Any tips on treating white hairs or very fine hairs? They are very hard to see - do you suggest:
- hair dye? Is there some type that doesn’t stain skin?
- magnification tools? If so, what?
You need good strong lighting and good magnification loupes. Don’t bother with dyes.
For loupes I’d recommend www.med-lite.com . That’s where I got mine. I’m not sure what you’re using now, but to go “to the next level” you need pro eye magnification. Trust me, I wasted money on so many pieces of poor eye magnification, then I just went to med-lites. Not the bestest, but entry level good pro.
As for lighting, spend money on something really bright. Mine combines a circline and halogen bulbs and I’d rate it as alright. Also, experiment with keeping the light not directly over the hair, but off at an angle. Sometimes that makes pale hairs easier to target.
Hope it helped. 
I use surgical loupes and a halogen light. The light is tilted at certain angles and the client is positioned accordingly. Sometimes I shade the area with my index finger. I can see the smallest hairs. I also enlist the client to help. I give them a mirror and they point out any hairs or areas I didn’t target that bug them. I may not agree that certain hairs need to go, but I listen to my client and do what they ask me to do.
Honestly, I do not see any point doing electrolysis on fine hairs. They are so easy to shave. And they usually grow back very slowly.
I am afraid that most people do not realize (like I did not before) that electrolysis is not a simply cosmetic procedure, but a very serious one. And I seriously do not see any point to involve it treating fine hairs. I am dealing with side-effects of electrolysis for six years, and still being too far from recovering.
I do think that doing LHR or electrolysis should be only the last possible option. Just shaving with proper shaving technique daily is the best solution EVER.
You know Ekade, I’ve read your posts and I don’t know what to say. I’m not a pro, I cleared out major body areas on myself, and did not have the ingrown problems you mention. During the process I would encounter them, but they passed and healed pretty quick. Btw, I haven’t shaved in a long time.
There are many that would consider fine hairs to be a nuisance, and sometimes when females shave facial hair, it gets alot more noticeable. Something tells me you might have very tight curly hair, do you? Because normally, electrolysis isn’t the negative experience you refer to. A poor insertion has nothing to do with an ingrown, and a partially killed hair doesn’t near mean it will grow back ingrown. And, shaving can lead to ingrowns, as waxing and rotary de-epilators (the worst) do.
As much as I don’t want to mention, you’re going to find your experience by far the exception. 10% of hairs ingowing is a full-on medical condition. Even when I was starting out and barely managing my technique, I still was nowhere near that level of ingrowns or skin irritation, nowhere near it.
Now about laser, that’s a different story. I totally regret getting laser. But then again, I was treated with a laser (diode) that also combined the pulse with high-frequency radio waves (like a micro-wave) to pre-heat the follical (yes it hurt like h**l), and I don’t think they are even used anymore, but then again, I don’t keep up on the industry.
I can see why you favor shaving, in actuality, it is probably best for you individually, but for a long time, a really long time, electrolysis has been the answer for many.
Take care
A light covering of calamine lotion might help you see them more easily
