How Many Hair Cycles In the Life of a Hair?

Hi doctor and a big thanks to you and your team. Im very interested to know at least to tell me how many hair cycles there are. i read somewhere there are 14 in another place there are 25-30 and i like to know not the exact number but for something close. where is the truth because i have been doing a little experiment. i had a single hair divided from the others, i mean theres not another hairs around this one and it keeps falling and falling and it has surpassed the number 20 of cycle and it keeps showing after some months before being full mature it will fall off again and im so confused. pls help. i will be glad for ur response and thank before very very much

The answer is not so simple. If you average 4 years for a cycle and there are 30 cycles per human (as an example) that would mean that your hair will last 120 years. Unfortunately, our cycles get shorter as we get older. How much shorter depends upon your genetics, so you see, nothing I just said is solid enough to hang your hat on. We tend to preach that hair has a 3 year cycle, but how do we really know that? The answers are illusive. Sorry!
