Tria Hair Removal Laser 4X

Shaving is a temporary solution to the permanent problem of unwanted hair. It’s a money and time suck and the cycle never ends! I decided to try Tria’s Hair Removal Laser 4X, the only diode laser cleared for home use by the FDA. Getting professional laser treatments on my legs would have cost upwards of $5,000.00, so the Tria’s $449.00 price tag seemed like a bargain, especially since it uses the same technology found in professional laser spas! Here’s some information you might find helpful if you’re considering purchasing a Tria or deciding between a Tria and professional treatment:

My System

Here are the basic instructions for use:

  1. To prep, shave and towel dry the area you’re going to treat.
  2. Unplug and turn the device on by pressing the power button.
  3. Unlock the Tria by holding the bottom of the device against the area you’re going to treat. This makes sure the Tria is safe to use on your skin tone.
  4. Press the power button to adjust the power level–there are five. You should use the highest level you can tolerate. I used level four on my legs.
  5. Press and hold the treatment window to the area you’re treating until you hear two beeps.
  6. Pick up the Tria and treat the next area until you hear two beeps–this spot should overlap the last area you treated.
  7. Continue to work in an overlapping pattern until you’ve treated the entire area. Keep track of the number of pulses using the pulse counter located on the top display. One lower leg, for example, should take about 600 pulses and 25-30 minutes to treat. See the Tria 4X Quick Start Guide for more info.
  8. If you’re treating a large area, your Tria will probably be dead by the time you finish, so plug it in when you’re done!

Because I was treating a large area, I found it difficult to remember which spots I’d already been over. I ended up drawing a grid on my legs with an easy-to-remove eyeliner to keep track and drawing an X through each little square as I finished it. It sounds complicated, but I would have been totally lost without this system.

The battery only lasts 30 minutes, or long enough to treat one upper or lower leg. It also takes a full two hours to charge. I’ve found that the most efficient way to get both legs done in one day is to shave one leg, draw the grid on it, treat the lower half of it, charge my Tria for two hours, treat the upper half and then repeat the process with the other leg. The whole process is very time consuming, but I can obviously do other things while the device is charging. I did this every two weeks until I had completed eight treatments.

How it Worked For Me

  • I didn’t notice a difference in the amount or rate of regrowth after the first two treatments.
  • After the third treatment, I noticed that the hair on my legs had started growing in much softer and at a significantly slower rate. After five days without shaving there was still hair in all the places I’d been treating, but it was so much shorter and softer than before laser.
  • With each subsequent treatment, the hair started growing back slower and slower until there was barely any stubble even after a week without shaving.
  • After completing all eight treatments, I’d say there is about a 90% reduction in hair growth on my lower legs and close to 100% on my upper legs. I still need to shave about every week and a half if I want my legs to feel completely smooth, but they look almost hair-free, even from close up. I think I’ll do a couple more treatments once the summer is over to see if I can further reduce the hair growth on my lower legs.


  • It works. I’d estimate a 90% reduction in hair growth. The hair that does grow back is also much finer than it used to be.
  • It’s so much less expensive than professional treatment. I got a quote for over $5,000.00 for six treatments on my upper and lower legs at a professional laser spa…the Tria costs just under $450.00 and is also available on a payment plan.
  • You can do the treatments in the privacy of your own home and you don’t need to make an appointment.
  • offers a 90 day money-back guarantee.
  • It’s relatively painless, even on the higher treatment levels.


  • Only works on lighter skin tones and dark hair. See if it will work for you here.
  • Treatments are time consuming because the Tria’s ‘treatment window’ is small.
  • The battery only lasts 30 minutes and you can’t use the Tria while it’s charging. See ‘My System’ for more about this.
  • It’s easy to lose track of which places you’ve already treated, especially when you’re working on large areas like legs. See ‘My System’ for my workaround.
  • Pain is subjective, so you might find the process more painful than I did.

Bottom Line

The process is a much bigger time commitment than I realized, but I’m really happy with the results. I would definitely recommend this laser to anyone looking for professional, permanent results without the high-end price tag.
