yes you can use gel but when the gel dries, the wet look is gone.

you need to use hair products fortified with shine enhancing ingredients.

maybe you need more than one product to achieve the perfect wet look.

fudge,redke, loreal profesional series make really good wet look/shiny look hair product.

check out your local salon to see what they use for styling wet look.

wut i used to do was wet my hair fist, dry it a bit so that its not dripping, then apply the gel. it will make ur hair look wet. if its not "wet" looking enough, just wet ur hands very little at a time and run your fingers through.
