatments, such as oral contraceptives for acne or HRT treatments, can influence skin sensitivity or pigmentation.
• Health Background: Conditions like PCOS and hormonal skin or underactive thyroid disease can sometimes impact overall skin health.
• Family History: A history of melanoma or atypical moles in your family significantly influences when to check moles professionally.

2. Comprehensive Skin Examination

You will then have a thorough examination of your skin using a digital dermatoscope.

• This device uses cross-polarised light to provide high-definition analysis of each mole.
• If appropriate, a full-body mole mapping will be undertaken or recommended. This records detailed images of your skin so that moles can be compared over time.

3. Next Steps if a Mole Appears Suspicious

If our melanoma test identifies an unusual lesion, we offer two main clinical paths:

• Monitoring and Review
  • If changes are uncertain, the mole will be carefully documented and reviewed again after 4–6 weeks.
  • If there are no significant changes, the mole map can continue to be monitored.
  • If there are further changes, the mole will be recommended for removal.
• Surgical Excision
  • If a mole looks clearly suspicious, removal will be advised.
  • This is done under local anaesthetic ( numbing solution injected into the skin with a very fine needle). The surgical procedure usually takes 30–40 minutes.
  • A small injection numbs the skin, the mole is removed with a narrow 1 mm margin, and stitches are used to close the area.
  • Stitches are removed after 5–7 days on the face or 10–14 days on the body.
  • The mole is sent to a specialist laboratory where a pathologist with expertise in skin cancer examines it.

4. Follow-Up and Results

• You will return to the clinic to have your stitches removed and to discuss your results.
• For most patients, no further treatment is required once the mole is confirmed to be benign.
• In a small number of cases, if cancer is diagnosed, further treatment or surgery may be required. This will always be explained in detail and managed appropriately.
