How Long Does It Take for a Hair to Fully Mature from the Time It Sprouts after Hair Transplant Surgery?
Approximately how long does it take for a single hair to fully mature from the day it sprouts out of the skin, to the day it has fully matured. Are we talking 4 weeks or so, or many months?
Interesting question. So you’re asking: How long does it take for a single hair to fully mature from the day it sprouts to the day it’s fully matured? I’ll start by giving you my favorite answer in all of medicine: it depends. Annoying, right? But please, do read on …
So let’s take a step back and look not at the hairs maturing, but the follicles that produce the hairs maturing — and how this affects the maturation of the hair.
There is a specific reason why most transplanted follicles don’t start growing hair until 3 months after surgical hair restoration. When follicles “rest” and don’t grow hair, they are said to be in the “telogen” phase. Basically, follicles stop functioning in this stage and don’t produce hairs. Telogen can occur for a variety of reasons: as part of a normal hair cycle, as the permanent end result of androgenic alopecia, or as part of post-surgical trauma. But regardless of why it happens, it usually lasts 3-4 months.
