Dermatologists need to understand hair products to treat hair and scalp issues better.

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

Some medicinal plants can help heal wounds and may lead to new treatments.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Zinc is crucial for growth and health in rats.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Estrogen therapy can reduce skin aging but has cancer risks.

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

Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

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.

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

Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.

Adult female acne treatment should be personalized, considering individual preferences and pregnancy, using various topical and oral medications while managing side effects and resistance.

People with PCOS, especially if obese, often have NAFLD, linked to obesity, insulin resistance, and high androgen levels.

KGF and activin are crucial for skin healing and repair.

Liposomes could improve how skin care products work but are costly and not very stable.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

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

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

There are many treatments for permanent hair loss disorders, but their effectiveness varies and there's no clear best option.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

Improving skin barrier and using antifungal treatments can help manage dandruff.

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

The document concludes that specific itchy skin diseases during pregnancy have varying fetal risks and treatments, including corticosteroids and other medications.

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

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Skin problems in COVID-19 patients are rare and may be due to the body's complex immune response or blood clotting issues.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

Researchers found over 40 compounds in Bituminaria bituminosa, including many flavonoids and some with potential for medical and hair care uses.
