Product questions

Before you choose Stratogen-3.

Is Stratogen-3 a straightening treatment?

No. Stratogen-3 is a repair treatment. It improves the feel, strength and shine of stressed hair but it does not replace the Amino-15 Hair Straightening service.

Who is it best for?

Use it for hair that feels brittle, dry, over-processed, heat-stressed or rough after colouring, styling or environmental exposure.

How often should I use it?

Most clients can use it weekly, or whenever hair needs a deeper repair step. Very damaged hair may benefit from professional guidance.

Can salons use heat with it?

Gentle heat can be used in a professional setting when appropriate, but the treatment is still rinsed out before styling.

Why it works

Repair care without changing the hair shape.

For clients who want a serious repair step for hair that feels fragile, dull, rough or overworked.

Strength support

Helps fragile lengths feel more resilient, flexible and less prone to a brittle finish.

Moisture return

Replenishes the feel of dry, rough hair with a soft rinse-off treatment finish.

Gloss and smoothness

Helps overworked hair look calmer, shinier and easier to style after treatment.

Formula notes

A richer treatment for stressed hair.

Patented sugar bond builders

Help rebuild hydrogen and ionic bonds so fragile hair feels stronger, more flexible and more resilient.

Liposomal pomegranate shield

Carries pomegranate antioxidants into the hair to help protect vibrancy and reduce colour fade.

15 amino acids + proteins

Hair-like building blocks from amino acids, wheat protein and carob help reinforce weak, porous areas.

Five oils + shea butter

Coconut, argan, almond, moringa and castor oils restore softness, flexibility and glossy shine.

Moisture-lock complex

Saccharide isomerate, sodium PCA, glycerin and sodium lactate help dry, porous hair hold onto hydration.

Cuticle-smoothing conditioners

Jojoba esters, conditioning lipids and easy-comb polymers improve slip and leave a polished finish.

How to use

How to use the treatment.

Cleanse

Start with freshly washed, towel-dried hair.

Apply

Work through mid-lengths and ends, concentrating on damaged, porous or brittle areas.

Process

Leave on for 5–20 minutes under a cap. Use a heat cap or gentle heat for even better results.

Rinse

Rinse thoroughly and style as usual. Use weekly or as needed for stressed hair.

Details

Where Stratogen-3 fits in the routine.

What it does

Supports stronger-feeling, softer, shinier hair through a concentrated rinse-off repair treatment.

Best for

Bleached, coloured, heat-styled, chemically treated or fragile hair that needs a weekly reset.

Not for

Changing curl pattern or replacing the professional Amino-15 Hair Straightening System.

Routine fit

Use after shampooing, then use in place of conditioner.

Treatment proof points

Repair care clients can feel after rinsing.

Stratogen-3 is built as a concentrated weekly treatment, not a standard hair mask, with a richer active profile for hair that needs visible care.

My hair is quite fragile and usually breaks after using heat a few times, but this treatment has really helped. After a few uses my hair already feels stronger, smoother, and a lot less brittle. It’s softer, easier to brush and has such a shine to it now. I leave it on for about 15 minutes and it rinses out nicely without feeling heavy unlike other products I’ve used. It also smells absolutely gorgeous!

I use the Stratogen-3 as a finishing touch during the mask rinse and blow dry, at the end of the Amino straightening treatment and it is fabulous! It makes such a different to any usual mask and thoroughly smooths the hair! I’ve just ordered this to use as a single service and I am so excited to use it on its own, after seeing the results already, after using the free tester pots I kindly got sent with my order! Highly recommend Rejuvenum products 🌱

I got amazing results from the Stratogen-3 Treatment! After a single use, my flat ironed, frizz-prone 2c/3a hair was able to stay straight and shiny for longer even through humid weather. It also felt noticeably smoother and stronger.

The Rejuvenum Stratogen-3 Molecular Repair Treatment delivers exceptional results. After just one session, my client’s hair felt stronger, smoother, and beautifully revitalized. It restores the hair’s internal structure while leaving a luxurious, healthy shine — a truly advanced treatment for deep repair and long-lasting resilience.
