Humans lost body hair relatively recently in evolution.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

Laser device increases hair density, safe for treating hair loss in men and women.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

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

Postpartum depression is linked to changes in brain chemicals, inflammation, stress, and certain genes, and can potentially be identified by markers like specific steroids, serotonin levels, and vitamin D levels.

Some viruses can cause cancer by changing cell processes and avoiding the immune system; vaccines and targeted treatments help reduce these cancers.

RNAi-based biopesticides could be safe and effective for pest control with careful development and risk assessment.

Liposomes improve drug delivery and reduce skin irritation in dermatology.

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

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

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Antibiotics can reduce acne but may lead to resistant bacteria, and understanding the skin's bacteria is important for treatment.

Some vitamins and minerals like vitamin D and iron can help with certain types of hair loss, but more research is needed for others.

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.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

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

TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.

Exposure to finasteride in the womb caused lasting reproductive issues in male rats.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Liposomes could improve how skin care products work but are costly and not very stable.

South Asian women with PCOS are more likely to have metabolic issues and central obesity, and simple measures like waist size and blood pressure can help identify these risks early.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.

The paper concludes that the 1982 criteria for diagnosing systemic lupus erythematosus need updating to improve accuracy and involve dermatologists in the process.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

Interferon, especially alfa interferon, is an effective treatment for cutaneous T-cell lymphoma with manageable side effects.

C60 fullerenes can alter protein function and may help develop new disease inhibitors.

Treating psoriasis on the scalp, nails, and skin folds is challenging, often requiring systemic treatments for severe cases, with some success in topical and biologic treatments.

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

5% minoxidil foam once daily works as well as 2% minoxidil solution twice daily for female hair growth and is more convenient.
