Introduction to Hair & Scalp
- Humans have an average of 100000 strands (Gray, 2003).
- Each hair strand can grow 3-6 years normally. Cross section of Hair & Scalp Image courtesy jesharrington87
- The hair grows through a protective tube called follicle in the dermis layer. Hair forms at the bottom of the follicle, known as the dermal papilla.
- Sebaceous glands (oil glands) produce an oily substance to lubricate the hair and scalp.
- Sweat glands excrete salty and acidic compounds produced by the scalp.
Hair Growth Cycle
The Hair Regeneration Cycle is a natural process that occurs in the hair follicles. This cycle consists of three main phases: Anagen, Catagen, and Telogen. During the Anagen phase, the hair grows actively, while in the Catagen phase, the hair stops growing and prepares to shed. Finally, in the Telogen phase, the hair falls out and the cycle starts again.
Understanding the Hair Regeneration Cycle is crucial for maintaining healthy hair and preventing hair loss. By knowing the different phases of the cycle, individuals can take steps to promote hair growth and maintain a full, healthy head of hair.
In conclusion, the Hair Regeneration Cycle is a complex process that plays a significant role in the health and appearance of our hair. By understanding and caring for our hair properly, we can ensure that it remains strong, vibrant, and beautiful.

Anagen-Growth Phase that lasts for 3-6 years, approximately 85-90% of all hairs in this stage, typically hair grows 1-1.5cm per month.
Catagen – Transitional Phase takes only 1 – 3 weeks, the follicle shrinks to about 1/6 of average length, and the hair stops growing.
Telogen – Resting Phase last about three months, about 10-15% of all hairs in this stage, the hair does not grow and come off.
Anagen Onset– Return to Anagen Phase – New hair strand starts to form and grow.
Exogen/ Early Anagen– Shedding old hair and developing new hair.
Regeneration cycle: Each follicle can produce about 20 individual hairs in a person’s lifetime.
Hair and Scalp: Causes of Problems
One of the main factors that can lead to hair and scalp issues is the accumulation of excessive sebum/oil and product buildups. This buildup can slow down circulation, limiting the nutrient supply and absorption in the scalp.
When pores become clogged with sebum/oil and buildup, it can cause inflammation of the scalp due to microbial infections. Additionally, clogged pores can affect the oil glands in follicles, resulting in an imbalance of sebum secretion. This can worsen the scalp condition, leading to further inflammation and abnormalities in function that accelerate the follicles into the telogen phase faster.
On the other hand, excess testosterone present in sebum can be converted into a potent androgen called Dihydrotestosterone (DHT) by an enzyme called 5αR in the hair follicle. DHT can affect the cell proliferation of the matrix, causing weaker hair roots with a shorter lifespan.
As most hairs enter the resting stage (telogen), the hair metabolism becomes destabilized, resulting in thinner and sparser hair. Weak hair only remains for a couple of weeks, as hair roots only have around 20 regeneration cycles. Once the regeneration cycle is over, the hair roots become dead, making it impossible for hair to regrow.
In addition to sebum buildup, there are other factors that can trigger hair loss, including stress levels, scalp hygiene, hormone imbalances, poor diet, environmental pollution, overall health, medication, genetic factors, and more. It is important to address these factors in order to maintain a healthy scalp and promote hair growth.
Low iron levels can stem from various factors beyond inadequate dietary intake. Here are eight often overlooked root causes of iron deficiency:
- Chronic Inflammation & Anemia of Chronic Disease
Inflammation can hinder iron absorption and impede the body’s utilization of stored iron. Autoimmune diseases, infections, and cancer are among the conditions that can exacerbate this issue. - Gut Microbiome Imbalance
Certain gut bacteria and pathogens consume iron, rendering it inaccessible for absorption. An imbalanced microbiome can also hinder iron uptake. - Copper Deficiency
Copper plays a crucial role in iron metabolism. Insufficient copper levels can impede the proper transport and utilization of iron in the body. - Excessive Coffee, Tea, or Dairy Consumption
Compounds like tannins (found in tea and coffee) and calcium (present in dairy) can inhibit iron absorption, particularly when consumed in close proximity to meals or iron supplements. - Heavy Menstrual Bleeding
Excessive menstrual bleeding is a significant contributor to iron loss in women, leading to chronic deficiency. - Malabsorption Conditions
Conditions such as celiac disease, Crohn’s disease, and bariatric surgery can diminish iron absorption in the intestines. - Hidden Loss
Conditions like ulcers, colon polyps, or gastrointestinal bleeding can result in gradual, unnoticed iron loss, ultimately leading to deficiency. - Increased Iron Demand
Pregnancy, rapid growth in children, and intense physical activity can elevate iron requirements, potentially resulting in deficiency if intake is insufficient.
To optimize your body’s natural iron absorption, consider scheduling a wellness check. This simple step can help ensure that you are getting the most out of your dietary iron intake.
