Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

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.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.

Eclipta alba extract may help hair grow similarly to Minoxidil.

Terbinafine quickly builds up in skin and hair, staying effective for over 3 weeks.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Modern lifestyles, including poor diet, stress, and long-term use of certain medications, hinder the body's ability to heal from inflammation, leading to chronic diseases.

Rhodococcus equi causes severe pneumonia in young foals, and effective vaccines are needed due to foals' weak immune responses.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

New treatments targeting specific genes show promise for treating keratin disorders.

Formyl-peptide receptor agonists could be new anti-inflammatory drugs.

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

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

Prolactin affects hair growth cycles and can cause early hair follicle regression.

The Wnt/β-catenin pathway is important for tissue development and has potential in regenerative medicine, but requires more research for therapeutic use.

Scientists made the first metal-based compounds from a nonsteroidal antiandrogen drug, which showed potential in fighting both hormone-dependent and independent prostate cancer cells.

Genetics and hormones play a role in male and female hair loss, but more research is needed to fully understand it.

Alpha-hydroxy acids, like glycolic acid, safely improve skin issues and work on all skin types.

NF-κB is crucial for zebrafish heart repair, affecting heart cell growth and repair processes.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.
