Treatment Options Available at Dr. Health Clinic

Hypothyroidism is managed by replacing the amount of hormone that your thyroid gland is no more making. This is done through medications. Consulting endocrinologists will help you arrive at the right treatment for your symptoms. 


  • Hypothyroidism reduces overflow blood flow and thus reduces the supply to the hair follicles causing hair loss. PRP is an advanced treatment for hair loss in which blood is extracted from the patient’s own body and put in a centrifuge. In this process, the activated platelets are separated from plasma, which is then injected into the affected areas of the scalp. This helps in the restoration and regrowth of the hair.
  • It’s important that you keep track of your symptoms, get regular thyroid checkups, and consult a doctor every single month. Ask for other possible management if hair loss continues even after medical treatment.
  • With proper management, hair growth may be noticeable within a few months.

In addition to thyroid disorders make sure you diagnose other conditions associated with hair loss.

Other conditions include. 

  • Family history(hereditary)
  • Medications and supplements. Hair loss can be a side effect of certain drugs, such as those used for arthritis, depression, cancer, and heart problems.
  • Stressful lifestyle. Noticed in people with highly stressful jobs. Increased stress leads to higher cortisol levels. Exercising outdoors, and daily meditation can reduce cortisol levels. In these conditions hair Loss is temporary 
  • Consumption of alcohol and smoking for a long period can affect hair growth.

Lifestyle and Diet Modifications

  • Along with medications changes in lifestyle and diet can improve hair growth and slow down the process of hair loss.
  • A diet rich in protein could prevent hair loss as protein is the building block for hair.
  • A diet rich in iron can prevent hair loss as iron contains ferritin. Thyroid disorder can cause low ferritin levels. Patterned hair loss is associated with increased levels of cortisol. U can boost your iron levels through iron supplement which is pretty much available everywhere.
  • Try multivitamins with biotin. Biotin is absolutely essential and an important element of vitamin B.

  • Consume foods rich in calcium. 
  • Limit your intake of alcohol and caffeine. Both may cause an increased inflammatory response. Inflammation may worsen thyroid conditions.
