Hi Gojja,
Here's a stylist in the UK that does a really good job:
Martin McMillian
his name is Martin and can be reached at mmacmillan@hotmail.co.uk
United Kingdom
I don't have any experience with the NX-Gen Unifying Agent so I'm sorry but I can't help you with that.
If your hair needs some moisturizing I suggest 'Creme of Nature.' Its a combination of shampoo, detangler, and conditioner. It don't know if it's carried in the EU so you might have to order it on line. It's only about $5 and it's as good as anything costing several times the price. A good tape to use is 'Walker No Shine' tape. As the name implies it has no shine.
Best,
John
