As a part of the cycle of hair resting, falling, and growing back again, shedding some hair everyday is considered quite normal. However, some people may experience more than normal hair loss, which can be due to a number of reasons. Prolonged illness, major surgery, certain medicines (such as anticoagulants, medicines for gout, medicines used for chemotherapy, excessive vitamin A supplements, birth control pills and antidepressants), fungal infections and stress may cause temporary hair loss, which can be rectified through proper treatment, or when one stops consuming the medicines that are causing hair loss. However, hormonal problems like the ones associated with the thyroid gland or imbalance of hormones may make hair loss severe and permanent, if not rectified.

Several women experience hair loss after pregnancy. Hair loss also occurs as a symptom of certain diseases such as diabetes or anemia; in such cases, the hair loss can be corrected or stopped by treating these diseases.

A clinic in America claims that excessive sebum is the single biggest cause of 99 per cent of all hair loss in men and women. Sebum tends to clog the pores of the scalp and hinders follicle growth. In time, the hair root is asphyxiated and it is impossible for new hair to grow.

Hair loss shampoos help in rectifying the problem of hair loss by providing proper nourishment and vital proteins and nutrients that food supplements may not provide. Check the label on the shampoo bottle to see what it contains. Proteins, keratin and amino acids all bond with the hair shaft to fill-in the cracks caused by poor treatment of the hair. They strengthen and protect the hair. Vitamin B5 or Panthenol has the ability to penetrate hair and is highly recommended for strength and healthy growth.

The type of shampoo that you use is purely one of personal choice. Cosmetic companies that produce shampoos spend millions of dollars on research and you can be sure that just about any shampoo will provide effective cleansing for your hair. However, you should try and identify the shampoo that suits your specific hair type. Each individuals hair is unique and what might work for others might not work for you.
