Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

New treatments for hair loss may target specific pathways and generate new hair follicles.

Retinoic acid helps activate hair growth in people with common hair loss by working on a specific cell growth pathway.

The study suggests that the arrector pili muscle is important for hair health and its damage might contribute to hair loss.

Current hair regeneration methods show promise but face challenges in maintaining cell effectiveness and creating the right environment for hair growth.

SDF-1/CXCL12 and its receptor CXCR4 are crucial for melanocyte movement in mouse hair follicles.

A new treatment using AGED to modulate PPAR-γ shows promise for treating scarring hair loss by protecting and repairing hair follicle cells.

Macrophages are more involved in Lichen planopilaris than in Frontal fibrosing alopecia.

Human skin has multiple layers and functions, with key roles in protection, temperature control, and appearance.

Fat under the skin can help hair grow longer, darker, and increase cell growth.

B-Raf and C-Raf are essential for maintaining melanocyte stem cells to prevent hair graying.

Scientists found cells in hair that are key for growth and color.

Liposomes improve drug delivery and reduce skin irritation in dermatology.

Certain mice without specific receptors or mast cells don't lose hair from stress.

Hair pattern in androgenetic alopecia overlaps with scalp and bone demarcations, with distinct gene profiles affecting susceptibility.

Removing β-catenin in certain stem cells causes hair whitening and pigmentation issues.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.
