If a treated hair comes out without resistence, the hair is killed forever? or will it grow back but thinner if it a very thick hair? my electrologist when she cannot get a very coarse hair and has to pluck it she says that since she has treated it will grow back thinner and then it will be easy to zap.

What actually is the golden standard indicator that the hair is gone for good?

If the hair bulb is big and the shaft narrow or distorted you might feel a pull when the hair comes out. It should not feel like a tweeze (with the pain of tweezing), just a pulling sensation.

If a hair is not completely killed the first time it can come back finer and/or easier to treat, depending on various factors including accuracy of insertion.

Thanks for answering if the hair comes out without resistence then it is gone for good?
I am going to a pro as well DIY partly to get this done. So wanted to be sure that should be the foremost aim to get hair without resistence and ofcourse not frying the tissue around.

Is it possible that that same hair will grow back if it was treated and came without resistence.?

A hair that was burnt off, and thus disconnected from the lower bulge area would come out without any resisitence at all, and you would grow hair again in that follicle.

Really, you need to find someone you feel comfortable in trusting for about 3 months, as with that amount of time, and copiously kept before and after treatment pictures, you will see the difference.

When the hair comes out, are you pulling out a coagulated root sheath?

ie, is there white gooey looking stuff attached to the hair root/bulb?

If you are getting coagulated root sheaths most of the time then it is likely the follicles are being disabled. The amount of coagulated tissue will vary depending on whether the hair was in anagen or catagen/telogen phase, but in general you should be seeing some coagulated tissue on every hair.
