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.

The Wnt/β-catenin pathway is important for body functions and diseases, and targeting it may treat conditions like cancer, but with safety challenges.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

The Hedgehog signaling pathway is important for skin and hair growth and can lead to cancer if it doesn't work right.

GPRC5D is linked to the formation of hair, nails, and certain tongue areas.

The document explains hair growth and shedding, factors affecting it, and methods to evaluate hair loss, emphasizing the importance of skin biopsy for diagnosis.

Primary cicatricial alopecia, a rare disorder causing permanent hair loss, is hard to diagnose and treat, with treatments like anti-inflammatory drugs and steroids offering varied results and no guaranteed cure. Psychological support for patients is important, and future research should aim to identify causes of the condition.

FGF13 gene changes cause excessive hair growth in a rare condition.

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

RANKL causes lymph nodes to grow by making certain cells multiply.

A substance called epidermal growth factor helps increase the growth of important hair follicle cells by activating a specific cell communication route.

Light therapy can stimulate hair growth and is more effective when started early, but more research is needed on its long-term effects and optimal use.

3D bioprinting improves wound healing by precisely creating scaffolds with living cells and biomaterials, but faces challenges like resolution and speed.

Most hair loss in children is caused by a few common conditions, and it's important to diagnose these properly and support the child's mental health.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

Thyroid hormone receptors are essential for hair growth and wound healing.

Cow placenta extract may help hair grow by increasing a growth factor but is less effective than minoxidil.

Cinnamomum osmophloeum leaf extract may help treat hair loss by promoting hair growth and increasing hair cell proliferation.

The research identified genes and pathways important for sheep wool growth and shedding.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.

Current methods can't fully recreate skin and its features, and more research is needed for clinical use.

FP-1 is a key protein in rat hair growth, active only during the growth phase.

Cholesterol-modified siRNAs targeting certain genes increased hair growth in mice.

Rapamycin reduces skin cell growth and tumor development by affecting cell signaling in mice.

The microneedle device with rapamycin and epigallocatechin gallate effectively promoted hair regrowth in mice.

Tectoridin helps human hair cells grow and makes mouse hair longer, suggesting it could treat hair loss.

Minoxidil can help thicken hair in some people with male pattern baldness, especially if used early and continuously.

A special receptor in sensory nerve endings helps control how they respond to stretching.

Type 2 diabetes slows down skin and hair renewal by blocking important stem cell activation in mice.

Scientists found the best time to transplant human stem cells for hair growth is between days 16-18 when they have the right markers and growth potential.
