Lichen planopilaris and frontal fibrosing alopecia are likely the same disease with different clinical appearances.

Cicatricial alopecia, a permanent hair loss condition, is mainly caused by damage to specific hair follicle stem cells and abnormal immune responses, with gene regulator PPAR-y and lipid metabolism disorders playing significant roles.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

The document suggests that activating autophagy might help with regeneration by removing old and damaged cells.

2011 dermatology discussions highlighted stem cell hair treatments, new lichen planopilaris therapies, skin side effects from cancer drugs, emerging allergens, and the link between food allergies and skin issues.

Researchers found potential new targets for treating melanoma and nonmelanoma skin cancers, and identified a possible cause and treatment for male pattern baldness and eczema.

Accurate diagnosis of cicatricial alopecias requires thorough scalp examination and multiple biopsy techniques.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

Minoxidil and photobiomodulation together improve hair growth better than minoxidil alone.

Hair loss caused by genetics and hormones; more research needed for treatments.

Surgical therapies for vitiligo vary in effectiveness, with combination therapy and medical tattooing recommended for better results.

Stem cells preservation in AGA could be a potential therapy, but more cases needed.

Finasteride helps female-pattern hair loss.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Hair follicles are normally protected from the immune system, but when this protection fails, it can cause hair loss in alopecia areata.

Dandruff is linked to changes in the immune system of hair follicles and skin.

New treatments for hair loss could involve using stem cells and a process called the Wnt/beta-catenin pathway to stimulate hair growth.

PRP shows promise for treating mild alopecia areata but needs more research for cicatricial alopecias.

Fibrosis in the bulge area of hair follicles can cause hair thinning in male pattern baldness, and drugs that inhibit fibrosis might help reverse this.

Lichen planopilaris may be an autoimmune disease causing hair loss due to immune system issues in hair follicles.

Alopecia areata may be treated by restoring hair follicle immune privilege and adjusting immune responses.

iPSC-derived stem cells on a special membrane can help repair full-thickness skin defects.

A new method using Y-27632 improves the growth and quality of human hair follicle stem cells for tissue engineering and therapy.

Excessive sun protection might cause frontal fibrosing alopecia by disrupting skin immune balance.

Hair follicle stem cells are similar to bone marrow stem cells but are better for fat cell research.

Minoxidil nanoparticles significantly boost hair growth in mice compared to regular minoxidil.

Thymic stromal lymphopoietin (TSLP) promotes hair growth, especially after skin injury.

Trichoscopy helps tell apart Frontal Fibrosing Alopecia and Lichen planopilaris by showing different hair and scalp features.

The new method using gene-modified stem cells and a 3D printed scaffold improved skin repair in mice.
