Hair loss is a rare but recognized symptom of pemphigus vulgaris, with patients usually regrowing hair after treatment.

Hamilton scale imprecise, hair shaft diameter decreases, stem cell transplant regrows hair, ECP ineffective for alopecia areata universalis.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

Using stem cells from hair follicles to treat female hair loss is safe and effective after six months.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Injecting platelet-rich plasma into the scalp stimulates hair growth, increases hair density, and treats hair loss effectively with minimal side effects.

Scientists identified a unique type of human skin stem cell that could help with tissue repair.

Using extracellular vesicles from stem cells can help hair grow by affecting scalp cells and hair follicles.

Understanding hair biology is key to developing better treatments for hair and scalp issues.

Plucking some hairs can trigger nearby unplucked hairs to grow back more due to a collective response.

Canine hair follicles have stem cells similar to human hair follicles, useful for studying hair disorders.

PPAR-γ agonists like pioglitazone may help manage lichen planopilaris but don't fully reverse scarring.

Blocking Prostaglandin D₂ may help treat hair loss.

New treatments using stem cells and other methods show promise for promoting hair growth in androgenetic alopecia.

Exosomes from stem cells can help regrow hair better than minoxidil.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Bead-jet printing of stem cells improves muscle and hair regeneration.

Exosomes show promise for tissue repair and regeneration with advantages over traditional cell therapies.

Basal cell carcinomas and squamous cell carcinomas have different gene activity patterns, suggesting unique treatment approaches.

Blocking TSLP reduces skin inflammation and cell overgrowth in psoriasis.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

Stem cell and platelet-rich plasma therapies show promise for COVID-19 related hair loss, but more research is needed.

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

Chemotherapy causes permanent hair follicle damage by triggering stem cell loss.

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

Immune activities and specific genes are important in male pattern baldness.
