There are a few different ways you can achieve this, one option would be to add the following line to the .htaccess file in your domains web-directory, or create the .htaccess file if it doesn’t already exist.
redirect 301 /index.html http://www.alertaesthetics.com/home/
Depending on exactly what it is you are trying to achieve, the easiest method may be to simply specify the web-directory for the domain to be alertaesthetics.com/home/ instead of alertaesthetics.com. This can be done in the panel by going to Domains -> Manage Domains, then clicking Edit under the Web Hosting column for the relevant domain. On the resulting page you can change the Specify your web directory: field, before clicking the Change fully hosted settings now button.
