Indeed a case like yours seems “easy” but could be called the “Olympics of hair removal." Such a case like yours is perfect for the insulated needle and the automated thermolysis units. It’s a challenge because these hairs are shallow and, consequently, the potential for skin damage must be considered. (Your 13 hours so far is not a-typical.)
I’ve just come to the end of a massive “beard case” on a very wonderful woman (she was plucking … then shaving … and now nothing). Now that the shaving has ceased, the “undergrowth” has appeared.
Explanation: since tiny (vellus-type) hairs grow slower than large terminal hairs, the on-going (daily) shaving “hides” the tiny hairs: the patient does not realize these hairs even exist! Once the large terminal hairs are removed, and shaving stops, these “vellus” hairs appear. They were always there; the electrolysis did not convert the terminal hairs into vellus hairs.
I know this is not your case, but thought it might be helpful to point this out to other patients that are experiencing this very common phenomenon. To be honest … I’m PRAYING that is terrific client does not notice these nearly microscopic hairs. So far, she is not focusing on them. (I did point them out and explained what happened.) My forte is not “vellus hair” so I will recommend my favorite colleague in the area that loves this work and is better at it that I. (This little town is great: all of us in the field work together and are not competitive. It’s ONLY what the client needs!)
