Yes baking soda does help prevent hair loss and help regrow hair that has already been lost.
Baking soda can be used to clean your hair naturally and keep the hair healthy as well.
Baking soda also helps to remove any leftover residue from other hair products you might have used as well.
Take some baking soda and mix it with water using a 1 to 3 ratio to make baking soda shampoo.
A small squeeze bottle works great for adding the baking soda shampoo to your hair or you can just use an empty soda bottle or water bottle to mix the baking soda and water together.
After washing your hair with baking soda and water take some apple cider vinegar and pour some over your hair and massage it in and then rinse it out.
Using both apple cider vinegar and baking soda will help to add even more shine to your hair and prevent hair loss and regrow any lost hair.
It worked great for me and still works for me.
