Collagen + biotin gummies

Will gummies that has both collagen and biotin help thicken and regrow my hair and reduce hair fall? If not by themselves, what about in addition with scalp massage?

Does hair loss/hair thinning cause determine whether or not the gummies work?

Does anyone have any experience and success with these kind of gummies?

I don't know what the cause of my hair fall/hair thinning is, although my mom says it's genetic. I haven't been diagnosed with any type of hair loss since I haven't seen a specialist or brought up the topic to my family doctor.
