I'm Louisa Flanagan

Nail & beauty educator, salon owner, and course creator with 25+ years of real-world experience.

I've been working in nail and beauty since I was 18 — that's over 25 years of teaching, treating clients, running salons, and learning how the industry actually works, not just how it looks in a training manual. Today I own and run two nail and beauty salons in Dublin under the Nail and Beauty Bar name. My team treats real paying clients every day. Every technique I teach in our online courses has been tested, refined, and used on real salon clients before it's ever filmed. What looks good on a mannequin and what works at €60 an appointment are sometimes very different things — and after 25 years, I know the difference. I built NSI Online Courses because I watched too many talented women spend €2,000+ on training that left them uninsured, unprepared, or both. Every course here is AIT (Associated Irish Therapists) and ABT accredited — the qualifications Irish and UK insurers actually recognise when issuing professional indemnity cover. Without that accreditation, you can pass every module and still not be able to get insured to practise. I designed every course myself, based on what we teach and do in my salons. The videos are filmed in real salon conditions — proper lighting, real tools, real techniques. Lifetime access at €100 per course, so you can go at your own pace without losing out.
