Inflammatory & Autoimmune Conditions
Conditions driven by the immune system or chronic inflammation can affect skin stability and hair growth.
Discoid Lupus Erythematosus (DLE)
A chronic autoimmune condition that can cause red, inflamed, and scaly patches on the scalp. Without treatment, this can lead to scarring alopecia (permanent hair loss). [Read Guide]
Psoriasis
An autoimmune condition causing the rapid buildup of skin cells, resulting in thick, silvery scales and red, itchy patches. It is often mistaken for severe dandruff but requires specific management. [Read Guide]
Eczema (Seborrhoeic Dermatitis)
A common condition caused by an overreaction to natural scalp yeast (Malassezia). It presents as greasy, yellowish scales and redness, often affecting the hairline and eyebrows. [Read Guide]
Scaling & Sensitivity
Conditions characterised by shedding skin cells, dryness, or persistent irritation.
Dandruff (Pityriasis Capitis)
White or grey flakes and mild itching characterise the most common scalp complaint. While often cosmetic, persistent dandruff can indicate an imbalance in the scalp’s microbiome. [Read Guide]
Itchy Flaky Scalp (Pityriasis Amiantacea)
A more severe form of scaling where thick, asbestos-like scales stick to the scalp and hair shaft. This condition can cause temporary hair loss if the scales are removed forcefully. [Read Guide]
Allergic Reaction (Contact Dermatitis)
Sudden itching, redness, or blistering caused by a reaction to hair dyes, shampoos, or styling products. This is a sensitivity to a specific chemical ingredient. [Read Guide]
Infection & Irritation
Conditions caused by bacteria, parasites, or the “itch-scratch” cycle.
Folliculitis
Inflammation of the hair follicles often appears as small, red bumps or white-headed pimples. Bacterial or fungal infections can cause it and may lead to scarring if left untreated. [Read Guide]
Neurodermatitis (Lichen Simplex)
A skin condition characterised by a chronic itch-scratch cycle. The skin becomes thickened and leathery due to constant scratching, often triggered by stress or anxiety. [Read Guide]
Diagnosis & Treatment Pathways
- How We Diagnose Scalp Conditions: Correct diagnosis is vital. Shuna uses clinical trichoscopy, scalp evaluation, and comprehensive analysis to identify the root cause, going deeper than standard GP checks.
- Treatment Options: We provide evidence-based treatment plans tailored to your specific condition, ranging from clinical therapies (such as scalp creams and steamers) to specialist home care programmes.
- Holistic Management: Scalp health is often linked to diet and stress. We provide guidance on lifestyle factors to prevent flare-ups.

FAQs about Scalp Conditions
What is the difference between Dandruff and Psoriasis?
While both cause flaking, dandruff usually presents as loose, white flakes. Psoriasis typically causes thicker, silvery scales on red, inflamed plaques and is an autoimmune response, whereas dandruff is often fungal or environmental.
Can scalp conditions cause hair loss?
Yes. Conditions like Discoid Lupus and Folliculitis can cause scarring (permanent loss). Others, like severe Eczema or Psoriasis, can cause temporary shedding due to inflammation or physical trauma from scratching.
Do I need a referral to treat my scalp condition?
No, you do not need a GP referral to book an appointment with Shuna Hammocks. As a private Consultant Trichologist, you can self-refer for expert diagnosis of itchy, flaky, or inflamed scalps.
How does Shuna diagnose these conditions?
Diagnosis involves a forensic approach: Clinical History (health and diet), Trichoscopy (high-magnification imaging to distinguish between conditions such as lice and dandruff), and, occasionally, blood analysis to check for inflammatory markers.
