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

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

YAP and TAZ are crucial for skin cell growth and repair.

Healthy lifestyle changes can significantly improve skin health as you age.

Paris polyphylla saponins may effectively treat acne due to their antibacterial and anti-inflammatory properties.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

Cell aging can be both good and bad for tissue repair.

Animal research has greatly advanced dermatology.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Proxalutamide significantly lowered hospital admissions for male COVID-19 patients compared to a placebo.

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

Vitamin D and calcium are important for skin stem cell function and wound healing.

Different lasers and radiofrequency affect skin differently, important for dermatologists to choose the right treatment.

ATP increases melanin production in skin after UV exposure, with the P2X7 receptor being crucial for this process.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Hair follicles help attract immune cells to the skin during stress.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Apoptosis is crucial for healthy skin and treating skin diseases.

Boron neutron capture therapy for head and neck cancer can cause side effects like mouth sores and skin irritation, which vary depending on where the treatment is aimed.

The conference reported improvements in muscle volume, skin cancer diagnosis, facial and vaginal rejuvenation, and hair growth using various laser treatments.

UV light helped human hair transplants survive in mice without broad immunosuppression.

New UVA-responsive nanocapsules effectively kill microorganisms in hair follicles when activated by light.

Human hair follicles produce and respond to erythropoietin, helping protect against stress.

High androgen levels and genetic factors likely cause Becker's nevus and related symptoms.

Optical imaging and light therapy show promise for diagnosing and treating liver injury caused by surgery.

Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

Low fluence photoepilation temporarily removes hair by targeting the hair follicle's pigmented area without severe damage.

New techniques have enhanced our understanding of how stem cells function and the role of mutations in aging tissues, which may influence future cancer therapies.

Vitamin D3 is important for hair growth and protecting skin from damage caused by long-term sun exposure.

Nanofiber scaffolds help wounds heal by delivering drugs directly to the injury site.
