Advanced Ingrown Hair Course

Specialist Training for Wax & Sugar Therapists

The Advanced Ingrown Hair Course is a professional, specialist-level training designed to help wax and sugar therapists move beyond standard techniques and deliver truly bespoke, results-led client care.

This course supports therapists in stepping into the leading edge of the beauty industry, where services are no longer generic, rushed, or one-size-fits-all — but built around individual skin needs, advanced techniques, and confident client education.

A key part of achieving long-term results is personalised skincare and aftercare — not generic product recommendations. This course shows you how to confidently deliver both.

Why This Course Exists

One of the most overlooked causes of ingrown hairs is hair breakage.

Inside this course, you will learn 7 Elite Wax & Sugar Techniques — Sarah Louisa’s signature methods — designed to:

Reduce hair breakage
Improve regrowth quality
Builds trust and client satisfaction

These techniques better results and experiences, without relying on standard wax/sugar hair removal techniques.

What You Will Learn

Advanced Ingrown Hair Science & Biology

The first-ever Ingrown Hair Biology Risk Factor framework
Why ingrown hairs are not simply caused by curly hair.

This is the first time since 2002 that science and real salon-based ingrown hair client experience have been formally brought together into one professional education. Exciting!

Client Journey Support

The course includes 3 structured system tools that support therapists through the full client journey — from consultation to skin recovery — helping you deliver specialist-level care with confidence and professionalism.

Advanced Ingrown hair advise & Tool Techniques

Advanced IngrownOut® Tweezer (hook) tested in practice since 2002 and loved by wax therapists worldwide since 2023. You are taught how to remove ingrown hairs safely without breaking/piercing the skin. Preventing bleeding, infection or scaring.
Training on 5 stages of ingrown hairs. Why this happens, how to prevent and how to clear ingrown hairs stage 1 and 2 and when not remove.

This ensures ingrown hair correction is performed with precision, safety, and professional judgement — reinforcing your role as a specialist.

Infection Control, Hygiene & Follicle Protection

Infection prevention, sterilisation, and salon hygiene control
How to protect hair follicle health after waxing or sugaring
How to support skin health through correct post-treatment care for each skin type.

Personalised Skincare, Aftercare & Client Confidence

This course teaches you how to move away from generic aftercare advice and into confident, personalised skin support.

You will learn how to:

Assess individual skin types and tailor aftercare accordingly
Use done-for-you research on professional trade skincare companies suitable for wax therapists
Recommend aftercare confidently, without feeling awkward or salesy
Use the correct language so clients understand why aftercare matters for skin health in between waxing.
Increase client follow-through and exercises to help stop feeling responsible when advice is ignored

If you’ve ever felt uncomfortable recommending aftercare — or noticed clients don’t follow through — this course is specifically designed to help you build confidence, clarity, and consistency.

This started in 2002 in the UK:

Everything I teach inside the Advanced Ingrown Hair Course is built from real salon experience — not theory alone.

Since 2002, I’ve worked with my tool the trade mark hook on my IngrownOut ®Tweezer. I’ve been hands-on waxing, sugaring, monitoring client skin behaviour, ingrown hair correction, product systems, and client psychology. Over time, it became clear that one technique, one product, one product routine and one approach does not suit every client.

This course exists to bridge the gap between science and real salon services, teaching therapists for the first time how to personalise body skin care, prevent hair breakage, protect follicle health, and confidently guide clients through aftercare that delivers lasting results.

It reflects a new way wax and sugar therapists show up — authentic, confident, and specialist-led — for clients who want a higher level of bespoke care that has never formally existed in the industry before. Sarah Louisa has walked the walk and talked the talk as she has treated 1,000’s of loyal clients.
