At what point in laser treatments does paradoxical hypertrichosis become evident? Does it happen after
first treatment or can it happen at a later time?
If it doesn’t happen after the first 3 or 4 treatments
does it mean it won’t happen?
Or can it become a problem months or even years after the
laser treatments are completed?
I think that’s a tough question. There are so many variables to account on this subject… From what I’ve understood from various posts is that this occurrence is not really that well studied.
The best thing I can say is that the best one can do is play it safe and be sure that the areas and type of hair treated are not one of the areas prone to hair stimulation. Also, type of laser, etc… Patch tests…
From my personal experience I think one should be patient. I think if the energy used is always the same there’s no reason why these affects won’t be noticed right after the first treatment. This of course, if you wait those 6 months I hear a lot in here.
Also, it helps a lot if you keep photos of the before treatments, even if it is to yourself. One can easily forget about what it looked like before.
Just my humble opinion, I’m in no way an expert. Just thought I’d say somehing because I know what it’s like to wait for someone to answer.
I’m looking forward to see the pro’s input on your question.
Jonhyvb did a great job answering your post, austingirl. I recall a poster in the past saying that she noticed more hair after the second treatment. Since we are all individuals, that may not be the timeline for you or others. This is not a probable outcome for many. They do just fine with laser in risky areas for hair stimulation. You never know how things are going to go. It is a gamble. Experienced laser specialists have some things they can do to perhaps minimize the risk.
I noticed longer, dark velus hair several months after the only laser treatment I had, at an area of the legs where I only had short velus hair (top part of the thigh).
If you want to be 100% sure, don’t let them lase you unless they use a good laser with strong settings at an area where the hair is dark & wiry like pubic/underarm hair. It should be ok then.
LIHG ( Laser induced hair growth ) usually may happen after an area that has fine and thin hair is stimulated by wrong settings and/or wrong wavelength application.
I have never seen this on the legs but have seen it on the NECK, UPPER ARMS and
sometimes the JAWLINE. Sideburns is also a dangerous area to treat , if the hair is very fine.
