Searching for methods to stimulate hair growth? Grasping the critical role of hair growth hormones and discovering natural ways to enhance them is essential for lush, healthy locks. 

In this article, we delve into the science behind hair growth hormones, uncover their significant impact on hair health, and provide expert tips on naturally increasing their levels for better hair growth.

Understanding the hair growth cycle

Hair is a defining feature for many, reflecting not just personal style but also health and well-being. Its growth, however, is not a continuous stream but a cycle composed of three distinct phases: the anagen (growth phase), catagen (transitional phase), and telogen (resting phase). 

Understanding these phases is crucial for anyone looking to optimize hair growth and maintain healthy, vibrant locks.

Anagen phase (Growth Phase)

The anagen phase signifies the start of the hair growth cycle, marked by active cell division in the basal matrix of the hair follicle structure, fostering hair growth. This phase is crucial for hair growth, with the hair shaft lengthening as new cells are added at the root. 

Typically lasting between two to six years, especially on the scalp, the anagen phase determines the length and volume of hair. The duration of this phase varies greatly among individuals and is influenced by genetics, overall health, and nutritional status.

Catagen phase (Transitional Phase)

Following the anagen phase is the catagen phase, a transitional period where hair growth ceases, and the hair follicle begins to detach from the dermal blood supply. This phase signifies the end of active hair growth and prepares the hair follicle for renewal. 

Lasting around two to three weeks, the catagen phase involves the hair shaft being propelled upwards, and the hair follicle significantly shrinking as it transitions to the next stage of the hair growth cycle.

Telogen phase (Resting Phase)

The telogen phase, the concluding phase of the hair growth cycle, serves as a resting period, enabling the hair follicle to rejuvenate and prepare for new hair growth. Lasting about three to four months, this phase culminates in the natural shedding of hair, with an average of 25 to 100 hairs falling out daily. 

This process is a normal part of the cycle, making way for new hair growth as the cycle recommences. Despite the shedding, the majority of hair remains in the anagen phase, ensuring continuous hair growth and renewal.

Role of hormones in hair growth and loss

Hormones, including thyroid hormones, are critical regulators of hair growth and hair loss, playing a vital role within our body's complex systems. Their effects on hair health can be profound, dictating everything from hair density and texture to growth cycles. 

Understanding the impact of these hormones can help us better manage hair health and address issues related to hair loss or thinning. Let's explore the specific roles of various hormones in detail.


Estrogen, known for its vital role in female physiology, also acts as a significant promoter of hair growth. By extending the anagen phase, it encourages longer and denser hair growth. Estrogen contributes to increased follicle count, enhanced hair texture, and reduced hair shedding, making hair appear fuller and healthier. 

However, fluctuations in estrogen levels, such as those during pregnancy, postpartum, and menopause, can significantly affect hair health, leading to periods of enhanced growth or increased shedding.

Testosterone and Dihydrotestosterone 

Testosterone and its derivative, Dihydrotestosterone (DHT), are crucial hormones with profound effects on the human body, influencing everything from sexual development to hair growth and loss. 

While testosterone serves as the primary male sex hormone, playing key roles in developing male sexual characteristics, muscle and bone mass, and even affecting mood and red blood cell production, its impact on hair is quite complex. 

It promotes facial and body hair during puberty but paradoxically may lead to scalp hair loss in genetically predisposed individuals. This is due to its conversion into DHT by the enzyme 5-alpha reductase. 

DHT binds more strongly to androgen receptors in hair follicles, particularly those on the scalp, leading to the miniaturization of hair follicles, a shortened hair growth cycle, and eventually hair loss, a condition known as androgenetic alopecia. 

This dual impact of testosterone and DHT on promoting excessive hair growth and contributing to male patterned hair loss underscores the delicate balance hormones maintain in hair health, emphasizing the importance of understanding their roles within the body's endocrine system.

Treatments for hormone-related hair thinning

Hormonal hair thinning can be a challenging condition, but there are effective treatments available that can help manage and potentially reverse this type of hair loss. 

Whether the cause is an underlying health issue such as polycystic ovarian syndrome (PCOS) or hormonal changes from life stages like menopause, a blend of medical interventions and lifestyle modifications can alleviate hair thinning and stimulate hair growth.

Here are some of the most effective treatments for addressing hormone-related hair thinning:


hormones influence hair growth, hair cycle

An over-the-counter topical treatment that stimulates hair growth by enhancing blood flow to hair follicles and extending the anagen phase. Available in 2% and 5% solutions, it's suitable for both men and women experiencing androgenetic alopecia.


A prescription oral medication for men, it works by inhibiting the conversion of testosterone to DHT, the hormone responsible for hair follicle miniaturization and hair loss. Its use in women is limited due to potential pregnancy risks.

Hormone replacement therapy (HRT) 

For women going through menopause, supplementing with estrogen through hormone replacement therapy can improve hair thickness and health. However, the decision to start HRT should be made after discussing the potential benefits and risks with a healthcare provider.

Oral contraceptives

Birth control pills with anti-androgenic properties can regulate androgen levels in women with androgenetic alopecia or PCOS, helping to reduce the effects of androgens on hair follicles.


An anti-androgen medication that can be particularly effective for women suffering from hair loss due to PCOS or other androgenic conditions. By mitigating the effects of androgens on hair follicles, Spironolactone can help in reducing hair thinning.

Lifestyle modifications

Incorporating healthy eating habits, regular exercise, and stress management techniques into daily routines can support hormonal balance and overall hair health. Additionally, gentle hair care practices and avoiding harsh treatments can prevent further damage to thinning hair.

Support and counseling

Dealing with hair loss can be emotionally taxing. Seeking support from counseling services or joining support groups can offer emotional relief and coping strategies during treatment.

How can I naturally boost hormones for hair growth?

Incorporating a balanced diet rich in vitamins and minerals, managing stress through relaxation techniques, and engaging in regular physical activity can naturally help balance hormones that influence hair growth. Additionally, avoiding harsh hair treatments and adopting a gentle hair care routine can support the health of your hair follicles and promote natural hair growth.

What are the key phases of the hair growth cycle?

The hair growth cycle consists of three key phases: the anagen (growth) phase, where hair actively grows; the catagen (transitional) phase, where hair growth stops and the follicle shrinks; and the telogen (resting) phase, where hair falls out, and the follicle rests before the cycle restarts.

Are lifestyle changes effective in combating hair loss?

Yes, lifestyle changes can be effective in combating hair loss. A diet rich in essential nutrients, regular exercise, and stress management techniques can help balance hormones and improve overall hair health. Additionally, adopting a gentle hair care routine and avoiding harsh treatments can prevent further damage and support hair growth.
