Can flaky scalp cause hair loss?

[Jane123]

I've been going through hair loss for a while. I've been told it's hormonal, but lately I've been thinking there might be another problem- When I run my fingers brought my scalp to massage it (with oils) at night, hairs often part with my scalp. They have a flaky piece of the scalp root or something attached. Is the dandruff making my hair unable to grow properly and his fall out easily? Or is it just a side effect of a bigger cause?
