Journal club of the week: hair growth, loss and therapeutics

 Speaker: Dr saeideh momtaz (postdoc student)

Topic:hair growth, loss and therapeutics

 

In the 1st February, 2016 journal meeting, Dr Saeideh Momtaz (Postdoc student) introduced the participants to hair growth, loss and therapeutics. First she discussed about hair specific growth cycle with three distinct and concurrent phases: anagen, catagen and telogen phases. Each phase has specific characteristics that determine the length of the hair. All three phases occur simultaneously; one strand of hair may be in the anagen phase, while another is in the telogen phase. Then she talked about different growth inhibitors and disorders related to hair like chemotherapy, alopecia-related syndromes, radiation therapy and UV-B. Most chemotherapy drugs work by attacking fast-replicating cells. Rapid cell replication is one of the hallmarks of cancer; however, hair follicle cells also grow and divide quickly. Consequently, the chemotherapy drugs usually inhibit hair growth. The dose and type of medicine determine the severity of hair loss, but once the chemotherapy has ended, new hair growth may begin after three to 10 months. Human hair follicles are very sensitive to the effects of radiation therapy administered to the head, most commonly used to treat cancerous growths within the brain. At the end she talked about some herbal medication which are helpful in hair growth and occurrences such as apple, Persia Americana, Onion, Lavender and etc.Approved hair-growth stimulants are Minoxidil and Finesteride that decrease release of DHT. She also briefly described how androgenic factors lead to hair loss. At the end all participants asked their valuable questions and she answered all the questions. At last but not the least Prof. Abdollahi summarized the topic.
