Hair is a protein called keratin. Most people lose about 50-100 hair a day which that is normal, but if more is loss see a doctor. Hair loss is caused by many reasons. Some are as follow illness (cancer, lupus,diabetes etc.) ,or by taking medication, alopecia areata (disease), trichotillomania (pulling of the hair), poor nutrition (not enough minerals,vitamins,protein), hormonal problems or stress, infections of the scalp (fungal infections), hair treatments (damage done to the hair to fall out).
Most of the time it is hereditary, there are several other things that can contribute to it though





stress can play a major role in hair loss


illness or a major surgery


male-pattern baldness,


Certain infections


women notice hair loss about 3 months after they've had a baby


lack of circulation due to wearing a hat





If the papilla is destroyed hair will never grow out of that spot again.





Hope this helps
