From the wiki
A canonical explanation for the change was given in a two-part storyline on Star Trek: Enterprise. The two episodes, "Affliction" and "Divergence", aired in February 2005. An earlier story arc featured the Augments, genetically-engineered humans left over from the Eugenics Wars of the late 20th century, and who were defeated by Captain Jonathan Archer and the USS Enterprise in Klingon space. The Klingon High Council fears that Starfleet was developing armies of Augments; after gaining access to genetic material from the Augments, the Klingons perform experiments to increase their own intellect and strength. The experiments turn disastrous when a strain of flu one of the test subjects suffered from is mutated and becomes a deadly plague that spreads across the Empire, causing physical changes resulting in the afflicted bearing a TOS-era appearance. Dr. Phlox of the Enterprise formulates a cure for the virus, but the physical alterations remain in the populace and are inherited by offspring. Phlox indicated that "someday" the physical alterations could be reversed

...if you ignored the Temporal Cold War nonsense. Which made up most of the plotline.
