Hair loss on pillow in morning. Is this normal? I do have a good amount of hair, currently. But concerned.

As of last week and half ... I've noticed in am , on pillow about 20-30 as of last few days , maybe even more hairs ( prior to this, have noticed around 12-to sometimes 20 , certainly, less as well at other times ) Only if thing I have changed in last couple weeks was a product listed below phyto phylum ( only used twice in one week ) almost noticed very minimal hairs on pillow in the morning after the first use then after the second use a couple days later seem to notice the significant more.
