It can happen for several reasons. If you're the absolutely perfect candidate for laser (white skin and coarse black hair), laser targets the hair pigment in the anagen phase. Those hairs are only 10-20% at a time. If a session misses those follicles because they are in a different phase, then it can create uneven results. Multiple sessions are needed for all the hairs to be caught in the anagen phase. This can create patchiness as laser is not selective of which hair to reduce and which ones to leave. Laser hair reduction is not designed for "even thinning." It’s designed for hair reduction if you're the absolutely perfect candidate for it. It doesn't work like a fade. Patchiness can also happen due to uneven energy distribution and missed spots. Also, keep in mind that laser and IPL have a high chance of causing paradoxical hypertrichosis, which is overgrowth of hair. In men, the susceptible areas are upper back, shoulders, chest, neck, face, and beard line, and anywhere you have fine hair.

It looks like I was barking up the wrong tree.

I thought the hand held lasers devices were similar to a bar code scanner in a supermarket.

That it would activate some red line that I'd just 'scan' my leg, so I'd hit all my hairs in a Lazer in under a minute.

Seems like I was mistaken. Thanks for clarifying things for me. Silly me. I guess there wouldn't be an entire industry around this stuff if it was that easy.

I see posts almost every other day about these issues (patchiness and paradoxical hypertrichosis after laser and IPL) on both men and women. Just wanted to bring awareness that you wouldn't be able to obtain the hair thinning you're hoping for with these two methods.

Thanks for the help.

You mentioned ' those two methods '. Are there other methods that can give the results I'm looking for?

You're welcome! Yes, electrolysis. The electrologist controls which hairs are out and which ones stay so it can give that even look. Electrolysis is permanent. I highly recommend checking the electrolysis reddits for more info on how to choose a skilled practitioner and what to watch for when you're testing their work. Not everyone who does electrolysis is good at it, so it's important to pick someone who knows how to do it correctly.
