[color:#006600]I used rotary epilators for a while. Actually, anyone can go back on my posts and dig the posts up if they wanted. Anyway, I found that rotary epilators did not make my hair get gradually thinner. Not at all. In fact, it made fine hairs grow back a bit coarser.
What I found, was that hairs that were whispy, tapered, and had natural curve to them, when rotary epilated, would grow back straighter, darker, and no longer had the natural contour whispiness. They were like “Frankenhairs” , they grew out very unnatural looking. The direction and shape of the hair no longer matched the contour of the skin. I hated the look. And this is first hand experience I’m talking from.
Now, you didn’t say whether you , yourself, was thinking of using a rotary epilator. If you are, DON’T. They are terrible. They are more accurately “ingrown hair machines”, I got tons of ingrowns from using them, and I followed all the precautions and aftercare. It still didn’t help. If you’re going to do anything similar to that, instead, learn to wax. For some reason, it’s much better at effectively pulling out the hairs uniformly and gently.
Rotary epilators will give you “oatmeal” skin :o. It’s this lumpy appearance that results from all the harsh breakage and trauma the skin undergoes with rotary epilation. I can always spot someone who rotary epilates, even to this day.
Anyway, hope it answered your question, and then some.[/color]
