How heavy is the fragrance ? Is it noticeable all say ? Does this come fragrance free ?

The fragrance in Verb Spray is very light. I barely notice it. I do not think it is available in fragrance-free but I am not positive on this.

Is this safe for color treated hair?

Yes. Safe for color-treated hair.

Has anyone tried this on men's hair? Looking for something that isn't going to look like my son put gel in his hair to keep it in place.

The Volume Dry Texture Spray works on all hair types! We recommend starting with a light layer all over the crown while massaging the scalp to boost body at the root. If you are looking for something with a stronger hold, we recommend looking into our hairsprays.

use before or after the curling iron?

I used it after the curling iron or styling brush. Spray it on to provide volume, finish fixing my hair with a brush & pick, then spray a bit of hair spray on for a final hold. My hair is slightly curly, so some days I can just blow dry & scrunch, spray the dry texture spray on to give volume, do the final fix with brush & hair pick, then hair spray lightly for final hold.
