The Stages of the Hair Growth Cycle Explained DiStefano Hair Restoration Center

It occurs during exogen and immediately transitions to hair regrowth or the anagen phase. New hair cells then start to multiply at the base of the “empty” hair follicle to form a new hair, and the growth phase of the hair growth cycle starts all over again. While many products do provide applicator nozzles that reach through the hair, some droppers aren’t as precise. The three stages of the hair growth cycle are the anagen, catagen, and telogen stages. Every guy’s hair grows (and falls out) at different rates, but everyone goes through the same stages.
The Catagen Transition Phase
The dermal papillaAt the base of the bulb is a group of cells called the dermal papilla. It provides a constant blood supply to the developing hair during active growth. It also facilitates cell-to-cell communication within the hair follicle (Chen et al., 2020). The bulge is located at roughly the halfway point between the upper and lower parts of the hair follicle.These stem cells eventually become part of either the outer hair bulb or inner hair shaft. Over time, the cuticle and nearby outer layers fill with keratin which is the protein which gives hair strength and flexibility.A structure called the outer sheath surrounds the entire bulb.

White club-shaped bulbs form on the now inactive ends of hair follicles. The hair growth cycle involves several phases that result in those sought after healthy, lustrous locks. However, hair loss can result when hair is cut off from the nourishment of blood vessels, or due to underlying conditions. This action signals the hair strands to stop growing, which transitions the hair to what is called “club hair.” Club hairs contain a bulb of keratin at the tip of the hair strand’s root. This bulb helps keep the hair shaft inside the follicle until it eventually sheds in the next phase. For instance, around 12 weeks after restrictive dieting or a high fever, you may experience telogen effluvium (sudden diffuse hair fall).
How Does Hair Loss Treatment Affect These Stages?
It is surrounded by the hair follicle (a sheath of skin and connective tissue), which is also connected to a sebaceous gland. The anagen (growth) stage of the cycle can last anywhere between 2-7 years before transitioning to the catagen and telogen stages. The Kiierr Laser Cap comes with the hair growth bundle, including shampoo, conditioner and vitamins, all of which have been specially formulated to help your scalp regrow its own natural hair.
The exogen (shedding) phase
When one phase in the process is disturbed, it may cause hair loss. The hair growth cycle is a coordinated process that consists of three primary stages. It helps ensure the proper growth and development of mature hair strands and the continued production of new hairs.

Meanwhile, cupuacu, murumuru, and tucuma butters provide a burst of hydration, giving strands the strength to grow longer and healthier. If you feel like your hair never grows, you may be wondering how fast does hair grow.
Let’s take a closer look at those four stages, the timelines for each one, and why it’s really important for some of your hair to fall out throughout the process. At any given time, approximately 90 percent of the hairs on your head are in the anagen phase, contributing to the overall health and fullness of your hair. The body has different types of hair, including vellus hair and androgenic hair, each with its own type of cellular construction. This hair will usually grow to several feet before terminating, but many humans develop much longer hair. However, lots of different factors affect the speed of hair growth. The germinal matrix, which is also referred to as the "matrix," is where cells produce new hairs as hairs die and fall out.
The anagen phase in normal scalp hair follicles lasts approximately two to six years, whereas eyebrow hairs last about 70 days in the anagen phase. During the telogen phase of the hair cycle, the resting hair remains in the follicle until it is pushed out by the growth of a new anagen hair. The telogen phase lasts for about five to six weeks for hairs on the scalp and much longer for hairs on the eyebrow, eyelash, arm, and leg. The hair growth cycle consists of three main phases – anagen (growth), catagen (transition), and telogen (resting) – each with its own stages that eventually lead to the shedding of the hair and replacement with new hair. To understand human hair growth, let’s discuss its physiology. The keratinous part of your hair that you see, comb, and style every day is called the hair shaft, with hair follicles located just inside the scalp.
This phase is primarily characterized by hair shedding from the scalp, often facilitated by washing and brushing. At any given time, only about 5 percent of the hairs on your head are in the catagen phase. We offer transplantation methods, including Follicular Unit Extraction (FUE) and Follicular Unit Transfer (FUT). Both involve moving healthy hairs from the donor site and planting them in problem areas. You can help keep your hair healthy by taking care of your overall health.
Just as with skin care, committing to a scientifically proven routine is the real secret to transforming the health of both your scalp and your hair for the long run. Telogen effluvium occurs when stress prompts the hair roots to enter the telogen stage of the hair cycle too early. It can mean that as many as 70% of scalp hairs fall out within about 2 months. The bulb of a hair follicle is under the skin at the bottom of a strand of hair. It is how blood gets to the hair to nourish it and help it grow.
Yoga, meditation, maintaining a healthy work-life balance, and getting enough sleep are all things that can help with this. Protein makes up a large proportion of your hair, so ensuring you’re getting enough in your diet can support optimal growth in the anagen stage. Eggs, nuts, meat, and beans are excellent protein sources to add to your meals. On average, hair tends to grow between 0.5 and 1.7 centimeters per month.
A piece of hair may look simple, but it’s one of the body's most complicated structures. The hair follicle is the part below the skin, and the hair shaft is what you see above your skin. The telogen phase of the hair cylce is just one point in a complex process of hair growth on your body. Around 5% to 10% percent of all your hairs are in the telogen phase at any given moment. Behind every noticeable hair change, there’s the subtle world of these hair growth phases at play.
Humans shed anywhere from 50 to 100 scalp hairs a day, but stress can cause a noticeable amount of hair loss. Eventually, the number of hair follicles in the telogen state increases while fewer hair follicles are growing hair. The effect is a progressive and overall thinning of the hair without much noticeable shedding. You may not think about how fast your hair grows until it’s time to get a haircut.
