Hair today, gone tomorrow.

Aaron Taylor-Johnson shocked fans by shaving off his signature beard — and the “Bullet Train” star looks like a different person in a dramatic before-and-after pic he shared on his Instagram Story Thursday.

The 34-year-old actor shared side-by-side photos of himself revealing the transformation, writing “From one look…” over a snap of himself with long hair and a bushy beard and “…to another” on a new clean-faced selfie.

In the first photo, Taylor-Johnson rocked a thick beard and slicked-back hair that curled around his neck while wearing an unbuttoned pink linen shirt and aviator sunglasses.

His new look is quite a change, with the “Fall Guy” star sporting some light stubble in place of his full beard in the gym selfie.

Taylor-Johnson wore an orange tank top and the same charm necklace he wore in the first pic, showing off his much-shorter haircut as he posed in a mirror.

The “Anna Karenina” star — who is married to “Fifty Shades of Grey” director Sam Taylor-Johnson, 57 — is known for his long locks and facial hair, but this isn’t the first time he’s sported a more clean-shaven look.

He went beard-free while posing on the cover of GQ Mexico in May, and he also ditched his facial hair while walking the red carpet at the 2022 “Bullet Train” premiere with co-star Brad Pitt.

Perhaps the British actor is prepping for a new role, as rumors about Aaron being cast as the next James Bond have been flying in recent months.

In the meantime, fans can always enjoy his bearded look in “Kraven the Hunter,” hitting screens in December.
