Hi Dianne Rose,
Based on your story, I can immediately pinpoint possible causes of your hair loss.
They are:
1. Scalp Dermatitis (inflammation of scalp)
2. Tinea Capitis (fungal infection of scalp)
3. Nutritional Deficiencies
4. Female Pattern Hair Loss(multi factorial causes)
Steroid scalp lotions, Ketoconazole shampoo and Minoxidil spray/foam will be your first line treatment.
The above treatments are not expensive. You have a medical condition and it’s turning into agoraphobia and possibly depression, so please please please seek a proper medical consult.
You should visit a doctor / dermatologist keen in treating hair loss.
