This is one of the reason I'm absolutely meticulous about my own cuticle care. Cuticle Eraser every night, regular solar oil + hand cream throughout the day and regular manicures with no cutting. My cuticles are perfect. Thin as possible, really neat and no hangnails, redness, etc.
It's the best persuasion tool if you come across a client who asks/insists for cutting of the eponychium. Yes you can explain all the hows and why nots and science bits but really the client is just interested in the end result.
Demonstrate you can achieve an even better result and their objections melt away. I also have a before picture to show that it isn't just that I have naturally great cuticles (they really are quite terrible if I leave them alone for a few weeks!) for any really skeptical clients!
It is also great to show why clients must follow their aftercare advice so then helps with retail.
Too often on here and in real life I see techs with great nails but terrible cuticles. It's a massive bug bear of mine!!
