Impact of Hormones on Hair Growth

Hormones are one of many different elements that play a role in the intricate process of hair development. The body produces hormones, which are chemical messengers that control a variety of bodily processes, including hair growth. Hormone imbalances can negatively impact hair health and cause thinning, hair loss, or delayed growth. The effect of Hormones on Hair Growth and how to maintain healthy hair will be covered in this article.

Understanding Hair Growth

Understanding the hair growth cycle is crucial before exploring how hormones affect hair growth. There are three stages in the hair development cycle: anagen, catagen, and telogen. The active phase of hair growth is known as anagen, and it can persist for two to seven years. During the two-week-long transitional stage known as catagen, hair follicles contract and stop growing. In the telogen phase, which lasts for roughly three months, hair follicles are dormant and shed, allowing for the creation of new hair.

Impact of Hormones on Hair Growth

The cycle of hair growth is greatly influenced by hormones, and any hormonal imbalance can cause hair loss or delayed growth. Among the hormones that influence hair development are:

  • Estrogen: A hormone known as oestrogen is generated by both the ovaries and, to a lesser extent, the testicles in females. As it prolongs the Anagen phase of the hair growth cycle and results in long, healthy hair, oestrogen is crucial for boosting hair growth. Nevertheless, hair thinning and hair loss can be caused by hormonal imbalances, such as a drop in oestrogen levels.
  • Testosterone: Male testicles and female ovaries both produce modest amounts of the hormone testosterone. Male sex traits, such as the development of facial hair, are brought on by testosterone. Nevertheless, testosterone can cause hair loss when it is changed into the hormone dihydrotestosterone (DHT). DHT causes hair follicles to shrink, resulting in weaker, thinner hair that finally falls out.
  • Thyroid Hormones: The body’s metabolism and growth are greatly influenced by thyroid hormones. Hair thinning, hair loss, and sluggish hair growth are all possible effects of hypothyroidism, a condition in which the thyroid gland does not generate enough hormones. Hair loss can also be a symptom of hyperthyroidism, a condition when the thyroid gland generates too many hormones.
  • Insulin: The pancreas secretes the hormone insulin, which controls blood sugar levels. A buildup of glucose in the bloodstream can result from insulin resistance, a condition where cells do not respond to insulin due to high amounts of insulin in the body. Inflamed hair follicles might result from this, which can cause hair loss.
  • Cortisol: The adrenal gland produces the stress hormone cortisol. The disruption of the hair development cycle brought on by high cortisol levels in the body might result in premature hair loss.

How to Maintain Healthy Hair?

Diet, lifestyle, and hair care are just a few of the elements that go into maintaining healthy hair. Here are some pointers for keeping healthy hair:

  • Balanced Diet: For good hair development, a balanced diet is crucial. Protein, vitamins, and minerals are all helpful in promoting hair development and preventing hair loss. Meat, fish, eggs, and dairy products are high in protein, whereas fruits, vegetables, and whole grains are high in vitamins and minerals.
  • Proper Hair Care: Regular hair washing and conditioning, avoiding harsh chemicals, and shielding hair from heat damage are all part of proper hair care. Regular hair washing helps to get rid of debris and extra oil, and conditioning helps to keep hair hydrated and stop breaking. Harsh chemicals, like those present in some hair care products, can harm hair and cause baldness. Avoiding overusing heat-styling appliances, such as flat irons and curling irons, and using heat protectant products when using them are two ways to protect hair from heat damage.
  • Manage Stress: Control Stress Stress levels can have a big impact on hair growth, thus controlling them can encourage strong, healthy hair growth. Stress levels can be lowered by partaking in stress-relieving activities like yoga, meditation, or physical activity.
  • Hormonal Management: Hormonal imbalances can be controlled to encourage healthy hair development. To diagnose and treat hormonal abnormalities, seeking medical advice can help to stop hair loss and encourage healthy hair growth.
  • Regular Trims: Split ends, which can result in hair breakage and damage, can be avoided with routine hair trimming. Every six to eight weeks, you should trim your hair to preserve health and encourage growth.


In summary, hormones are essential to hair growth and any hormonal imbalances can negatively impact the condition of hair, causing thinning, shedding, or delayed growth. Having a balanced diet, taking care of one’s hair, regulating one’s stress levels, and getting medical attention for hormonal imbalances are all healthy behaviours that can assist to encourage healthy hair development. Maintaining healthy hair and preventing hair loss is attainable with the right care and management.


  • Can hormonal imbalances lead to permanent hair loss?

Depending on the underlying reason for the hormonal imbalance, hair loss may be transient or permanent. To detect and treat hormonal imbalances and stop hair loss, speak with a healthcare professional.

  • Can hair loss due to hormonal imbalances be reversed?

When the underlying cause of hair loss caused by hormone imbalances is correctly identified and treated, hair loss can be reversed. Hair regrowth may result from treating hormonal abnormalities like hypothyroidism or polycystic ovarian syndrome (PCOS).

  • Can diet impact hair growth?

A balanced diet high in protein, vitamins, and minerals is necessary for good hair growth, hence nutrition can have an impact on hair growth. Foods deficient in critical nutrients can cause hair thinning and loss.

  • Can stress impact hair growth?

Stress can significantly affect hair growth since it can disrupt the cycle of hair growth and cause hair loss. Stress management techniques, such as engaging in stress-relieving activities, can support healthy hair development.

  • Can hair care products impact hair growth?

Hair care products can affect hair development since they can harm hair and cause hair loss if they include harsh chemicals. Healthy hair development can be encouraged by using natural hair care products and limiting the usage of heated styling tools.
