More information

What's Included

A thorough, tailored service for dense lengths.

  • Personal consultation to understand your goals, lifestyle and hair history.
  • Clarifying cleanse to prepare the cuticle for even absorption.
  • Keratin-rich smoothing formula applied in fine sections through the lengths and ends.
  • Precision blow-dry and heat sealing calibrated for long, thick hair.
  • Smooth, glossy finish plus personalised home care guidance.

Who It's For

If your long or thick hair is prone to frizz, expands in humidity or feels bulky and hard to manage, this service is designed for you. It is ideal when you want to keep movement and shape, yet reduce daily effort and achieve a refined, polished look.

It also suits anyone who heat-styles frequently and wants faster styling with less stress on the hair. The result is softer volume, improved manageability and lasting shine.

Duration & Appointment Timing

For long or very thick hair, allow around 3 to 4 hours. Exact timing varies with density, texture and previous treatments.

Your appointment includes cleanse, application, blow-dry, heat sealing and a smooth finish. If you are planning colour services, ask about ideal sequencing so both treatments perform at their best.

Aftercare & Maintenance

Use sulphate-free, salt-free shampoo and conditioner to preserve the smoothing effect. Apply heat protectant before styling and avoid unnecessary high heat.

Some systems allow immediate washing while others advise a short wait. Your stylist will confirm the correct guidance for your treatment.

Rinse after swimming and protect hair from chlorine and sea salt. With the right care, results typically last around 3 to 4 months; book a refresh when hair begins to feel more textured again.

Frequently Asked Questions

How long will the results last?
With the right aftercare, smoothing typically lasts around 3 to 4 months. Washing frequency, product choice and heat styling habits can influence longevity. Your stylist will tailor advice for long or thick hair.
Will this make my hair straight?
This is a smoothing treatment, not a chemical straightener. It reduces frizz and bulk, softens curl and wave, and leaves a sleeker, more polished finish. For a glass-straight look, you can still blow-dry or use irons with less effort.
Is it suitable for coloured or highlighted hair?
Yes, most coloured and highlighted hair responds well and often looks glossier. Your stylist will assess condition and adjust the technique to protect both colour and hair integrity. A toner top-up may be suggested if needed.
How should I prepare and what should I expect on the day?
Arrive with hair free from heavy oils or build-up. The service includes a clarifying cleanse, section-by-section application, heat sealing and a smooth finish. Allow extra time for long or very dense hair.
What aftercare products should I use?
Use sulphate-free, salt-free shampoo and conditioner to preserve the result. Apply heat protectant before styling and rinse hair after swimming. Your stylist can recommend a home care routine tailored to your hair.
