Using castor oil to prevent hair loss is a very easy as you don’t have to make a special formulation.Simply take some oil on your palm and work it through your hair from roots to tips in the same way apply your regular oil and massage well.Make sure not to use too much oil because it has thicker density and would be difficult to wash out.Let the oil sit in your hair for 15-20 minutes before rinsing with tepid water and shampoo.Alternatively, apply the oil before going to bed and leave overnight. Wash the hair next morning.To keep the oil staining your bed linen cover your head with a towel or any clean, cotton cloth.You can mix castor oil with any other stimulant oils such as peppermint before use for added effect.
