Why is there such a price difference?
Quality of the product they use
Cheap products near the eyes, would you chance it?
How many lashes they apply
30 to 150, usually you need at least 75 to look nice.
What type of lashes they apply
The good lash brands can be expensive and they are properly tested for use on the eyes. The cheap lashes are very hard and not very comfortable to wear.
How long the lashes take to apply
30 minutes to 2 + hours, usually the more time, the more lashes you'll get.
How much the technician has invested in their training
Some companies give their training for nothing if you buy their training kit, some cost up to £1000.
How experienced they are
Its a bit like hairdressers, you pay more to see the top stylist, its the same with lash stylists.
The quality of the lash job
You might get one length and thickness applied across the eye or preferably a technician that shapes the lashes naturally to enhance the eye shape using many lengths, curves and thicknesses of lashes.
