What kind of hair loss and scalp care do you do the most?

There are many treatments like scalp stem cell therapy CureJet, but I'm wondering if it's feasible to consistently receive treatments while working. Please recommend some hair loss scalp care that's manageable for someone with a busy job.

There's a lot of talk about needing to improve scalp condition fundamentally for hair loss treatments to be effective, so I've been researching various options lately.

If anyone knows of hair loss scalp care with minimal downtime, please share!
