Researchers found new hair and nail genes, how hair reacts to UV, differences in white and pigmented hair growth, nerve changes in alopecia, treatments for baldness and alopecia, a toenail condition linked to a genetic disorder, and that nail fungus is more common in people with psoriasis.

A specific chemical change in the S100A3 protein leads to the formation of a four-part structure important for hair formation.

Different sizes of keratin peptides can strengthen hair, with smaller ones possibly increasing volume and larger ones repairing damage.

Scientists made human hair magnetic by coating it with special nanoparticles.

Three genes in Arabidopsis are important for plant growth and development by affecting sugar attachment to proteins.

GALT5 and GALT2 are important for plant growth and development because they help with protein glycosylation.

A specific enzyme is crucial for the bean plant's relationship with certain beneficial soil bacteria and fungi.

Curcumin can be effectively loaded into polystyrene nanoparticles, which are safe for human cells and more biocompatible with curcumin inside.

Genetically modified stem cells from human hair follicles can lower blood sugar and increase survival in diabetic mice.

SLVs help maintain muscle stretch sensitivity and could aid in treating hypertension and muscle spasticity.

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

Transplanted hair follicle stem cells can heal damaged rat intestines.

The new method makes it easier to study the whole cochlea from newborn mice and rats in the lab.

The microneedle patch with quercetin, zinc, and copper effectively promotes hair regrowth for androgenic alopecia.

Ethosomes are a promising method for treating hair loss by delivering drugs directly to the scalp.

Softer hydrogels help wounds heal better with less scarring.

Lack of sleep in mice leads to prostatitis by reducing certain hormones and activating an inflammatory pathway, which can be temporarily fixed with normal sleep.

The new scaffold with two growth factors speeds up skin healing and reduces scarring.

New microspheres help heal skin wounds and regrow hair without scarring.

Transplanted rat hair follicles grew hair and had increased but not fully restored nerve connections in mice.

The new hair loss treatment combining nitric oxide and minoxidil in a special carrier is effective for hair regrowth.

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.

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

Multiphoton microscopy can non-invasively tell apart scarring from non-scarring hair loss and could aid in treatment.

Trichoscopy and trichogram are useful for diagnosing hair and scalp conditions.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

Ablative fractional resurfacing could improve how well topical drugs penetrate the skin, but more research is needed to fine-tune the method.

Sweat glands and hair follicles are structurally connected within a specific layer of skin fat.

Patients with Alopecia areata have fewer specific immune cells that normally regulate the immune system, which may contribute to the condition.
