Giving immune serum from vaccinated mice to mice without T cells prevents infection and tumor growth.

The T-zone on the face has more androgen receptors and produces more oil than the U-zone.

Scientists can grow human hair follicle stem cells in a lab without changing their nature, which could help treat hair loss.

Male-pattern baldness might be caused by the effect of hormones on scalp blood vessels.

Finasteride can treat prostatic haematuria, but its use is controversial.

Special and immunohistochemical stains are not routinely needed for diagnosing hair disorders.

DHEA acts like a male hormone on rat skin glands and doesn't turn into female hormones there.

Hyaluronic acid filler injections are a favored non-surgical method to improve facial aging signs due to their convenience, effectiveness, and durability.

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

Transfollicular drug delivery is promising but needs more research to improve and understand it better.

Different treatments can make an aging upper lip look younger and better proportioned.

Mohs micrographic surgery is effective for early-stage non-melanoma skin cancers on the lips, with basal cell carcinoma more common on the upper cutaneous lip and squamous cell carcinoma more common on the lower vermilion lip.

Hair follicles may help teach the immune system to tolerate new self-antigens, but this can sometimes cause hair loss.

Men are more likely to have larger basal cell carcinomas and squamous cell carcinomas, while women have more superficial basal cell carcinomas and tumors on their legs and central face.

Robotics in facial injections offers precision but is costly and lacks personal touch.

IL-36α helps grow new hair follicles and speeds up wound healing.

Maintaining skin health is crucial for overall well-being and involves protecting against environmental damage and using skincare products.

FUE and SMP together can effectively treat hair loss, needing fewer procedures.

T-cell reconstitution after thymus transplantation can cause hair whitening and loss.

Rats have different touch receptors in their paws that help with movement and handling objects.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.

Histopathology is not reliable for detecting early fibrosis in traction alopecia or for showing how severe it is.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Scientists can mimic hair disorders by altering genes in lab-grown human hair follicles, but these follicles lack some features of natural ones.

Papular acantholytic dyskeratosis of the vulva is a rare, benign skin condition that can be managed conservatively.

Wound tension after hair transplant surgery increases with strip size and is higher on the sides, affecting scarring.

Colorimetry can accurately measure hair growth rates in mice.

Conditioned media from mesenchymal stem cells show promise for tissue repair and disease treatment, but more research is needed on their safety and effectiveness.
