Applied properly, extensions do not harm your natural lashes. Each one attaches to a single lash, sits away from the skin, and falls away when that lash sheds, which it was going to do anyway. Damage comes from three specific failures: too much weight, careless application, and what happens at home. All three are preventable.

The contradictory stories you have heard are usually both true
One woman has worn extensions for six years and her lashes are fine. Another had a single set and swears hers never recovered.
Neither is lying. The difference is not luck, and it is not the concept. It is which of the three failures below was present, and that is worth knowing before you book rather than afterwards.
Weight is the first risk, and the reason a good technician says no
A natural lash is a hair growing from a follicle, and there is a limit to what it can carry. Attach something significantly longer, thicker or heavier than the hair itself and you have hung a weight on it for the next several weeks.
The lash then sheds earlier than it should. Do that set after set and the follicle spends years producing hairs that keep getting pulled out ahead of schedule. Some eventually produce thinner hairs, or stop keeping pace.
This is why a technician sometimes declines what you asked for. If you want dramatic length on fine lashes, the honest answer is that they will not carry it. A technician who agrees to everything is not being accommodating. She is making a decision you pay for later. The safest sets stay close to your own lash length and use finer, lighter fibers when volume is wanted, and they usually cost less than the set you walked in asking for.
The failure that does the real damage is one most clients have never heard of
Every natural lash sits at a different point in its own cycle. Some have weeks left, some days. Proper application means separating one lash from its neighbors and bonding the extension to that lash alone.
When a technician works too fast, two or three natural lashes get glued together. They are now stuck to each other while growing at different rates. The longest keeps growing and drags the others with it, pulling them out of the follicle before they were ready. That is genuinely damaging, and it is the source of the gaps and thin patches people describe.
Ten seconds with a clean brush will tell you whether your set is safe
Run a clean spoolie slowly through your lashes, base to tip, for about ten seconds.
They should move independently and comfortably. If the brush catches, if you feel tugging, or if the lashes move in clumps rather than singly, lashes are stuck together and the set needs checking.
Here is the line worth drawing. Whether a set looks too full, too long or uneven is a question of taste, and it is a conversation with your technician at your convenience. Tugging when you brush, pinching when you blink, a lid margin that is red, itchy or sore, or the feeling of extensions touching your skin are not questions of taste. They mean something is wrong now. If your eyes stay red, sore or swollen, that is a conversation with a pharmacist or optometrist rather than another appointment.
The third failure happens at home, and it is the most common
Never pull off an extension. Never pick at a set that is growing out, however tempting the one lash sitting at a strange angle becomes. The bond is stronger than your natural lash, so what comes away in your fingers is usually both.
Professional removal takes fifteen to thirty minutes and uses a solution that dissolves the adhesive. It costs little against the price of a set, and it is the easiest way to protect your lashes.
Cleaning, by contrast, is protective rather than risky. People avoid washing the area for fear of loosening extensions, and the build up that follows leaves a red, itchy lid margin, which makes lashes shed faster. A daily wash with a proper lash foam keeps the skin comfortable and makes sets last longer.
The shed that looks like damage usually is not
When a full set is removed, your natural lashes look shockingly sparse. Part of that is comparison, because you have spent months looking at longer, darker lashes. Part of it is timing, since lashes that would have shed gradually all come away at once.
It is alarming, and usually temporary. Natural lashes take a couple of months to cycle through and fill back in. Lasting thinning does happen, but it comes from years of heavy sets or repeated poor application rather than from one bad experience.
What to ask for
Extensions are safe when they are light enough for your lashes, applied one to one, cleaned daily and removed professionally.
Do the spoolie test two days after your next set, and if anything catches or tugs, ring the salon that week rather than waiting for your infill.
