Make a mixture between one part of baking soda and three parts of water. Apply the resulting mixture to wet or dry hair and massage it well.
Let the mixture act for 2-3 min and then rinse it. Clean your hair from any remains by using warm water.
The next thing you should do is to make vinegar mixture by combining 1 part of apple cider vinegar and 4 parts of water. You can avoid the smell of ACV by adding a few drops of lavender, rosemary or peppermint oil. Wash your hair with this mixture.
It may be a little difficult to wash your hair without foam as the standard shampoos but the results will totally amaze and change your opinion!
