Mostly echoing what others said. Do not risk scarring for this, you will eventually regret it. Also, unless you have white / grey / platinum blonde hair or very dark skin, electrolysis shouldn't be the first line of permanent hair removal anyway. It is faster, cheaper and more efficient to start with laser and then eventually do electrolysis if you have ambitious goals like "never shaving again" - for things like not having a visible 5 o clock shadow anymore even after days without shaving, and having peachy smooth skin with a very casual, quick shave, laser is usually sufficient if done right.

Still a price issue if insurance doesn't cover it, but a lot less than electrolysis simply because the workload is sooo much lower. We're talking about 10 - 20 half hour sessions vs literally hundreds of hours. If you go for this, make sure that it's a diode or alexandrite laser and not some IPL scam and try to get input from trans patients who've been to that place, results vary a lot depending on the technician's skills. Watch out for red flags like technicians not covering up birthmarks before a session, no permanent reduction of hairs after more than a handful of sessions or people reporting that their hairs turned white instead of falling out.

The risk doesnt outweigh the benefit and youll end up with scarred skin. Laser works pretty good, electrolysis is obviously gold standard. But even a while with estrogen and waxing/epilating will calm your follicles if you cant afford laser/electrolysis

From my understanding, it's targeted destruction of follicle stem cells that stops hair growth, not scarring of the follicle. Off-the-shelf stuff isn't strong enough to do anything, and even if you could find alcohol or peroxide strong enough to have an effect, I'm not sure how you'd apply it without damaging your skin too. Esp peroxide which can cause tissue death at higher concentrations.

You can find some nut grass oil (Cyperus Rotundus) if you wanna try a topical. Results vary but some people swear by it.

I don't think you should do this. Waxing/epilating irritates your skin and applying peroxide (I'm assuming a commercial solution of hydrogen peroxide) can be damaging to the skin, doing it right after epilating is bad, you can damage your skin. Alcohol is not much of a problem, it is used in aftershave stuff, because it can actually help your skin heal as it is an antiseptic, but it will also make your skin dryer long term. Over all, this will probably not have the results you are after.
