Too much androgen can cause hair loss; finasteride may help.

The document concludes that adenosine receptor agonists have potential for treating various conditions, but only a few are approved due to challenges like side effects and the need for selective activation.

Microneedles improve drug delivery in various body parts, are safe and painless, and show promise in cosmetology, vaccination, insulin delivery, and other medical applications.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

K6hf is a unique protein found only in a specific layer of hair follicles.

Hair loss can significantly affect a person's self-esteem and body image, especially in young people, those who value their looks highly, and women.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

The document recommends using both clinical evaluation and various measurement methods to assess skin greasiness, considering factors like temperature and hormones.

PRP treatment improves hair growth, and the device used can affect results, with some being more effective.

Finasteride effectively blocks enzyme causing male pattern baldness.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

In Italian patients with lupus, the most common skin issue was chronic cutaneous lupus, especially discoid lesions, and nonspecific skin problems occurred in about a third of those with systemic lupus, mainly during active disease.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

The conclusion is that PCOS is caused by ovarian sensitivity to hormones and disrupted hormone control, possibly due to ovarian factors, and more research is needed.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Hair analysis can detect cocaine use but doesn't accurately show the amount or timing of use.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Hibiscus plant extracts may have health benefits like lowering blood pressure and protecting the heart.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

The update highlights that non-classic congenital adrenal hyperplasia is common in women with excess male hormones, requires specific hormone tests for diagnosis, and has various treatment options depending on age and symptoms.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.
