- Olive oil. Heat some extra virgin olive oil in the microwave for 10 seconds and apply to dry hair. Leave it on for about 10 minutes, and then shampoo.
- Flat beer. Be sure to use beer that has lost its zing, or else heat fresh beer and allow it to cool. Wash your hair, pour it on, and comb.
- Lemon juice. Wash hair and apply a tablespoon of lemon juice mixed with 2 ounces of strained liver. Wrap your head in a towel or wrap with plastic and sit under a warm dryer for 15 minutes. Rinse thoroughly.
- Vinegar. Cider vinegar is good for brunettes, white vinegar for blondes. Four tablespoons in three glasses of warm water. Then use lots of cool water to remove the salady smell.
- Lemons. Add juice of two lemons in two glasses of lukewarm water. If your hair does not tend to be dry, you can skip the rinse and let the sun add some highlights.
