The Science Of Hair Growth

Updated on 18 June 2023

Hair growth is a marvel of biological complexity, influenced by a myriad of factors ranging from genetics to lifestyle. To combat hair fall effectively, it's imperative to comprehend the intricate science that governs this natural process.

In this blog post, we'll unravel the science behind hair growth and explore potential remedies as hair fall cure based on this understanding.

Hair Growth: A Cyclical Journey

The hair growth cycle is composed of three primary phases: anagen, catagen, and telogen.

Anagen Phase

During this phase, the hair follicles are actively growing. The cells in the hair root divide rapidly, leading to the development of a new hair shaft. This stage can last anywhere from 2 to 7 years, and it significantly determines the length of your hair.

Catagen Phase

The catagen phase serves as a transitional period, where hair growth halts. The hair follicles shrink and detach from the blood supply, preparing for the next phase.

Telogen Phase

The telogen phase is the resting period where the old hair detaches from the follicle but remains in place. Approximately 10-15% of hairs are in this phase, which lasts around 3 to 4 months.

Understanding this cycle helps us grasp the correlation between hair fall and hair growth.

Factors Influencing Hair Growth

Several factors impact the hair growth cycle:

Genetics

Genetics significantly dictate your hair growth patterns, hair type, and vulnerability to hair fall. If hair loss is prevalent in your family, you are more likely to experience it too.

Hormonal Fluctuations

Hormonal imbalances, especially changes in androgen levels like testosterone, can influence hair growth. Conditions such as polycystic ovary syndrome (PCOS) and menopause can lead to hair fall due to these hormonal shifts.

Nutritional Intake

A balanced diet rich in vitamins, minerals, and proteins is crucial for healthy hair growth. Nutrient deficiencies can weaken hair strands and contribute to increased hair fall.

Health Conditions

Various health conditions and chronic illnesses can impact hair growth and result in hair fall. Conditions like thyroid disorders and autoimmune diseases may lead to hair loss.

Hair Fall Cure: Exploring Solutions

Addressing hair fall involves tackling its underlying causes. Here are potential remedies for hair fall backed by scientific understanding:

Balanced Diet

Prioritise a diet abundant in essential vitamins (A, B, C, D, and E), minerals (iron, zinc, and selenium), and proteins. These nutrients are pivotal in promoting healthy hair growth and reducing hair fall.

Scalp Health

A clean, well-moisturised, and unclogged scalp is crucial for hair growth. Regularly cleanse your scalp, keep it well-moisturised, and ensure good blood circulation through scalp massages.

Hair Care Routine

Tailor your hair care routine to suit your hair type and needs. Utilise mild shampoos or cleansers, conditioners, and minimise exposure to harsh chemicals or excessive heat, which can weaken hair.

Medical Interventions

In cases of severe hair fall, consult a dermatologist for potential medical treatments.

Lifestyle Modifications

Adopt a healthy lifestyle by engaging in regular physical activity, maintaining sufficient sleep, and practising stress-reduction techniques. Stress can exacerbate hair fall, so managing it is pivotal.

Understanding the science of hair growth is key to combating hair fall effectively. While genetics and hormonal factors play significant roles, maintaining a balanced diet, adhering to a suitable hair care routine, and seeking expert guidance when necessary can help combat hair fall.
