One of the things that girls look for in a guy is whether or not they are healthy. Healthy guys will usually have healthy offspring so women are actually programmed to seek out men that take care of themselves.
With that in mind, I recommend going to the gym, eating well, use all natural products and if you can, use non-toxic cleaning products as well.
I personally try to keep everything as natural as possible, I get a ton of sleep and exercise every day. Overall, when I do this (and I’ll be honest, sometimes I go weeks without having a normal routine), I feel great and girls notice!
