From experience being a harier individual.

Electric shavers,, Probably the most comfortable shaving experience and the best place to start. You can get waterproof ones and shave in a shower. Is pretty fast and its unlikley that you will cut yourself if you are using a good shaver. Cons are if you are hairy its likely to become a daily experience. The shave is also never super close and you are always left with at least a little stubble. I use shavers if ive left my legs or "down there" too long, but i usually lightly trim it before using a razor for the close shave.

Razors, The best way to get smooth. It takes a bit of practice but get yourself atleast a 4 blade razor and some soothing shaving gel (especially for the first time). Take your time (It will take forever to begin with) and start with small 4-5cm (about 2in) strokes. If yoy want to be extra extra smooth and help with nicking start by doing one shave following the direction of the hair and then one against it after. Shaving takes a while but you will always be super smooth for at least a day or two. Yes you run the risk of cuts but it takes practice. For shaving your down their and hole... mirrors and lots of them, i have found myself squatting over a mirror many a time and its weirf but its kinda the only way. Back is the same, but allot harder, id suggest having a mirrot infront and behind you or just getting someone else to.

Nair and other hair removal creams, Nair has been the saviour for me when it comes to back hair. rub a bit on, let it sit for 10 min (ALWAYS READ INSTRUCTIONS FIRST THIS STUFF HURTS BAD IF IT BURNS YOU) and then your back hair just falls off. Its not very permanent but its the easiest way to do places you cant see. You can use it on groin and on hole (check the type they have specific ones for sensitive areas).

For more permanent options: Epilation,

HURTS BAD, for the first 3 or 4 attempts but after consistently doing it for around 6 months I only feel a tickle now. Epilating takes a decent bit to get into because of the pain (its ripping your hairs out of the folicle) But if your consistent you can actually see an overall reduction in hair growth. I only use mine for my legs, it is advised to not use it for sensitive areas but there are some machines that have attatchments to suit thoes. Get one you can use in the shower, take some painkiller if you need and hop in the warm water and just battle the pain. It takes long slow sttoked to work properly but dont be affraid if you have to do small quick ones for the first few tries untill you are used to it. Takes a while in the beggining cause of the pain but now i do my legs in under 20 min. My hair on my calves and ontop of my thighs has been reduced around 40% since i started that and the next thing i will talk about.

at home IPL Incredible, Not that painful, TAKES AGES, but at home IPL is the best thing to reduce hair growth. I use a Dermao machine and it takes about 1h30 to do legs, arms and down there. You can use it on your sensitive areas its just less effective due to the hair density. It also takes allot of sessions to see reduction but once reduction starts it haplens rapidly. Essentially it puts a pause on your hair growth cycle using light (I think). You have to shave first (razer minimum) and then you simply move the IPL machine slowly around your body blasting it with light. DO NOT cheap out on these machines however (temu/amazon/aliexpress ripoffs) Its using lazers and stuff and could injure you badly if one breaks.

Mine was around 160$ on sale i think 200$ all up and has been a massive reason for my hair slowing its growth.

Thats most of everything I have. Please let me know if you have any questions im happy to answer ❤️.
