Upon purchasing the training course, we will send you a training kit (worth £200) consisting of the products you will need for the practical part of the training and a selection of promotional support material once you have received your certificate.

  • Bio Straight Treatment 100ml x2 (1-2 Treatments on average)

Once you feel confident with your new knowledge you can then start performing the treatment on one model. We ask that you to complete a short quiz and upload your results (before and after videos/short clips showing the process).

Lastly, once you have passed the practical assessment,  you will be sent a folder containing all the documents you will need to get started. We will post your International Nature Eva Certificate with your first order and include all the marketing material you need to get started (poster, window sticker, flyers, bowl, brush, spatula and more…)
