When you start a new regime, do you regrow or maintain first

[obstacle_1]

Im about to start a regime of the big 3,I was just wandering do you start them all at once? Or have a while to regrow hair and then maintain or the other way around? Its so confusing!

start them all at once...and you will have to use them all for the rest of your life or whatever gains youve made on them will be gone.
