What is the value of a conditioner in a person with hair loss?

I heard shampooing everyday isn’t good so I am trying to space it out more and do twice a week or so. However, on the off days, I plan to use conditioner but not sure which one. Does conditioner help with hair loss? I never proactively used it in the past so I am not sure. Also how long do you guys keep the shampoo and conditioner in for?

One of the problems that make hair loss of fragile hair worse, it combing and brushing hair that pulls out miniaturized or weak hairs early. The use of good conditioners, solves the pulling problem because the comb and the brush glide through the hairs with less pulling.
