How Efficient Are Hair Masks, Hair Loss Shampoos, and Oils in Preventing Hair Loss?

The mechanism which can prevent hair loss should reach the hair follicle. Such products have a little chance to reach the hair roots. Shampoos that we apply to wash our hair remain on the scalp for two minutes on average, and then we rinse our hair. The hair care products are rinsed away after we wash our hair and have no permeability. Particularly oils, conditioners, or greasy products that are applied on the scalp do not get through the scalp, and have limited efficiency in preventing hair loss.
