Hair grows faster when you constantly cut it.
Myth.
Hair grows around half an inch a month, and cutting it won't speed up that process.
On average, we have around 120,000 hair follicles on our scalp, and they're all going through different phases of the hair growth cycle.
Correct.
So there's anagen, catagen, telogen, and exogen.
And right now on your scalp, generally up to 90% of hairs will be in the growth phase.
And then the rest are waiting to fall out.
And then some are shedding.
So hair is not going to grow faster if you cut it, but it will look nice if you get your trims regularly.
