Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

3D-ultrasound can non-invasively detect and predict alopecia areata phases and outcomes.

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

Grafted human scalp samples on mice can produce human hair, useful for studying hair genetics.

Bald areas have lower cell growth, more DNA damage, and increased cell death.

The patch assay can create mature hair follicles from human cells and may help in hair loss treatments.

Frontal fibrosing alopecia on limbs shows permanent inflammatory hair loss, not typical scarring.

Skin conditions like seborrheic dermatitis can make it harder to correctly diagnose hair loss because they can cause the oil glands in the skin to shrink.

Hair shaft malformation contributes to Central Centrifugal Cicatricial Alopecia.

A new method improves the isolation of hair follicle cells for better hair growth research.

A substance called epidermal growth factor helps increase the growth of important hair follicle cells by activating a specific cell communication route.

Skin sheath cells help in hair growth and renewal after birth.

Injecting lab-grown hair cells into the scalp can regrow hair.

Androgenetic alopecia causes hair thinning due to increased androgen activity, treatable with minoxidil and finasteride.

Wnt/beta-catenin signaling in the skin helps fat cell development during hair growth and repair.

A dark-haired Chinese girl had hair that looked banded under certain light but was normal under a microscope.

The study found that the cause of alopecia areata can be identified through tissue analysis, and vertical sections are enough for diagnosis.

Early stage bald spots are linked to skin inflammation and damage to the upper part of the hair follicle.

The flap assay grows the most natural hair but takes the longest, the chamber assay is hard work but gives dense, normal hair, and the patch assay is quick but creates poorly oriented hair with some issues.

The man likely has tufted folliculitis causing painful, scarring hair loss.

A 19-year-old man had a rare skin condition on one side of his face that looked like another skin disease.

Trichoscopy is crucial for diagnosing alopecia areata by identifying specific hair features.

All skin diseases might start in hair follicles.

Frontal fibrosing alopecia may affect nails and could be a type of lichen planus, treatable with certain medications.

A new method using a microfluidic device can prepare hair follicle germs efficiently for potential use in hair loss treatments.

Skin cells can help create early hair-like structures in lab cultures.

Scientists made a mouse that shows how a specific protein in the skin changes and affects hair growth and shape.

The model can effectively test gene functions and drug responses in human skin.

Hair diameter difference, brown skin discoloration around hair follicles, and missing hair in certain areas are key signs of androgenetic alopecia (commonly known as hair loss) when viewed under a dermoscope.
