Cell-based models help test if cosmetic ingredients really work for hair growth and skin health.

Tissue engineering could be a future solution for hair loss, but it's currently expensive, complex, and hard to apply in real-world treatments.

Bio-pulsed stimulation increases production of beneficial vesicles from bird stem cells that improve skin and hair cell functions.

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

New microspheres help heal skin wounds and regrow hair without scarring.

Scientists found a new method using 3D cell cultures to grow human hair which may improve hair restoration treatments.

Researchers created human hair follicles using a new method that could help treat hair loss.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Green tea component EGCG could potentially promote human hair growth.

6-Gingerol, found in ginger, may slow down hair growth and could be used for hair removal.

IGF-1 from human placenta helps hair grow.

The study created a tool that mimics natural cell signals, which increased cell growth and could help with hair regeneration research.

A special mix from certain skin cells can help hair grow by making hair root cells grow faster and activating growth signals.

Adipose stem cell-derived exosomes may improve hair count and scalp health, potentially outperforming current treatments like minoxidil.

Fully regenerating human hair follicles not yet achieved.

Substances from fat-derived stem cells can promote hair growth and counteract hormone-related hair loss by activating a key hair growth pathway.

Red Ginseng Extract may help human hair grow by activating growth pathways and blocking negative effects of certain hormones.

Erythropoietin helps hair grow and could be a potential treatment for hair loss.

Retinoids can change the hair growth cycle by extending the growth phase and shortening the rest phase.

Bovine milk-derived exosomes may improve skin, hair, gut, brain, and bone health.

Minoxidil and ATRA together boost hair growth more effectively than minoxidil alone.

Pulsatilla chinensis compounds may help prevent stress-related hair loss.

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.

Two growth factors, PDGF and FGF2, can potentially be used together to grow enough cells for a hair loss treatment, but their exact function on human cells needs further confirmation.

The new method for isolating stem cells from fat is simple and effective, producing cells that grow faster and are better for hair regeneration.

Adipose Stem Cell-derived Exosomes (ASCE) could potentially be used for hair loss treatment and scalp rejuvenation, as they have shown to increase hair length, thickness, and count, and improve conditions like androgenic alopecia and alopecia areata.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Androgens play a key role in hair growth and disorders like baldness and excessive hairiness.

Hair loss is mainly caused by hormones, autoimmune issues, and chemotherapy, and needs more research for treatments.
