Hydration=Aqua. Aqua or water is the first step here. Drink lots as well as spray on to your hair with a few drops of rosemary essential oil. Also a weekly egg and oil pack. Never shampoo after egg pack, instead wash with cold water which has a few drops of lime drops in it. Sufficiently gets rid of the eggy smell and the shampoo is not required (shampoo will strip all good done by the eggs).
