4 Big Hormones of Hair Loss

Hair loss can be attributed to various factors including genetics, stress, and certain medications. However, did you know that there are four key hormones that play a significant role in hair loss? They are testosterone, dihydrotestosterone (DHT), cortisol, and thyroid hormones. These hormones can affect hair growth and cause thinning or balding. In this post, we will dive deeper into the four big hormones of hair loss and how they contribute to this common issue.


Hair loss is a common problem that affects individuals of all ages, genders, and races. While a popular belief is that hair loss is predominantly a cosmetic issue, the truth is that it is often the result of underlying medical conditions and imbalances in hormones. In this article, we will discuss four major hormones that impact hair health and contribute to hair loss. We will also provide insights into how you can balance these hormones to promote healthy hair growth.

Hormone 1: Dihydrotestosterone (DHT)

Dihydrotestosterone (DHT) is a male sex hormone that is responsible for developing male characteristics, such as facial hair and a deep voice. However, when DHT levels are too high, it can cause hair loss in both men and women. DHT binds to hair follicles, causing them to shrink and eventually die. This type of hair loss is commonly known as male-pattern baldness or androgenetic alopecia.

How to balance DHT levels

  • Use a DHT-blocking shampoo or conditioner
  • Take supplements such as Saw Palmetto, Green Tea Extract, or Pumpkin Seed Oil, which inhibit the production of DHT
  • Consult a healthcare professional regarding prescription medication like finasteride to reduce DHT levels

Hormone 2: Estrogen

Estrogen is the primary female sex hormone, responsible for regulating the menstrual cycle and developing secondary sexual characteristics such as breasts. Estrogen also plays a crucial role in hair growth by lengthening the anagen (growth) phase of hair follicles. However, imbalances in estrogen levels can lead to hair thinning and hair loss.

How to balance estrogen levels

  • Use hormone replacement therapy under the guidance of a health professional
  • Incorporate phytoestrogens, like soy products, flaxseeds, and sprouts, into the diet
  • Exercise regularly to reduce stress and balance hormone levels naturally

Hormone 3: Thyroid Hormone

Thyroid hormones (T3 and T4) regulate our metabolism, affecting every cell in our bodies. An imbalance in thyroid hormone levels can lead to hypothyroidism or hyperthyroidism, which can lead to hair thinning and loss.

How to balance thyroid hormone levels

  • Consume more iodine, a mineral necessary for thyroid function that can be found in seaweed, seafood, and dairy products
  • Limit intake of processed foods, which can interfere with thyroid hormone production
  • Consult a healthcare professional regarding medication or hormone replacement therapy if necessary

Hormone 4: Cortisol

Cortisol is a stress hormone that is released by the adrenal glands. High levels of cortisol can lead to a range of health problems, including anxiety, depression, and hair loss. When cortisol levels are high, blood flow to hair follicles is reduced, leading to hair loss and thinning.

How to balance cortisol levels

  • Practice stress-reducing activities, such as yoga, meditation, or deep breathing
  • Exercise regularly to decrease cortisol levels naturally
  • Get enough sleep and avoid overworking yourself


Hair loss is a complex issue, and several factors can contribute to it. By understanding the role hormones play in hair health, we can take proactive steps to balance them and promote healthy hair growth. Be sure to consult with healthcare professionals and follow a healthy lifestyle to keep hair loss at bay.


  1. Can hair thinning be reversed?
    While not all cases of hair thinning can be reversed, taking proactive steps to promote hair health through diet, lifestyle changes, and hormone balancing may help to restore hair growth and prevent further thinning.

  2. How long should I wait before expecting to see results from hormone-balancing treatments?
    The amount of time it takes to see results from hormone-balancing treatment will depend on various factors, including the individual’s hormone levels and severity of the hair loss. On average, it can take several months to notice significant improvements.

  3. Can using hair products contribute to hair loss?
    Using hair products alone typically will not lead to hair loss. However, some hair products’ harsh chemicals and ingredients may damage hair and cause breakage or thinning over time.

  4. Is hair loss hereditary?
    Yes, hair loss can be hereditary. Male-pattern baldness, which is the most common form of hair loss in men, often runs in families.

  5. Is hormonal hair loss more common in men or women?
    Hormonal hair loss affects both men and women, although the patterns of hair loss may differ. Men are more likely to develop male-pattern baldness, while women may experience hair thinning throughout their scalp.
