Buhari new look in august after he returns

I think there may be some confusion here.

As far as I know, there is no credible information or evidence to suggest that President Muhammadu Buhari, the President of Nigeria, has undergone a significant transformation or makeover in August or at any other time.

It's possible that you may be referring to a different public figure or celebrity who has undergone a transformation or makeover. Could you please provide more context or clarify what you mean by "new look" and "after he returns"?
