good evening, the repeated loss hair may be primarily due to hypothyroidism and mal nourishment. so kindly repeat his t3 t4 tsh levels and review with ur endocrinologist. also he needs to improve his nourshiment, so a good diet with controlled thyroid status will have his problem solved. and the cause for his hypothyroidism is also important. he has hypothyroidism but y ? that problem has to be tackled. so a detailed examination with the endocrinologist is very important.

hi,
thanks for consulting us.
As you have said your son is suffering from hypothyroidism for 3 years associated with hair loss.
One major cause of hair loss is problems with the thyroid. Normally, hair growth has three phases, the anagen phase, the catagen phase and the dormant phase. When a person suffers from hypothyroidism or hypothyroidism, the general mechanism of the hair growth process shuts down and loses balance. Thyroid malfunctions can force hair follicles to remain in the dormant phase for a longer period of time than normal. This leads to stalled hair growth and eventually hair loss.

The thyroid is an endocrine gland, which is located on both sides of the trachea. It secretes the thyroid hormone, known as thyroxin, which regulates the rate of the metabolism. Any disruption in the mechanism can have great impact on overall metabolic activities. Once the metabolism is disturbed, it has been found to cause a series of abnormalities, one being hair loss. Hair loss occurs when dihydrotestosterone (DHT) shrinks the hair follicles and eventually causes them to disappear. The problem of hypothyroidism and hyperthyroidism both encourage the conversion process of testosterone into DHT which accelerates hair loss in men and women.
1. Treat the hypothyroidism with thyroid hormone supplement drug. Maintain the level around the normal range. You should consult an Endocrinologist. take a second opinion if required.
2. The U.S. Food and Drug Administration (FDA) has approved only two medications for the treatment of male pattern baldness; these are minoxidil and finasteride. works by binding to 5-alpha-reductase, the enzyme responsible for the conversion of free testosterone to DHT.
3. Hair transplantation- is a good alternative choice. using small grafts of naturally-occurring units of one to four hairs, called follicular units, to move hair-producing follicles to balding areas of the hair restoration patient's scalp. These follicular units are surgically implanted in the scalp in very close proximity to one another and in large numbers. The grafts are obtained in one or both of the two primary methods of surgical extraction.
4. Laser therapy- There are devices that use low-level laser therapy (LLLT) that claim to stimulate hair growth through "photo-biostimulation" of the hair follicles.
So you may take this advanced option to treat it. Best of luck.
