Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Hair loss affects self-esteem and quality of life; treatments can help.

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Blood vessels and specific genes help turn cartilage into bone when bones heal.

Stress-related substance P may lead to hair loss and negatively affect hair growth.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

Hormones, especially androgens, play a big role in acne, but most acne sufferers don't have a hormone disorder. Hormonal treatments, including birth control pills, can be very effective for women whose acne doesn't improve with regular treatments.

Children, especially teenagers, can get severe SARS-CoV infection with symptoms similar to adults, but they typically recover well with supportive care.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.

Low-oxygen conditions and ECM degradation products increase the healing abilities of perivascular stem cells.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

5α-reductase inhibitors can cause sexual problems, higher risk of aggressive prostate cancer, and depression.

The dermal regeneration template is effective in skin regeneration, reducing scarring, and has potential for future improvements.

Some heart drugs show promise for other conditions, but more research is needed to confirm their effectiveness and safety.

A new protein was made to detect specific skin cell growth receptors and worked in normal skin but not in skin cancer cells.

High-frequency ultrasonography is a useful but underused tool in dermatology for assessing skin cancers, monitoring diseases, and evaluating treatments.

Some systemic treatments work for nail psoriasis but can have serious side effects.

New findings explain how genetic changes, body clocks, and certain molecules affect tissue response to stress hormones.

The review recommends hormone replacement therapy for women with premature ovarian insufficiency to manage symptoms and protect health, with specific approaches for different groups.

Androgens increase a growth factor in hair cells by creating reactive oxygen species, and antioxidants might help treat hair loss.

Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.

New methods to improve the healing abilities of mesenchymal stem cells for disease treatment are promising but need more research.

Different types of PCOS have different levels of metabolic problems, with the most severe type showing the highest disturbances.
