Well, sorry but I dont agree with you. In some extremely rare cases, excessive exercise without steroids can raise testosterone levels and lead to hair loss. Sweat buildup on the scalp can also cause hair to shed or just break and get dull and dry.
Do yoga, cleanse your scalp, take a cold shower, massage the scalp, brush your hair.
Rubbing fingernails against each other also proven helpful to increase blood flow to scalp and reduce hair loss.
