Question 1

Is the Diamond System truly formaldehyde-free?

Accepted Answer

Yes. The Diamond System V6.0 uses a proprietary L-Cysteine + Tannic Acid matrix that achieves molecular realignment without any aldehydes — including formaldehyde, glutaraldehyde, or glyoxal. Independently tested. UKCA / CPSR compliant.

Question 2

How long do the results last?

Accepted Answer

The Diamond Protocol delivers structural harmony for up to 12 weeks per application. Results vary based on hair type, maintenance routine, and environmental factors. Most clients rebook every 10–12 weeks.

Question 3

Is it suitable for all hair types?

Accepted Answer

Engineered for all hair types, with particular efficacy on 3A through 4C textures. 6D SEM validation confirms cuticle alignment across the full spectrum of hair porosity and curl patterns.

Question 4

What is the salon profit margin per application?

Accepted Answer

Each 1-litre bottle yields 15+ applications at approximately £16 product cost per treatment. With a typical salon ticket of £250–350, salons can achieve up to £3,500+ in estimated gross profit per bottle.

Question 5

Do you offer training for salon professionals?

Accepted Answer

Yes. Trade registry members receive complimentary access to the Diamond Protocol Masterclass — video tutorials, timing guides, and direct consultation with the UK technical team based in Luton.
