Advancements in hair biology include new treatments and tools for hair growth and alopecia.

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

New findings suggest potential treatments for melanoma, hyperpigmentation, hair defects, and multiple sclerosis, and show skin microbiome changes don't cause atopic dermatitis.

The NAMS 2014 recommendations guide healthcare providers on treating health issues in midlife women, emphasizing individualized care and informed decision-making.

Androgenetic alopecia involves genetics, hormones, and can be treated with medications or surgery.

Dermoscopy helps diagnose and monitor treatment for hair loss from scarring conditions like discoid lupus and lichen planopilaris.

Hair usually grows back 1-3 months after treatment for anagen effluvium, and children with Loose Anagen Hair Syndrome often improve by adolescence.

Different women's hair and skin glands respond to hormones in varied ways, which can cause unwanted hair growth even with normal hormone levels, and more research is needed to treat this effectively.

Male pattern baldness involves three mechanisms and finasteride can help reverse it.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

Hair follicle stem cells can turn into various cell types and help repair nerves.

Scientists created a long-lasting stem cell line from human hair that can turn into different skin and hair cell types.

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

Intralesional therapy for keratoacanthoma is effective and has fewer side effects than systemic treatments.

ILK is essential for proper hair follicle development and structure.

Animal models are crucial for learning about hair loss and finding treatments.

Hair in mammals likely evolved from glandular structures, not scales.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Hair absorbs different substances from solutions based on pH levels.

Melatonin treatment increases a specific RNA in goat cells that boosts cashmere growth.

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

PGA-4HGF may help treat hair loss by activating hair growth pathways and extending the hair growth phase.

Recent hair loss research shows some progress, especially in understanding male pattern baldness, but effective treatments for many types of hair loss are still lacking.

STAT3 signaling is important for healthy skin and hair follicles, and its disruption can lead to skin conditions like atopic dermatitis.

The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

Researchers found 617 genes that behave differently in cashmere goat hair follicles, which could help understand hair growth.

UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.

JAK inhibitors help hair regrowth in alopecia areata but have a high risk of side effects.
