With over 35 years of global expertise spanning the UK, USA, Australia, Germany, and Ireland, Dr. Shahid Abbas is a visionary in root-cause allergy care, immune reprogramming, and cosmetic immunology. His philosophy is simple yet revolutionary: As Chief of Allergy, Immunology & Vaccine Production at NIH Islamabad (1990–2003), Dr.Abbas pioneered Sublingual Immunotherapy (SLIT)—introducing it to patients in Pakistan, Saudi Arabia, and Dubai long before global acceptance. Trained by the World Health Organization in the USA in allergen extract production and standardization, he challenged conventional medicine with a safer, patient-friendly alternative. Although initially met with skepticism, Dr. Abbas’s groundbreaking work was later internationally validated. In collaboration with Medisca USA, he developed the world’s first Multi-Allergen SLIT Tablet (M-SLIT™)—a personalized, cost-effective therapy now used across continents. While conventional SLIT tablets are still produced and sold globally as single-allergen units, patients requiring immunotherapy for multiple allergens often face a steep financial and logistical burden. For example, treating four allergens typically means purchasing four separate tablets, taken daily for three years, costing up to $1,600 per month. In contrast, Dr. Abbas formulates a customized, four-allergen single tablet—tailor-made for each patient—at nearly one-tenth the cost, without compromising on international quality standards. His innovation not only makes advanced immunotherapy more accessible, but also simplifies treatment and enhances compliance, offering a truly patient-centric solution. Dr.Abbas avoids lifelong symptomatic medications and instead delivers immune-targeted therapies that restore health, enhance appearance, and minimize side effects. His approach is trusted by patients seeking lasting transformation—inside and out. Whether treating chronic allergies, autoimmune conditions, or cosmetic sensitivities, Dr.Abbas blends scientific precision with compassionate care—empowering patients to heal, thrive, and reclaim their confidence Services and Specializations Dr. Abbas provides expert care in allergy, immunology, and dermatology, with a focus on treating the root cause of conditions rather than just the symptoms 1 .

Reviews from our International Patients-Dubai & Pakistan Clinics
Aisha Khan,Position
Allergic to dyes, MelaninRegain reactivated my natural black hair color. After four months, my hair is genuinelyreverting with no irritation.
Li WeiPosition
Skeptical at first, but after three and a half months, my Asian hair is remarkably darker. It works at themolecular level, not just as a cover-up.
Priyanka Sharma,Position
As someone with PPD allergies, MelaninRegain was a miracle. My Indian black hair isback, healthier than ever, thanks to its molecular action over three months.
Sophie DaviesPosition
My dark hair is important, but allergies prevented coloring. Four months ofMelaninRegain has subtly and effectively reversed the greying by working at a molecular level.
Sophie DaviesPosition
My blonde hair was dull with greys, but dyes irritated my scalp. Three months ofMelaninRegain brought back my vibrant natural blonde by reactivating pigment.
Rajeev GuptaPosition
My hair and beard were greying, but dyes caused severe reactions. Four months ofMelaninRegain has significantly restored their natural dark color by stimulating melanin.
Oliver MorganPosition
Premature greying and dye reactions led me to MelaninRegain. Over three months, my dark hair and beard are regaining their original color naturally, not just superficially.
Liam O'ConnellPosition
My hair and beard were greying, and dye-sensitive. Over three to four months, MelaninRegain brought back my natural dark brown, making me look years younger. Highly recommend it for anyone with dye sensitivity!
Gurdial SinghPosition
At 80, my beard and turban were fully grey, a mark of my years. This product (or similar) would represent the desire to maintain a youthful essence even in later life.
Kenji TanakaPosition
As an Asian with stubborn greys and dye allergies, MelaninRegain was my only safe option.In just 3–4 months, my hair and beard regained a natural, youthful dark tone through real pigment restoration.I highly recommend this product to anyone with similar concerns!
Ahmed ZahidPosition
My grey beard made me look older, but I’m allergic to dyes.After 3 months of using MelaninRegain, my hair and beard returned to their natural black.It truly works at the molecular level — highly recommend this product!
