Is it ok to upload hair pictures and videos only?

I make hair related content, where i share haircare/ growth tips for which i have to show my hair only so that audience can rely on my techniques and sometimes i have to show tutorials for certain hairstyles. But i dont show my face, so is it still haram? Because as long as I know hair itself is not a sexual part, and i am not showing my face , so nobody can have a slightest image of who i am. Because i am thinking to expand it as my hair brand but i am very confused that should I continue or not
