Glossary Hormonal Effects

changes in body functions due to hormone activity

Hormonal effects refer to the changes in the body that occur due to the action of hormones, which are chemical messengers produced by glands in the endocrine system. These effects can influence various physiological processes, including growth, metabolism, mood, and reproductive functions. For example, fluctuations in hormones like estrogen and testosterone can impact hair growth and contribute to conditions such as alopecia.

research Hormonal Effects on Hair Follicles

102 citations , July 2020 in “International journal of molecular sciences”

This review discusses the effects of hormonal changes on hair follicles, concluding that hormones like androgens and estradiol significantly influence hair growth and cycle, while the roles of other hormones are still being researched.

research Significant effects of mild endogenous hormonal changes in humans: considerations for low-dose testing.

30 citations , March 2001 in “Environmental Health Perspectives”

research Significant Effects of Mild Endogenous Hormonal Changes in Humans: Considerations for Low-Dose Testing

2 citations , March 2001 in “Environmental Health Perspectives”

Small hormonal imbalances can cause significant health problems, so more sensitive testing for hormone-disrupting chemicals is needed.

research The effects of ginger (Zingiber officinale) supplementation on the hormonal profile, hirsutism, amenorrhea, dysmenorrhea, and hair loss in women with polycystic ovary syndrome: a randomized double-blind, placebo-controlled trial

May 2026 in “Journal of Functional Foods”

In this study of women with polycystic ovary syndrome, 12 weeks of daily ginger supplementation significantly reduced total testosterone and improved menstrual irregularities compared to placebo, suggesting potential as a natural therapeutic approach, although larger studies are needed.

learn Lavender

Is lavender effective for hormonal hair loss or just stress? No study has tested lavender for stress-related or hormonal hair loss in people; the hair-growth evidence is one mouse study. Case reports link lavender products to breast growth in children, so keep them away from children.

learn Estradiol

Can Estradiol cause side effects in people without a hormonal imbalance? Estradiol can cause side effects even in hormonally balanced individuals.

learn Scalp Micropigmentation

Is scalp micropigmentation suitable for all types of hair loss? Providers say scalp micropigmentation suits many types of hair loss. Some conditions need a diagnosis first, and some can recover or regrow on their own.

learn Hair Transplant

Can women get hair transplants? Some women are candidates for a hair transplant, but diffuse thinning and a thin donor area limit who is suitable. Clinics say a careful assessment of the cause comes first.

learn Follistatin

How does follistatin compare to finasteride or dutasteride for treating androgenic alopecia? Finasteride and dutasteride are prescription drugs with large controlled trials showing they lower DHT and slow androgenic hair loss, at the cost of documented hormonal side effects; follistatin targets a different, regenerative pathway but has only one small phase 1 human trial behind it, so it is experimental with unknown safety rather than a comparable alternative.
