Chemotherapy causes hair loss by damaging hair follicles and stem cells, with more research needed for prevention and treatment.

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

A new microneedle patch made from hair proteins helps regrow hair faster and better than current treatments.

The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

New effective scar treatments are urgently needed due to the current options' limited success.

Telocytes might help with skin repair and regeneration.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Male pattern baldness involves genetics, hormones, and needs better treatments.

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

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

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

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

Too much Smad7 can cause serious changes in skin tissues, including problems with hair growth, thymus shrinkage, and eye development issues.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.

Male pattern hair loss is genetic and influenced by hormones, with treatments like minoxidil and surgery available.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.

No treatment fully prevents hair loss from chemotherapy yet.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Minoxidil and finasteride effectively treat hair loss.

Fat tissue cells are a promising option for healing various diseases, but more research is needed to ensure they are safe and effective.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Hair grays due to oxidative stress and fewer functioning melanocytes.

The HR protein's role as a repressor is essential for controlling hair growth.

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.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Blue light promotes hair growth by interacting with specific receptors in hair follicles.
