IA Dermatology was founded to offer something increasingly rare in modern healthcare: time, expertise, and truly personalised dermatological care.
Led by Consultant Dermatologist Dr Iaisha Ali, together with Dr Shirin Zaheri, the clinic is built on the belief that skin and hair conditions are never just surface-level concerns. They affect confidence, identity and quality of life – and deserve thoughtful, science-led care delivered with empathy and precision.
We provide evidence-based diagnosis and personalised treatment for complex skin and hair conditions, with particular expertise in hair loss, women’s health, and hormone-related dermatology. Our approach is holistic and medically rigorous. We look beyond visible symptoms to identify underlying biological and systemic factors, creating tailored treatment plans designed to achieve lasting clinical outcomes.
In aesthetic care, we prioritise natural regeneration – supporting collagen production and skin repair – to deliver subtle, balanced enhancements that preserve individuality and long-term skin health.
IA Dermatology brings together academic excellence, decades of consultant-level experience, and a deeply personal approach to patient care, specialising in complex, hormone-driven and long-standing dermatological conditions.
