Because this can cause Lash damage resulting in a frizzy effect
You can apply more glue which will soften the original product application allowing you to readjust the lashes, it will also help if you re-adjust by stretching underneath the lashes over the lash pad
If you apply a tint before a Lash Lift it will lift out the colour as well as Lashes are more porous after a lash lift so they will grab the colour better
This is because of the lash growth cycle, a lash extension will only last as long as your natural lash does.
You can tint the clients natural lashes so they appear darker, use flat lashes which create a darker lash line, or create volume fans using the lashes with the smallest diameter to give the appearance of more lashes.
You tint the eyebrows twice with a first initial tint which is only on for a short time to determine how porous the hair is and to tint the superfluous hair which makes it easier to see and therefore remove, your second application is to create definition to the shape and stain the skin to prevent clients filling in their brows daily.
We use 3 different methods of hair removal because there are different hair types, to ensure finer and courser as well we get the smoothest finish reach all hairs no matter the position of them, this results in a much more defined final brow shape.
Clients can have different skin types and their own personal preferences which require you to select the foundation that suits them best, If you do not select the best foundation for the clients base it will not sit correctly.
All make up has different consistencies and textures therefore different tools are required to apply these, using the wrong brush will result in improper make up application, there could also be an alternative brush which applies the product just as well but quicker.
This comes down to analysing the clients undertones and seasonal colour analysis which determine what colours suit who.
It needs to be thicker on the apex of the nail to ensure the extension has adequate support to prevent breakages.
We don't use electric nail files as it is extremely easy to over file and damage your clients nails which can create not only weakness but also a tender and burning sensation.
