Injections of special skin cells showed potential in treating hair loss, with some participants experiencing increased hair density.

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

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.

Dutasteride and finasteride have equal safety for treating BPH without increased heart risk.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Different types of skin cells play specific roles in development, healing, and cancer.

Melatonin may benefit skin health and could be a promising treatment in dermatology.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Stress-related substance P may lead to hair loss and negatively affect hair growth.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

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.

Cathepsin L is essential for normal hair growth and development.

Low fluence photoepilation temporarily removes hair by targeting the hair follicle's pigmented area without severe damage.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.

The document concludes that understanding the sebaceous gland's development and function is key to addressing related skin diseases and aging effects.
