I tried a lot of times, but I think I've never had good results.
BUT: It's a SFW clip, so I can try it with kling
I upload a pic with the next:
first person view of a man. He gently grabs her scrunchie and pulls out displaying all her thick long hair
So, I let deepseek to finish the prompt, using the pic uploaded also.
From the man's viewpoint, hands carefully pull the white scrunchie from the ponytail. The woman's dense brown hair tumbles down her back in slow motion, individual strands catching soft light as the camera pushes in slightly to emphasize the hair's volume and movement within the minimalist white environment.
And that's the results. The first video, the first prompt. And next.
IMHO Kling is the best for SFW
