Potatoes are rich in vegetable starch, the same kind of chemical that is used in laundry to stiffen fibers. So, it stands to reason that potato juice could be used on your hair to provide a stiffening effect much like a hair gel.
I illustrated this effect with a simple experiment. I took a regular potato and chopped it up on a blender with a cup of water. This released the water-soluble starches in the potato which I then I filtered off and collected. The result was a cloudy, yellow solution. I then dipped a hair tress into this starch solution and let it dry over night.
You can highlight your gray hair with potato peels, the ultimate way to hide your grey hair and stay young. Boil potato peels in water. Stain this water and let it cool. Use this strained water as an after shampoo rinse, to darken your gray hair. Follow this religiously for every alternate hair wash for beautiful and natural highlighted hair.
