There is an article somewhere on this site that lists that as a myth. The suds distribute, but plenty of people have build up on their scalp from not massaging product and oil off. You don't have be rough though. You should always be gentle with your scalp and hair.

I understand about being gentle though but I always thought it was emphasized that you have to massage your scalp well while cowashing. The thing is, when hair is wet it is easy to pull out... that's why it's easier and less painful to tweeze your eyebrows soon after a shower than when completely dry.

Taking your time and being thorough is different than being more intense. I have dry thin skin so too much exfoliating can actually rub skin off for me, which is a lot less superficial than just losing some hair. I am careful with all the skin on my body, except for the bottom of my feet .
