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.

Mice with human gene experienced hair loss when treated with DHT.

The document concludes that careful evaluation is key to diagnose and treat women with hair loss, with tests for thyroid, iron, and hormones as needed.

Cytokines and neuropeptides are key in controlling androgen levels, affecting skin and hair conditions.

New hair loss treatments may include topical medications, injections, and improved transplant methods.

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 International Society of Hair Restoration Surgery established a curriculum in 2005 to standardize knowledge and skills for treating hair loss, emphasizing it as a multidimensional specialty.

Oxidative stress contributes to hair graying and loss as we age.

Some drugs can cause hair loss, change hair color and shape, or increase hair growth, and treatment may involve stopping the drug or using specific hair growth treatments.

Intermediate hair follicles are a better model for studying hair growth and testing hair loss treatments.

The International Society of Hair Restoration Surgery created a standard curriculum in 2008 to guide doctors in diagnosing and treating hair loss effectively.

Hair loss can indicate underlying systemic diseases and addressing these can sometimes reverse the hair loss.

Chrysanthemum zawadskii extract may help treat hair loss by promoting hair growth and affecting growth factors.

Rare genetic variants in five specific genes are linked to male-pattern hair loss but only account for a small part of the risk.

Female pattern hair loss diagnosis is challenging and should use dermoscopy and histopathology instead of pattern recognition, as hormones may not always be the cause.

Male pattern hair loss is genetic and influenced by hormones, with treatments like minoxidil and surgery available.

Minoxidil treats hair loss, promotes growth, has side effects, and has recent patents.

Treat hair loss with finasteride, minoxidil, or surgery; consider side effects and severity.

Some breast cancer patients developed permanent hair loss after chemotherapy and hormonal therapy, showing patterns similar to common baldness and alopecia areata.
