Hello dear,
The case history as mentioned in your post indicate that the hair loss can be attributed to excessive application of dye & shampoo.
However, other causes of hair loss which needs to be concerned of are:
1. Environmental factors
2. Stress
3. Deficiency of certain minerals, vitamins & amino acids in diet. e.g. Iron, zinc, Vit B complex, lysine.
4.
Hormonal factors. e.g.
Thyroxine 5. Any incidence of surgery, shock, etc.
Management includes:
1. Treating the underlying cause
2. Avoidance of stress
3. Dietary modifications
4.
Minoxidil solution to be applied locally to stimulate the hair follicles
5.
Multivitamin & multi mineral supplementation
But these medications have to be used regularly under the guidance of a
Dermatologist, as hair loss tends to return on stoppage of these medications.
There is no need to worry.
Your hairs will grow back again.
Wishing you a Good Health.
Thanks & take care.
