This is an advice of a local actor who used to be a popular comedian. Laundry soap is best for the face and hair. Instead of shampoo, use the white soap bar which contains coconut oil (you have to check the label for that ingredient) and it will arrest the hair loss and also the whitening of hair. For the face, the white bar soap greatly helps in preventing acne. The laundry soap is way much cheaper than shampoo and regular soap. But to be honest, I only use the laundry bar soap twice a week because I love the scent of the shampoo and perfumed soap as well.
