Some hair protein genes evolved early and were adapted for use in hair follicles.

HAIR & SCALP COMPLEX may help treat hair loss by stimulating hair growth and restarting the hair cycle.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

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

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

The review concluded that keeping the hair-growing ability of human dermal papilla cells is key for hair development and growth.

Plet-1 protein helps hair follicle cells move and stick to tissues.

Further research is needed to improve hair regeneration using stem cells and nanomaterials.

TGF-β1 increases androgen receptor activity in hair loss, but Hic-5/ARA55 can counter this effect.

SFRP2 boosts Wnt3a/β-catenin signals in hair growth cells, with stronger effects in beard cells than scalp cells.

Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.

Transplanting melanocyte stem cells from hair follicles can effectively treat vitiligo.

Stem cells from umbilical cords can help regrow hair in mice with hair loss.

Exosomes can help promote hair growth and may treat hair loss.

Immune cells are essential for early hair and skin development and healing.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Activin B improves wound healing and hair growth by helping stem cells move using certain cell signals.

Low-dose radiation affects hair stem cell function and survival by changing their genetic material's structure.

The study concluded that a protein important for hair strength is regulated by certain molecular processes and is affected by growth phases.

Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

Vitamin D Receptor is crucial for hair follicle shrinkage and cell death, affecting hair growth.

Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.

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

A protein from fat-derived stem cells, DKK1, is linked to hair loss and blocking it may help treat alopecia areata.

Sheep hair follicle cells can grow a lot but need the dermal papilla to do so.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.

The hair-growth formula with L-cystine helps protect and grow hair cells.
