The study found that two enzymes linked to hair loss are located in different parts of the scalp, supporting a common treatment's effectiveness.
research Inhibition of rat α-reductases by finasteride: Evidence for isozyme differences in the mechanism of inhibition
Finasteride effectively blocks rat enzymes, but with varying methods and strength.
research Adverse cutaneous reactions to soft tissue fillers – a review of the histological features
Different soft tissue fillers can cause various skin reactions; biodegradable fillers are safer and non-biodegradable ones like silicone can lead to long-term problems.
research Hair Follicle Regeneration Using Grafted Rodent and Human Cells
Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.
research Polymorphisms of the Androgen Receptor Gene and the Estrogen Receptor β Gene Are Associated with Androgen Levels in Women1
Certain genetic variations in the AR and ERβ genes can affect androgen levels in women.
research Transfollicular Drug Delivery: Penetration of Drugs Through Human Scalp Skin and Comparison of Penetration Between Scalp and Abdominal Skins In Vitro
Drugs penetrate scalp skin better than abdominal skin, with scalp hair follicles aiding in higher drug delivery.
research Expression of Calcium-Binding S100 Proteins A4 and A6 in Regions of the Epithelial Sac Associated with the Onset of Hair Follicle Regeneration
S100A4 and S100A6 proteins may activate stem cells for hair follicle regeneration and could be potential targets for hair loss treatments.
research Exosomal Micro RNAs Derived from Dermal Papilla Cells Mediate Hair Follicle Stem Cell Proliferation and Differentiation
Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.
research Insulin Resistance and Skin Diseases
Insulin resistance may contribute to various skin diseases and treating it could improve skin health and prevent more serious conditions.
research Human hair follicles are an extrarenal source and a nonhematopoietic target of erythropoietin
Human hair follicles produce and respond to erythropoietin, helping protect against stress.
research Low sex hormone-binding globulin is associated with low high-density lipoprotein cholesterol and metabolic syndrome in women with PCOS
Women with PCOS who have low SHBG are more likely to have low good cholesterol and metabolic syndrome.
research Topographical and developmental studies on target sites of 1,25 (OH2) vitamin D3 in skin
Vitamin D3 affects cell differentiation in specific skin areas.
