If you apply the hair straightening treatment:

When you do the Nanoplasty treatment: 

3 days before the treatment or 4 weeks after application as it will shorten the effect of the treatment.

How long does a DIANA treatment take?

Our treatments are personalised to hair type and condition, so the exact time will vary. It’s usually somewhere between 2-3 hours (Hair B-Tox & Golden Pro Protein) and 4-5 hours (Nanoplasty). Lamination and instant treatments are express treatments giving instant results within 1 hour (or less!).

Why do I need to use a titanium straightener?

Using a wide plate titanium straightener helps to lock in the treatment. The titanium straightener is amazing for quick styling as it heats up in no time and completely straightens your hair in just a few passes.

Our wide plate straightener covers more surface and therefore is a lot more efficient when running it through strands. Due to this, they are also perfect for thick hair as they can grip onto this better and so will do a better job at straightening this type than if you were to use thinner irons.

You can find the right iron in our online store that delivers faster straightening on thicker, curly, and unruly hair, while a high heat of up to 249°C will straighten the tightest ringlets.

Please contact your Diana Representative to find the best straightener for our treatments.
