Nair for men

I have used nair before and i thought by purchasing nair for men it would be a better product for me becuase the nair the original formula removed almost all of my body hair except for my chest area, i had the money and time so i finally went to my local drugstore and purchased it. I gor home and headed directly to the bathroom, I applied it to my entire body from legs to chest and waited at least 10 minutes the maximum allowed by nair as I started to remove the lotion in the shower I saw spatches of hair that weren't removed (eww) by the product and then felt this itching and burning sensation on my chest, my chest felt like it had open sores,and it didn't go away for about a week. it was probably one of the worst experiences I have had with nair but since then I never used nair for men. I only use nair the original formula and the baby oil lotion.
