Does Hair Stop Growing at a Certain Length?

We can't all be Rapunzel. Everyone's hair is programmed to stop growing at a certain length.

A few lucky people might be able to grow Rapunzel-length locks. Witness Xie Quiping, the current Guinness Book of World Records holder for longest hair. In 1984, her hair measured over 5.6 metres long.

Ladder-length hair is out of reach for most people, but there's no one set point at which all human head hair stops growing. Instead, hair growth is the complex product of genetics, health, care, and even seasonal changes.

Except in very rare cases, everyone's hair stops growing at a personal set point. This point might change with time, age, and overall health, but there's little you can do to change your hair's set point for growth.



How Long Does Hair Typically Grow?

Everyone's hair is genetically programmed to stop growing at a specific length. When hair stops growing, it enters a resting phase, falls out, and eventually regrows. On average, a hair grows for two to seven years, so the ultimate length of any given hair strand depends on how quickly your hair grows.

Most people can expect about a half inch of growth each month. If your hair grows at this rate, you can expect a maximum hair length of 12 to 42 inches.

Some people have longer hair growth cycles. There's some evidence, for example, that people of Asian descent tend to grow hair more quickly or for longer periods—perhaps explaining why Quiping was able to grow her hair so long.

Factors Affecting Hair Growth

You can't change genetics, which set upper and lower parameters for hair growth, but a number of other factors can affect hair growth.

Scalp health: Infections dryness, and frequent irritation of the scalp can slow hair growth.

Hair follicle health: If your hair follicles are damaged, your hair will stop growing sooner and may not grow at all. Frequent hair-pulling can damage hair follicles.

Hair breakage and hair shaft health: With the exception of the area immediately surrounding the follicle, hair is made of dead cells. That means that a better diet, hair vitamins, and other factors won't improve the overall health of your visible hair. They'll only alter the hair follicle, potentially improving growth.

But an unhealthy hair shaft can still affect hair growth for one simple reason: damaged hair tends to break off more easily. Reduce breakage and improve shaft health with a hair oil such as the MOROCCANOIL Original Oil Treatment or try a serum to restore hair fibre Kérastase Résistance Extentioniste Serum 50ml.

Physical health: Your physiological health can affect the health of your hair follicles. A healthy diet rich in vitamins and nutrients improves follicle health, while nutritional deficits can slow hair growth. If you want to improve hair health from within, consider a biotin-based supplement such as Viviscal Maximum Strength Hair Supplement - 1 Month Supply

Age: Hair growth tends to slow with age, particularly as physical health tends to decline. You might also believe that your hair looks thinner now than it did when you were a child, but this is little more than an optical illusion. We're born with all the hair follicles we'll ever have, so apparent thinning is actually due to the scalp growing, resulting in a head less densely populated with hair.

Season: Hair tends to grow more quickly in warm, humid climates. Cold weather also dries out the hair shaft, making it break more easily. Remember: breakage makes hair look as if it's growing more slowly than it is.
