Natural hair straightening products: 2 eggs + 1–2 spoons of olive oil. Apply the mixture thoroughly on your hair. Leave it on for a few hours, then shampoo. Milk + honey. Keep it on for at least 1 to 2 hours, and wash it off with a gentle shampoo.
To straighten hair without heat, just mix a cup of water with 2 tablespoons of BROWN sugar, pour it into a spray bottle, then spray into damp hair and let air dry. (I think I already pinned this,but you can never be too sure! lol)
