Growth hormone (GH) is a natural hormone produced by the pituitary gland. It plays a crucial role in growth and development during childhood and continues to support tissue repair and maintenance throughout life. While GH is known to affect various bodily functions, its impact on hair growth is complex and not entirely conclusive.
Research suggests that growth hormone replacement therapy can promote hair growth in individuals who are deficient in the hormone. A study published in Clinical Endocrinology found that GH therapy stimulated body hair growth in men with growth hormone deficiency. However, the effects of GH on hair growth in individuals with normal hormone levels are less clear.
Some studies indicate that GH might actually inhibit hair growth in certain cases. For example, a study published in PMC showed that GH stimulation inhibited human scalp hair follicles ex vivo.
Therefore, while GH replacement therapy can benefit hair growth in individuals with GH deficiency, it's not a guaranteed solution for hair loss or thinning in individuals with normal hormone levels.
It's important to consult with a healthcare professional to determine the appropriate course of action based on individual circumstances and medical history.
