With the fundamentals mastered, the next step is to practice classic lash application on your mannequin. The application process for volume lashes is nearly identical, except there are additional fanning techniques that you will learn. Watch our expert demonstrate each of the key skills required to apply a full set of lashes.
Very soon, you will be required to commence your first assessable activity, Major Assignment 1 [MA1]. This will require you to complete full sets of lash extensions on your supplied mannequin head. The below AED video will detail how to prepare your mannequin head for practice lash extension application.
No lash technician ever woke up one morning and was able to control his or her fine motor skills to the level required to apply individual lash extensions onto an eyelash. This is a skill that takes practice, practice and then some more practice.
The below two AED videos outline lash extension practice drills that will prove critical to your development as a lash technician. Take your time to view these demonstrations and complete the below Practical Activity before progressing any further with this course. While Practical Activities are not assessed, failure to complete them will very likely be obvious to our course tutors when assessing your Major Assignments later in this module.
The next skill for you to master is effective isolation of single lashes. This will be done utilising your practice mannequin head prepared with a practice lash strip, as demonstrated in the AED video at the start of this module. Watch the below AED video for a demonstration of effective lash isolation on a mannequin head.
You have now completed the required training drills to progress onto applying a full set of practice lash extensions onto a mannequin head. When you are practising full sets for the first time, you may need to take little breaks. Physically your body may not be used to sitting still for so long, and mentally you might become exhausted from all that concentration! It is important that you perfect your application on a mannequin before moving onto real models.
Watch the below AED video to see a full set of classic lash extension applied to a single practice lash strip on a mannequin head.
When applying lashes on a model, there are extra steps that you will need to complete. For example, you will need to cleanse the eyelashes (not required on a mannequin!), and you will also be working with natural lashes that will likely be different to your training lashes. Watch our expert demonstrate each of the key skills required to apply a full set of lashes to a model:
As you saw in the demonstrations, there is a specific order steps must be completed. As a recap, when applying lashes on real models, you need to:

Even the most experienced lash technicians can run into issues. Some problems can be easily avoided, and some will happen, even if you have done everything correctly! Remember, temperature and humidity can impact retention, so you need to ensure that your workspace has a humidity level between 45%-60% and a temperature of 22-26°C / 71-79° F. Retention can sometimes be quite tricky even as an experienced lash tech. We will see clients that have strange patterns with retention as well as clients that just cannot keep their lashes on. Sometimes there is no reason as to why this is happening, but the following can be major causes of poor retention:
To combat retention issues, always ensure:
Being a mobile lash technician is not advisable. There may be some instances where it could work, but most often, you will be unable to control your environment. If possible, set up your own studio or rent a space – it will be so much easier in the long run and will ensure you don’t damage your reputation!
