Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.

New research is helping develop better treatments for alopecia areata.

Multi-pass laser skin treatments improved healing, reduced pain, and had no major complications.

Ziehl-Neelsen's stain helps identify different parts of hair in sheep and goats.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.

The vitamin D receptor is crucial for bone health and affects various body systems, with mutations potentially leading to disease.

MicroRNAs are crucial in controlling cell signaling, affecting cancer and tissue regeneration.

Removing the ATR gene in adult mice causes rapid aging and stem cell loss.

The enzyme steroid sulfatase is linked to breast cancer and other conditions, and inhibitors are being developed for treatment.

Improving artificial vascular grafts requires better materials and surface designs to reduce blood clotting and support blood vessel cell growth.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Fat tissue-derived cells show promise for repairing body tissues, but more research and regulation are needed for safe use.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.

Ectodin integrates BMP, SHH, and FGF signals in developing ectodermal organs.

The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

Hair follicles help absorb and store topical compounds, aiding targeted drug delivery.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.

Researchers created human hair follicles using a new method that could help treat hair loss.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

New effective scar treatments are urgently needed due to the current options' limited success.

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

CDP is crucial for lung and hair follicle cell development.

The new "differential stripping" method effectively measures how much substance gets into hair follicles.

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

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

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

Silver can help prevent and treat infections but its effectiveness varies and should be weighed against costs and side effects.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

Researchers developed promising agents for prostate cancer imaging, with the best one showing high potential for clinical use.
