Waxy Substance Attached to Lost Hairs

Hello, i am a 21 yr old male who has been noticing hair loss for about 3 years. It is becoming evident now more then ever. My hair line is reciding and thining on top. One thing i have noticed is when i look at the hairs that have fallen out of my head there is always a tiny white/light yellowish waxy ball attached to the bottom of it. I also notice them in my hair. What could it be? I have talked to my doc about propecia and will probally start that.

thank you very much!

That little ball at the end is either the bulb of the hair, a normal part of the hair that is often present when it falls out, or a tiny plug of sebum (waxy protective substance produced by the hair follicle) which is also normal.

By the way, contrary to popular belief, plugging of the hair follicles by sebum, oil, or other substances is not the cause of genetic/male pattern hair loss. Often people think this because when they start to lose hair they also start to see the shininess of their scalp which was previously covered. You will be addressing one of the main causes of hair loss (DHT attacking and weakening the hair) by taking Propecia so that is a good first step.
