Answer first
A practical routine for working men: wash daily or every other day with a mild shampoo, massage with fingertips for a minute, rinse well, dry the roots, and go easy on heavy styling products. Take monthly photos in the same light to track any thinning.
Morning or night
Wash when it suits you, but do not sleep on damp hair. After a sweaty commute or helmet ride, a rinse helps.
Tracking
Monthly photos of your hairline and crown are more reliable than the mirror. Bring them to a scalp check.
Questions
Is hair gel bad?
Not by itself. Wash it out properly.
When should I get a check?
If you see thinning in photos over a few months.
