Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Intramuscular injections improved hair density more than intradermal injections for treating hair loss.

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

New treatments for hair growth and psoriasis may be possible, and gene differences could affect baldness and the severity of skin conditions.

Dexamethasone increases the activity of androgen receptors in human skin cells, which may link it to certain types of hair loss.

Coffee and tea might help hair growth in balding individuals, but side effects and alternative uses are being considered.

Scientists created cell lines from balding patients and found that cells from the front of the scalp are more affected by hormones that cause hair loss than those from the back.

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

Higher caspase-1 levels found in balding scalps; reducing it may help treat hair loss.

Targeting specific genes in certain pathways may help treat male pattern baldness.

Prostaglandin D₂ might be targeted for new male pattern baldness treatments.

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

Prostaglandins may contribute to male hair loss; targeting them could help treat it.

The study found that horizontal sections of scalp biopsies are better for analyzing hair loss, showing fewer hairs and more fine hairs in balding areas.

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

A substance called prostaglandin D2 is linked to stopping hair growth in men with common baldness.

Ginger extracts may help treat hair loss by reducing inflammation and promoting hair growth.

Men with male pattern hair loss have different levels of certain hormones compared to men without hair loss.

Hair transplantation and micrografting, used for baldness, involve moving hair follicles from hair-rich to bald areas, requiring careful procedure and post-care for success.

Minoxidil can cause scalp comedones and acne.

Androgen receptor signaling causes early aging of cells important for hair growth by damaging their DNA.

The document concludes that alopecia has significant social and psychological effects, leading to a market for hair loss treatments.

R-spondin2 may help treat hair loss, gene differences could explain baldness, a peptide's regulation is linked to psoriasis, B-defensin gene copies may affect a skin condition's risk and severity, and potential markers and targets for alopecia areata were identified.

Male pattern baldness involves hormone-related hair thinning, shorter hair, and inflammation.

High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.

Hair transplantation and micrografting are effective for cosmetic facial enhancement, requiring careful technique and postoperative care for successful outcomes.

Rubbing finasteride on the scalp helps with hair loss.

Hair restoration techniques have improved but still rely on limited donor hair, with new methods like cloning and gene therapy being explored.

Early attempts at using cloned cells for hair transplants failed, but 3D cell growth showed some promise.
