The errori I get is...
Login.dm:15:error:usr.o.icon:undefined var

Why?
mob
    Login()
        o = new/obj/Hair
        overlays += o
    var
        o
obj
    Hair
        var/setting = "0,0,0"
        icon='Hair.dmi'
        layer=MOB_LAYER+1
        pixel_y=40
turf
    Buttons
        icon='Login.dmi'
        Left_22
            icon_state = "Left-2,2"
            Click()
                if(usr.o)
                    world<<"Checking Top_left"
                    usr.o.icon += rgb(0,20,20)
//                  usr.o.setting = "20,0,0"
                    world<<"Changing Hair Color!"
                if(usr.Hairoverlay == 0)
                    usr.Hairoverlay = 1

Where do you define "o"? Could you show that code?

In response to Strawgate
 
usr.o.icon


o doesn't have an icon try

usr.o += rgb(0,20,20)


I think that may work i don't see why not

turf
    Buttons
        icon='Login.dmi'
        Left_22
            icon_state = "Left-2,2"
            Click()
                world<<"Checking Top_left"
                usr.o += rgb(0,20,20)
//                  usr.o.setting = "20,0,0"
                world<<"Changing Hair Color!"

Output:

Use this;
mob/var/obj/o
...
var/obj/a = new/obj/hair
usr.o=a
