My hair loss was really bad. Then I went to the health food store and bought a bag of raw pumpkin seeds.
They have no shells, so they were easy to eat...like sunflower seeds.
I had to eat 2 tablespoons every day.
My hair grew in really thick, but it was about 6 months before it was noticeable.
The seeds are high in zinc, but it could be other nutrients that help also.
And if you search for 'pumpkin seeds remedies' in the internet, you will find loads of health benefits besides hair loss.
They gave me a lot of energy and my back stopped itching too. And my dry skin went away.
