Androgens can both promote and prevent hair growth due to differences in gene expression in hair follicles.

Human keratinocytes do not naturally respond to androgens.

Male pattern baldness is caused by certain cells in hair follicles and could potentially be treated by targeting a specific growth factor, TGF-β1.

The 2004 hair research meeting presented new findings on hair cell differentiation, genetic factors in hair loss, hair pigmentation, and potential targeted therapies.

Androgens may cause hair loss by increasing TGF-beta1 from scalp cells, which inhibits hair cell growth.

Hair sensitivity to androgens is partly controlled by specific enzyme expressions in different hair areas.

TGF-β1 from dermal papilla cells suppresses hair growth, and targeting it may help treat androgenetic alopecia.

Antiandrogens have important biological effects, but more research is needed to understand them fully and compare their effectiveness and side effects to other treatments.

Sebocytes play a key role in controlling androgen levels in human skin.

Androgens may block hair growth signals, targeting this could treat hair loss.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

Testosterone affects hair follicles differently across body sites, with beard hair follicles showing more activity of a specific enzyme and presence of androgen receptors compared to scalp hair.

Dihydrotestosterone increases the activity of an enzyme in pubic skin cells that converts testosterone to dihydrotestosterone.

Human skin acts like a hormone-producing organ, making and managing various hormones important for skin and hair health.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Androgens play a key role in hair growth and disorders like baldness and excessive hairiness.

Rat skin takes up and processes testosterone differently than other organs, with testosterone being more important for the skin than its metabolite 5α-DHT.

Androgenetic alopecia, or hair loss, is caused by a mix of genetics, hormones, and environment, where testosterone affects hair growth and causes hair to become smaller and grow for a shorter time.

The exact cause of increased 5α-reductase activity leading to hirsutism in women is still unknown.

Mutations in the androgen receptor gene cause different levels of androgen insensitivity, making it hard to create simple tests for the condition.

The study concluded that both estrogen and androgen receptors, which decrease with age, are linked to skin aging and may be hormonally regulated.

Men with male-pattern baldness have more androgen receptors in their scalp's oil glands, which may contribute to hair loss.

The study created a new method to test drugs that affect hormone processing in skin.

Dermal papilla cells are key for hair growth and could help us understand and treat hair loss.

Biofield Energy Healing significantly increased hair growth by making hair root cells grow more.

Biofield Energy Healing may increase hair growth by enhancing cell proliferation.

Herbal extracts and platelet-rich plasma together may help increase hair growth by making certain cells grow more, through specific cell growth pathways.

Glucocorticoids and sex hormones affect skin health, with potential for targeted treatments to minimize side effects and treat skin conditions.

Exosomes from hair papilla cells and the Chinese medicine Liao Tuo Fang can potentially promote hair growth and could be used to develop hair growth drugs.
