What are the best oils for preventing hair loss in babies?

Dear, don’t worry. Hair loss is perfectly normal in babies during the first six months. As the hormone levels drop right after birth, this cause newborn to lose the hair he was born with. Later, after the first shed, your baby’s hair will enter into a new growth cycle and this time with healthy hairs :). I used coconut oil and almond oil on my baby's hair. Here is an useful article on baby's hair loss -- http://www.babycenter.com/0_hair-loss-in-babies_85.bc

your baby will naturally lose some significant amount of hair in the first few months. don't worry about it. however, i used to massage my babies' hair with virgin coconut oil, sweet almond oil, neem oil and even mustard oil. they both have nice thick hair now :)
