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

Trilostane effectively improved symptoms in dogs with a certain adrenal gland disorder.

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

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

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

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

Liposomes improve drug delivery and reduce skin irritation in dermatology.

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

Protoporphyrin IX is useful in cancer treatment but can cause health problems if not properly regulated.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Turmeric may have benefits for skin health, but more research is needed to confirm its effectiveness.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Different types of stem cells and their environments are key to skin repair and maintenance.

Microneedles help improve skin appearance and deliver skin treatments effectively, but safety concerns need more research and regulation.

Inflammation may be linked to hair loss, and targeting specific enzymes could help treat it.

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

Silver nanoparticles coated with substances like PEG showed strong antibacterial effects and improved wound healing when used in hydrogels.

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.

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

Probiotic bacteria improved skin and hair health in aged mice.

Janus kinase inhibitors are promising treatments for autoimmune skin diseases like eczema and psoriasis.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

Aromatherapy with certain essential oils is a safe and effective treatment for hair growth in alopecia areata patients.

Finasteride exposure in pregnancy causes genital abnormalities in male rats.

Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Finasteride and minoxidil are effective for hair regrowth, while treatments for alopecia areata have varying success and continuous treatment is necessary.

Adult female acne treatment should be personalized, considering individual preferences and pregnancy, using various topical and oral medications while managing side effects and resistance.
