Trichoscopic features help diagnose and assess female pattern hair loss severity, with inflammation playing a key role.

Many patients experienced hair loss after COVID-19, with women affected more, starting on average 49 days post-infection.

Skin needs dermal β-catenin activity for hair growth and skin cell multiplication.

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.

Only about 14% of hair follicles can be safely removed in hair transplants without affecting the surrounding area.

Activating Nrf2 in skin cells speeds up wound healing by increasing the growth of certain stem cells.

The study concluded that certain areas of the scalp and beard are safe for hair transplant donor sites in Indian men.

The conclusion is that hair transplant surgery should use microscopically dissected natural hair groupings and some new terms were suggested for clarity.

A new hair loss classification for women improves treatment, but careful patient selection is crucial for successful hair transplantation.

The new hair transplant device reduces damage to hair follicles and makes surgery more comfortable for the surgeon.

Different skin stem cells help heal wounds, with hair follicle cells becoming more important over time.

EGF and KGF signalling prevent hair follicle formation and promote skin cell development in mice.

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

Using a special stem cell formula on the scalp once a month for six months helped people with hair loss grow more hair.

Hairless HRS/J mice resist Bacillus anthracis skin infections due to high numbers of immune cells, not because they lack hair follicles.

Histopathology is not reliable for detecting early fibrosis in traction alopecia or for showing how severe it is.

Dermoscopy helps diagnose different scalp conditions by showing unique signs for each disorder.

CD4+ skin cells may be precursors to basal cell carcinoma.

Skin stem cells can help improve skin repair and regeneration.

The exact identity of skin stem cells and how skin cells differentiate is not fully known.

Skin healing from blisters can delay hair growth as stem cells focus on repairing skin over developing hair.

The study found a specific pattern of uneven melanin distribution on balding scalps that could help understand skin diseases caused by light exposure.

KIF18B is important for correctly positioning cell division machinery in skin cells, affecting hair follicle development.

Skin can heal wounds without hair follicle stem cells, but it takes a bit longer.

Wounded skin cells can revert to stem cells and help heal.

MED1 is essential for normal hair growth and maintaining hair follicle stem cells.

When skin blisters, healing the wound is more important than growing hair, and certain stem cells mainly fix the blisters without helping hair growth.

Hair follicles have a more inactive cell cycle than other skin cells, which may help develop targeted therapies for skin diseases and cancer.

Hair follicles help skin immune recovery after UVB exposure.

Skin cells and certain hair follicle areas produce hemoglobin, which may help protect against oxidative stress like UV damage.
