How much hair do you have? On average, people have approximately 100,000 hair follicles on their head. And while it’s common to lose between 50 and 100 strands of hair per day, those hairs eventually grow back. In fact, the average person’s hair grows about half an inch per month.
But have you ever wondered what exactly happens during the hair growth process? If so, you’re in luck! This comprehensive guide will teach you everything you need to know about the phases of hair growth.
So what are the phases of hair growth? Hair growth occurs in three distinct stages: the anagen phase, the catagen phase, and the telogen phase. Keep reading to learn more about each stage!
Anatomy of Hair
Hair is a complex and diverse subject. In order to understand the phases of hair growth, one must first understand the anatomy of hair. The hair shaft is composed of three layers: the medulla, cortex, and cuticle. The medulla is the innermost layer and is largely made up of keratin proteins. The cortex is the middle layer and consists of long, coiled keratin fibers. The cuticle is the outermost layer and consists of flattened keratin cells that overlap each other like shingles on a roof.
The hair bulb is the region at the base of the hair shaft where new cells are generated. Blood vessels in the bulb supply nutrients to these cells and promote cell growth. As new cells are generated, they push older cells up the shaft towards the surface of the skin. This process is known as Hair Growth Cycle or Anagen phase. It can last anywhere from 2 to 8 years.
After Anagen phase, comes Catagen phase which lasts for around 2-3 weeks. During this phase, hair follicle shrinks and attachment between bulb and dermal papilla weakens. Finally, Telogen phase begins which lasts for around 100 days. In this phase, hairs are shed naturally as new ones start growing from bulbs in Anagen phase again.
Phases of Hair Growth Cycle
Hair growth can be divided into three distinct phases: anagen, catagen, and telogen.
anagen: The anagen phase is the active growth phase of hair follicles. This phase can last for several years, during which time hairs grow longer and thicker.
catagen: The catagen phase is a brief transitional phase that marks the end of the anagen phase. Hairs enter the catagen phase when the cells in the hair bulb stop dividing. In thisphase, which lasts about 2-3 weeks, hairs will gradually detach from the blood supply and begin to move up the follicle towards the surface of the skin.
telogen: The telogen phase is the resting phase of hair growth. During this phase, which lasts about 2-4 months, hairs will remain in place on the scalp until they are eventually shed.
Factors Affecting the Hair Growth Cycle
The speed of hair growth is determined by a number of different factors. The growth phase, or anagen, can last anywhere from two to seven years, and is determined by genetics. The shorter the anagen phase, the shorter the overall length of hair that can be achieved.
The Catagen phase is a transitional period that lasts around 2-3 weeks, during which the hair follicle shrinks and the base of the bulb begins to detach from the dermal papilla.
The Telogen phase is a resting period that lasts around three months. During this time, the follicle remains dormant and no new hair growth occurs. Around 10-15% of all hairs are in this phase at any given time.
Finally, there is the Exogen phase, during which old hairs are shed to make way for new ones. This process happens continuously throughout our lives, with around 50-100 hairs being shed each day.
Common Hair Loss Disorders and Solutions
Hair loss can be a difficult thing to deal with, both emotionally and physically. There are many different disorders that can cause hair loss, and it can be hard to determine which one you may have. Below is a list of some of the most common hair loss disorders, as well as solutions for each.
Telogen Effluvium: This is a disorder that interrupts the growth cycle of your hair, causing it to fall out prematurely. The good news is, this is usually a temporary condition that will resolve itself over time. If you are concerned about the amount of hair you are losing, talk to your doctor. They may prescribe medication to help speed up the process.
Alopecia Areata: This disorder causes patches of hair loss on the scalp or other areas of the body. It is thought to be an autoimmune condition, where the body attacking its own healthy cells. There is no cure for alopecia areata, but there are treatments available that can help improve the appearance of affected areas. These include corticosteroid injections, topical immunotherapy, and light therapy.
Androgenetic Alopecia: This is the most common type of hair loss, affecting both men and women. It is caused by a combination of hormones and genetics, and typically leads to gradual thinning over time. While there is no cure for androgenetic alopecia, there are treatments available that can slow down or even halt hair loss. These include medications and laser therapy.
Scarring Alopecia: This hair loss disorder is caused by inflamed skin, which damages the follicles and prevents new hair from growing in. Treatment for scarring alopecia will depend on the underlying cause, such as an infection or an inflammatory disorder. In some cases, surgical treatments may be recommended to help restore lost hair.
No matter what type of hair loss disorder you are experiencing, it’s important to talk to your doctor about all your options for treatment. With the right diagnosis and treatment plan, most people can achieve a healthy head of hair again.
Tips for Maintaining Healthy Hair Growth
Your hair is in a continuous cycle of growth, rest, and shedding. Although it may seem like your hair doesn’t grow, it’s actually growing and shedding at the same time. Depending on the phase of hair growth, you may see different types of hair shedding.
Anagen: This is the active growing phase of hair follicles. Approximately 85-90% of your hair is in this phase at any given time. During this phase, hairs grow about 1 cm per month.
Catagen: This is the transitional phase of hair follicles where growth slows down and hairs begin to detach from the blood supply. This phase lasts about 2-3 weeks.
Telogen: This is the resting phase of hair follicles where hairs are released and new hairs begin to grow in their place. Approximately 10-15% of your hair is in this phase at any given time. This phase lasts about 100 days.
Here are some tips for maintaining healthy hair growth during each stage of the hair cycle:
– Eat a balanced diet rich in protein, vitamins, and minerals to support healthy cell growth
– Avoid hot tools and harsh chemicals that can damage or break your hair
– Keep your scalp clean and free from build-up to encourage healthy follicle turnover
– Get regular trims to keep split ends at bay and help prevent further breakage
– Protect your strands from sun damage by using a heat protectant spray or a UV-blocking hat
– Gentle scalp massage with essential oils can stimulate blood circulation to the hair follicles and promote new growth
– Use mild shampoos and gentle brushing techniques to prevent breakage
– Avoid tight hairstyles that can cause traction alopecia
– Avoid tight hairstyles that can cause tension on the scalp
