It's pretty interesting. I've been through two home devices with little to no success. I tried a inexpensive IPL home device from Amazon and it did next to nothing on my pubic area. Then invested $400 on the Tria 4X and used it for a few months and just had a few areas that had hair reduction and that was it. After a few months of use, I still had a lot of hair growing back.
So after all that, I decided to fork over $1,100 for 6 sessions of professional laser treatments. I've done 3 sessions so far and the results are AMAZING! I have about 90% hair reduction on the pubic area, with most of the hair growth which is near the penis shaft, which is a very stubborn area. Hope to get most if not all of that in the next few sessions. If I have to pay for more sessions, then so be it. All I have to say is that professional treatments WORK and home devices suck!
I shave all my body hair and would love it gone for good, so I was thinking of getting one, but here is why I decided against it, an IPL or laser treatment basically destroys the hair folicals, great, no more hair!! But.. A lot of your skins melolin production is done in the hair folicals, ( which is why it is also used to lighten dark patches of skin). My worry is that if you limit melolin production, you won't tan as much which is your skins natural defence against uv rays, leaving you more suseptable to sun burn and skin damage, and I do like being out in the sun... So, think I'll just carry on shaving,
No regrets!
I visit a place where they have salon-strength IPL machine about once every 6 weeks. And in between I use an epilator to plug any unwanted hair anywhere. Loving the smoothness (which is different from shaving).
