Why does Animal Hair Stop Growing?

Around the world, people keep pets as companions. Pets come in all shapes and sizes and each one has different needs.

In order to ensure that your pet stays healthy and happy, it’s important to understand everything about them – including why their hair stops growing.

What is Hair?

Hair is made of keratin, a type of protein. It grows in the follicles, which are small pockets in the skin that are surrounded by muscles, glands, and other tissues. Hair grows from the follicle’s bulb, which is deep in the skin.

As hair grows out of the follicle, it pushes older hair up and away, where it eventually falls off or is removed by brushing or washing. When the follicle lies dormant, no hair grows.

How Long Does Hair Grow?

Hair growth depends on several factors, including age and genetics. A newborn baby has an average of around 128,000 hairs on his or her head. By the time they reach adulthood, that number has dropped to about 100,000 – thanks largely to hair thinning.

For most people, hair growth is measured in centimeters. One centimeter is equal to about 0.3937 inches. So, on average, it takes more than two months for an adult’s hair to grow one centimeter long. However, this varies depending on the person and the type of hair they have.

Some people may need three or four months to grow one centimeter of hair while some may only need one month due to some factors including genetics and age.

Why Do Animals Have Hair That Never Stops Growing?

Some animals are able to produce an unlimited amount of fur because their bodies go through a special process called molting. This natural process allows old fur to fall off so that new fur can grow in.

Animals with molting fur include:

  • Whales and dolphins
  • Some smaller rodents like hamsters and guinea pigs

Molting occurs every few months to annually, depending on the type of animal it is, just as human hair tends to grow about half an inch each month.

During the molting process, animals will shed their entire coat within a period of just a couple of weeks. This allows them to have new sets of thicker coats for the upcoming winter season or warmer climates.

Once they are done shedding or have grown enough fur, they are able to keep these protective layers until it’s time again for molting season.

Hair Growth Cycle

Hair grows in cycles, which are split into three phases:

  • anagen – growth phase;
  • catagen – transitional phase; and
  • telogen – the resting phase.

Each strand of hair on the human head spends about three to four years in the anagen phase before it detaches and falls out. This is why people need to get their hair cut every few months.

Kittens spend nearly a year in the anagen phase while puppies take around two or three months to get through it. At any time, 10 percent of hairs are in transition while 50 percent of hairs are actually resting (telogen).

When your pet’s new hair comes in, some of the old hair is pushed out while some of it is retained. Feathers differ in that they remain in the anagen phase for around four to six weeks before entering the telogen phase, which lasts about three months

Stopping hair growth is advantageous to both humans and animals, though for different reasons. For example, if your pets had long tails or manes like wild animals do, these appendages could potentially get caught on branches.
