1/2 cup (125 ml) lemon juice
1 cup (250ml) warm water
When a flaky scalp is caused by a buildup of dry skin, the gentle effects of lemon can be just the right antidote. To use, mix together the lemon juice and warm water. Shampoo and rinse as usual, then pour the lemon water over your freshly washed hair, rubbing gently into the scalp. Leave on for a few minutes, then rinse thoroughly. Repeat weekly as needed. If oily hair is the only problem, dilute the mixture with an extra cup of water.
Use with caution as lemon juice may cause scalp irritation
Use with caution as lemon juice might discolor hair.
