The Ultimate Keratin Plex Fusion is Terreamer’s luxury straightening treatment that combines Keratin Amino Acids with Plex Nanoplasty in one advanced service.

Designed to strengthen from within and smooth from the outside, it helps create exceptionally straight, healthier-looking hair with enhanced shine, softness, and resilience.

Powered by Carbocysteine and Glyoxylic Acid, and infused with collagen, silk protein, shea butter, and amino acids, it delivers high-performance straightening while remaining 100% formaldehyde-free

Two Treatments, One Appointment

Enjoy the benefits of both of our hero straightening systems in one service. Hair is left smoother, shinier, healthier-looking, and easier to manage with less blow-drying and daily styling.

Long-Lasting Results

Keratin Plex Fusion combines two advanced straightening technologies and can last up to 8 months with the right aftercare.

Results vary depending on hair type and lifestyle.

Double Repair

Keratin amino acids help smooth and support the outer cuticle, while Plex Collagen helps support the internal hair bonds — delivering double repair in one appointment.

No Downtime

Style your hair straight away — wear it up, down, or clipped with no waiting period.

Same-Day Colour

Colour can be booked with your Fusion treatment for a full transformation, although we recommend waiting 48 hours or two washes for best colour absorption.

Keratin Amino Acids – Strengthen and rebuild the hair’s structure from within, boosting elasticity and shine while sealing the cuticle for a smooth, frizz-free finish.

Amino Acids – Work deep into the cortex to restore strength, repair bonds, and add healthy shine.

Natural Oils & Butters – Provide intense hydration, protect against heat, and keep hair soft, supple, and manageable.

Glyoxyloyl & Organic Acids – Gently restructure the hair’s natural bonds for lasting smoothness and resistance to humidity.

Your journey begins with an in-depth consultation to assess your hair’s health, history, and goals.

We start with the Plex Nanoplasty step to repair and fortify from within, followed by our Signature Keratin step to smooth, seal, and lock in moisture. Heat activation ensures both treatments bond deeply with the cuticle for maximum strength, sleekness, and shine.

The result? Stronger, healthier, and flawlessly smooth hair that stays beautiful for months.

Maintain Your Results Longer

With proper aftercare, your Fusion treatment can last up to 8 months. Includes our 30-day Happy Hair Guarantee.

Use Salt-Free Shampoo

Always choose Terreamer's Sodium Chloride (salt free) shampoo to protect your treatment and cuticle health.

Wash Sparingly

Limit to 2 washes per week to preserve smoothness.

Avoid Pools & Ocean for the First Week

Chlorine, salt, and minerals can weaken the treatment.

How long does it last?

6–8 months with proper aftercare — our longest-lasting smoothing service.
READ: It depend on your current hair condition, lifestyle and how you maintain it. Some of these can significantly shorten the duration.

Is it formaldehyde-free?

Yes — 100% formaldehyde-free and free from harsh chemicals.

Who is it for?

Perfect for those wanting both the sleek, frizz-free finish of keratin and the deep repair of plex nanoplasty in one session.

Is it safe for coloured or blonde hair?
