Welcome to Gaia! ::

I don't even know if it's a good forum for that, I hope so. >.<

So yeah, every time I shave my legs the very next day they start to itch like crazy. Of course, after shaving I'm always using either a cream or some kind of aftershave product and I even tried to make peelings, but nothing helps. I really have to force myself not to scratch them, since in the past I often scratched them so much they turned into a bloody mess.
You might say "Just don't think about it and you won't notice" but really, it's bad enough that it prevents me from sleeping.
In the end I just stopped shaving, but yeah, I'm already 23 and never, even once in my life did I show my legs. I'd really like to wear a dress or shorts once in a while. ^^"
So, any advice? >.<

Yeah, I have problems with different perfumes in creams. Try using a lotion instead of aftershave or thick creams. Lotion is usually thinner and will be lighter on your skin. I found Jergens' Shea Butter works really well to moisturize your skin. And any lotion with Cocoa Butter in it.

Lucky me with blonde hairs that are almost invisible
Allergies, it sounds like
Ever try Veet or another bladeless razor (or in their words, razorless)?
Works nicely, and when used enough, can get to where you use it only once a month on stubble

This coming from a girl that rarely shaves...

ooooh I know exactly what to do for this!! I used to have this problem something awful! Okay, so all ya gotta do is shave with a relatively new and sharp razor in the shower with....(wait for it).....hair conditioner. Trust me. What it does is it soften the hair and skin that you are gonna shave off and leave the small little holey thingys (so sorry I cant remember what they are called) with a super soft area to like, have more hair grow out of. Added bonus, you don't really even need to put on lotion after because the conditioner does the exact same stuff! Whabam! Problem solved! Hope I helped!
