React router dom add headers and dashboard for certain routes

Question

I am using react router dom Version 5 in my react version 15 application, I want to know how I can display the page header and the dashboard in all the pages except the authentication and the sign up pages.

I tried to do a test on the pathname but I always had a lag when I change pages or when I try to disconnect, I have to refresh the page each time. Here's my code :

          <Router>
            {pathname !=='/' && pathname !== '/sign-in' && pathname !== '/sign-up' && 
              <>
                <Header></Header>
                <Dashboard ></Dashboard> 
              </>  
            }
          <Switch>
                <Route exact path='/' component={SignIn} />
                <Route path="/sign-in" component={SignIn} />
                <Route path="/sign-up" component={SignUp} />
                {
                  sessionStorage.getItem("token") === null ?
                  <Redirect  to='/sign-in'/>  :
                  <>
                  <Route path="/home" component={Home} />
                  <Route path="/management" component={Management} />
                  <Redirect  to='/home'/>  :

                </>
                }
                
          </Switch>
          </Router>

EDIT : I'm trying with render inside route tag ,It's worked fine. But, I would like to optimize my code :

          <Router>
          <Switch>
                <Route exact path='/' component={SignIn} />
                <Route path="/sign-in" component={SignIn} />
                <Route path="/sign-up" component={SignUp} />
                {
                  sessionStorage.getItem("token") === null ?
                  <Redirect  to='/sign-in'/>  :
                  <>
                  <Route path="/home" render={() =><> <Header/> 
                  <Dashboard/><Home/></>} />
                  <Route path="/management"  render={() =><> <Header/> 
                  <Dashboard /><Management/></>} />
                  <Redirect  to='/home'/>  :

                </>
                }
                
          </Switch>
          </Router>
