Summary
Hormones significantly influence hair growth, with androgens linked to hair loss conditions like androgenetic alopecia. Other hormones, including estrogens and thyroid hormone, also play crucial roles in hair health and aging.
Area of Science:
- Endocrinology
- Dermatology
- Hair Biology
Context:
- The role of androgens in hair loss conditions such as androgenetic alopecia (AGA) and hirsutism is well-established, leading to targeted therapies.
- Clinical observations reveal that various other hormones, including estrogens, prolactin, thyroid hormone, cortisone, growth hormone (GH), and melatonin, also regulate hair growth.
Purpose:
- To explore the multifaceted relationship between hormonal regulation and hair growth, extending beyond androgens.
- To investigate the impact of diverse hormonal imbalances and physiological states on hair follicle cycling and hair quality.
Summary:
- Androgens are key in AGA and hirsutism, with therapies targeting their metabolism.
- Estrogens, prolactin, thyroid hormone, GH, and melatonin influence hair growth; imbalances can lead to thinning, loss, or hypertrichosis.
- Senescent alopecia, unlike AGA, presents diffusely, prompting inquiry into age-related hormonal decline and its effect on hair aging.
Impact:
- Provides a comprehensive overview of hormonal influences on hair growth, aiding in understanding various hair disorders.
- Highlights the need for considering a broader spectrum of hormones in diagnosing and treating hair loss and related conditions.
- Suggests potential research directions into the role of aging-related hormonal changes in hair senescence.

01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:22Target Cell Response to Hormones
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

01:31Hormones of the Adrenal Glands
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...

01:27Signs of Puberty
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
01:27Major Hormones and Their Functions
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.
