“In women, hair loss or noticeable thinning of the hair often occurs when levels of the female hormone estrogen decline after menopause. “DHT affects hair follicles and seems to prolong the telogen (resting) phase.” 5) Sherrow, V. The body converts testosterone into the hormone DHT by way of an enzyme found in various tissues throughout the body…In men…DHT increases the resting (telogen) phase and decreases the growing (anagen) phase of hair.” 4) Rassman, W. “The cause of pattern thinning in men is primarily related to two sex hormones, testosterone and DHT. Here’s what some authorities specializing in hair biology say: Now that is a theologian’s perspective, but is that backed up scientifically? Since dermatology is not a field I’m an expert in, I had to do some digging and I found out that MacArthur is absolutely correct in his assessment. The female hormone estrogen causes the cycle to remain in stage one for a longer period, causing women’s hair to grow longer than men’s.” 3) MacArthur, John (2011). The male hormone testosterone speeds up the cycle so that men reach the third stage earlier than women. Head hair develops in three stages: formation and growth, resting, and fallout.
One obvious difference is the process of hair growth. “Men and women have distinctive physiologies. And this is exactly the case: women tend to stay in this phase longer than men. Obviously if one stays in the anagen (hair growth phase) for a longer time, they will have longer hair. I recommend you watch this short video to help you visualize and understand these three phases better:Īs mentioned our hormones play a significant role in how long we stay in a particular phase. Telogen – Resting or shedding phase (lasts about 3 months) However, our hormones are a major factor which can determine how long we stay in a particular phase.Īnagen – Hair growth phase (lasts 2-7 years)Ĭatagen – Transition phase (lasts about 10 days) Hair Loss and Balding: Causes, Symptoms & Treatments. So we keep cycling through the phases and each of the hairs on our head are in a different phase at any given time (with about 90% being in the growing phase).
Our hair grows and sheds in a three-stage process which keeps repeating itself. So the difference is not that women’s hair grows faster. Men and women’s hair grow at pretty much the same rate of about 1cm per month. First, I need to explain how our hair grows. Yes, there does seem to be a built-in biological process that causes women to have longer hair than men (generally speaking, of course). Is there a biological function that makes women have longer hair? In 1 Cor 11:14-15, Paul declares that “ nature” teaches us that men are to have short hair and women are to have long hair.
