Is it common to take stem cell scalp injections and hair loss medication together?

After looking into stem cell scalp injections, I became curious whether they are done alone or in combination with other treatments.

Does the results tend to be better when combined with hair loss medication or scalp care?

I'm also confused about whether stem cell scalp injections are intended to reduce hair shedding or improve hair thickness.

I would love to find a place that explains the treatment based on my current stage of hair loss during the consultation. ㅠㅠ

For those of you who have received stem cell scalp injections, did you also receive other treatments?
