Androgens have complex effects on hair growth, promoting it in some areas but causing hair loss in others, and our understanding of this is still evolving.

Certain mice without specific receptors or mast cells don't lose hair from stress.

Msx2 and Foxn1 are both crucial for hair growth and health.

Light can turn on hair growth cells through a nerve path starting in the eyes.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Injecting a special gel with human protein particles can help hair grow.

Aconiti Ciliare Tuber extract may help hair grow by activating a specific cell signaling pathway.

Heparan sulfate is important for hair growth, preventing new hair formation in mature skin, and controlling oil gland development.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.

Measuring reproductive hormones in brown bear hair could help identify their sex and reproductive state, but better collection methods or lab techniques are needed.

Women with female pattern hair loss have higher levels of certain androgens, suggesting increased androgen exposure to hair follicles.

The conclusion is that future hair loss treatments should target the root causes of hair thinning, not just promote hair growth.

A pulsed electrical field safely and effectively increased hair growth.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Blocking Wnt/β-catenin signaling with EGF receptor is necessary for proper hair growth.

Red light and LED treatments help hair grow by activating a specific cell signaling pathway.

Ultraviolet rays damage hair, smoking may cause hair loss, and good nutrition is important for hair health, but genetics mainly decide hair thickness.

Houttuynia cordata extract may help hair grow by improving cell survival and increasing cell growth.

Scalp cooling to prevent hair loss from chemotherapy works for some but not all, and studying hair damage markers could improve prevention and treatment.

Good nutrition is crucial for healthy hair and can help with hair loss without medication.

Hair ages due to various factors and treatments like minoxidil and finasteride can help, but more research and better public awareness are needed.

The plant extract remedy Satura® Rosta promotes hair growth and regrowth without negative effects.

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.

Secretome-based therapies could improve hair growth better than current treatments.

A specific enzyme is essential for proper hair follicle stem cell development and healthy skin.

Ishige sinicola, a type of seaweed, may help hair grow by blocking a hair loss-related enzyme and boosting important cell growth.

The conclusion suggests that focusing on certain cellular pathways may improve the prevention and repair of hair loss caused by radiotherapy.

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

Gray hair may be caused by lower antioxidant activity in hair cells.
