3. Avocado + Mayonnaise
This is a really good deep treatment for hair, as it helps to restore moisture.
Peel and mash up an avocado, and mix it with one cup of regular mayonnaise. Apply it to your hair; put on a shower cap or wrap your head up with plastic wrap. That will trap heat and help the mixture penetrate more.
Shampoo as usual; remember, you don’t need to condition afterwards. Your hair will be soft and shiny.
