Spa Junkie on… Japanese Diamond System

In search of a solution for dry, damaged, sun-ravaged locks, our covert reporter heads for a new treatment at hair rehab

I pride myself on trying out treatments both old and new, holistic and techie – but the one area I am often remiss about is my hair.

Eleven Hair is less hair spa, more hair rehab. In other words, it’s ideal for those like me who work a year-round Ibiza-boho look, don’t own a brush and regularly spritz volumising sprays – no doubt at the expense of countless hair follicles. My colour is another story entirely. I have frazzled and burnt in the pursuit of just the right shade of Bondi blonde. Add summer sunshine, sea, salt and chlorine to the mix, and you get hair that’s more straw than silk. There’s only one option for me: a new super-conditioning treatment called the Japanese Diamond System.

Developed by thermal treatment experts in Japan, the Diamond System claims to repair hair from the inside and provide protection against harmful external factors such as UV and styling products for up to eight weeks.  

I arrive at the Mayfair salon early and meet Gleb, the stylist who will be treating my hair today. As he tries (in vain) to run his fingers through my hair, it’s obvious that I am the ideal candidate for this treatment.

Gleb washes my hair with a clarifying scalp-cleansing shampoo to remove any remnants or build-up of product that might prevent the absorption of the Japanese Diamond formulations, and leaves it to deep cleanse for five minutes before rinsing it off.

The hair healing process begins by applying a selection of specially formulated deep-conditioning products to the hair by hand, section by section. Gleb explains that they include repairing and protecting ingredients such as argan oil, jojoba oil, rose oil, silk, cranberry and lavender. The thick goop smells good – floral, fruity and rich.


Next Gleb places a pane of clear perspex underneath each section of hair and runs a hand-held ultrasound device from root to tip. He explains that the pane of plastic reflects the ultrasound waves so that they lock the product’s naturally derived ingredients deep into the hair shaft to rejuvenate and restructure from the inside.

Finally, my hair is rinsed and a nourishing mask applied for 10 minutes. A wash and a blow-dry later and my hair has a glass-like shine, with the light bouncing off – something I haven’t seen for many years.

The bottom line:

My hair swishes and shimmers perfectly. I wash it two days later and even then it just needs a very quick flick of the hot brush and a touch of serum on the ends to keep it looking in fantastic condition.

The Japanese Diamond System couldn’t be a more comprehensive solution for dry, damaged hair and, once it’s worked its magic, it leaves hair so low maintenance you could jump out of bed and give Jennifer Aniston a run for her money.
