It is different. My hair thinned and I can clearly say the texture of my hair changed. I lost lots of my hair too.
It is a side effect of Accutane.
"According to WebMD, there are two types of hair loss induced by medications: telogen effluvium and Anagen effluvium. Typically, a healthy hair passes through two phases of growth: the anagen phase and telogen phase. The anagen phase is the period of continuous hair growth, and it lasts for three to four years. Following that it enters the telogen phase, which lasts about three months – a period of rest. At the end of the telogen phase, the hair falls out and is replaced by a new hair.
Telogen effluvium is the most common type of drug-induced hair loss. In this, the patient starts losing hair within two to four months after taking the drug. The drug causes the hair follicles to go to the telogen phase and fall out too early. Typically patients suffering from this type of hair loss shed 100t o 150 hairs a day.
Most common drugs that induce Telogen effluvium include Vitamin A drugs containing retinoids, antibiotic and antifungal drugs, antibiotics and antifungal drugs, antidepressants, birth control pills, epilepsy drugs, drugs that treat high cholesterol and high blood pressure, anti-clotting drugs, nonsteroidal anti-inflammatory drugs (NSAIDs), and Parkinson’s disease drugs." http://www.hairfear.com/hair-loss/21-understanding-drug-induced-hair-loss.htm
