Ah yon ay normal lang yan sa newborns, marami sa amin ang dumaan dito, usually it's just the baby hair shedding na part ng development, kaya don't worry too much! Cetaphil is actually gentle which is good, pero kung gusto mo ng something mas specific for baby hair, you could try looking into baby shampoos na gentler pa or consult with your pedia kung concerned ka na talaga about the amount of shedding, they can check kung may underlying concern. One of my mum friends says maganda rin ang consistency, like regular shampooing at gentle massage lang while bathing, and the shedding usually slows down as they get older na.
