Eczema Is a Barrier Disease
Understanding the Hair Cycle
Every hair on your head is in one of three phases at any moment: anagen (active growth, 2–6 years), catagen (transition, 2–3 weeks), or telogen (rest and shedding, ~3 months). On a healthy scalp, around 90% of hairs are in anagen at any time. Shedding 50–100 hairs daily is normal — anything more is pathological.
The four most common patterns of pathological hair loss are: androgenetic alopecia (genetic, DHT-driven, progressive), telogen effluvium (post-stress, post-illness, post-partum, post-COVID — diffuse and reversible), nutritional deficiencies (iron/ferritin, vitamin D, B12, protein), and thyroid dysfunction. Each requires a different protocol; misdiagnosis wastes 4–6 months and worsens psychological burden.
Why a Dermatologist with Trichology Specialism Is Different
Most hair loss patients have already tried OTC supplements, oils, online influencer recommendations, and salon serums — all of which target undefined “hair fall” without identifying the cause. Trichoscopy (digital scalp magnification) and a correlated blood panel change the conversation immediately. We see miniaturisation patterns invisible to the naked eye. We test for ferritin, thyroid, vitamin D, B12, hormone profile (especially in women). The result is a diagnosis — and from there, a real plan.
Treatment has two arms: restoring the barrier (medical-grade emollients, identifying and eliminating triggers) and controlling the inflammatory response (topical anti-inflammatory therapy, systemic therapy in severe cases). Newer biologic therapies have transformed outcomes in moderate-to-severe disease and are prescribable by dermatologists.
A mole is a collection of melanocytes. Most are entirely benign and stay that way. But some change — and the early signs of malignant melanoma are subtle: asymmetry, border irregularity, colour variation, diameter, evolution (the “ABCDE” criteria). A dermatologist evaluates these clinically and with dermoscopy (a magnified, polarised examination), then decides: routine removal, removal with histopathology, or referral.
This is why Mediglo never removes a mole without examining it first. We use radiofrequency electrocautery, CO₂ laser, or surgical excision depending on the lesion type, depth, and need for histology. Where there is any clinical concern, the specimen goes to histopathology.
When to Get a Mole Checked
Any mole that is changing in size, shape, or colour. Any mole that is itching, bleeding, or crusting. New moles after age 35. Moles in sun-exposed areas with irregular borders. Sudden appearance of multiple new moles. Erring on the side of being checked is the only correct instinct.
