Query: What a bummer!

I got this product but didn't use it and kept it in a drawer for a year or two. When my electric razor broke, I decided to try it. I have weird allergies and usually react to stuff marked hypoallergenic, so I was nervous about using this brand because I can't use Sally Hansen makeup. However, I was pleased to find out that this might be the ONLY hair remover that I'm not allergic to. I'm so glad I found it because of that.However, here's the problem. The can was only enough to do my calves and my pits. Yes, I accidentally sprayed some on my bathroom wall, but still, that's not very much. What's worse is I used it on Thursday night and by Monday morning I had noticeable hair growth again. At first I thought this might just be because I left it sitting too long, but after reading all the other reviews, I now know that's not the answer.So, basically, this is a nice product because I'm not allergic to it, but there's not enough and it doesn't even last all that long. Quite a bummer.
