Researchers developed a reliable method to measure testosterone and epitestosterone in urine for medical and anti-doping use.

Cells in hair die by breaking down their DNA and mitochondria as they form keratin.

Bleached hair loses more protein than virgin hair when brushed, indicating more damage.

Researchers created immortal human skin cells with constant testosterone receptor activity to study hair loss and test treatments.

A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.

A new staining method helps tell growing from resting hairs to diagnose hair loss.

Raltitrexed conjugates are less potent than the free drug but more effective at high concentrations.

Sex hormone antibodies can help identify male and female contributors in forensic samples.

Platelet lysate is better than fetal bovine serum for growing stem cells and healing wounds.

Monoclonal antibodies LT-1, LT-2, and LT-7 help diagnose certain blood cancers.

Clear documentation and shared best practices are essential for improving research consistency in pigment cells.

Cell characteristics change with passage numbers, affecting experiment results.

Autofluorescence in hair follicle stem cells can interfere with studies but may help isolate these cells.

Bioengineered skin models aging well, useful for studying aging and testing treatments.

Bioluminescence imaging can track hair follicle cells and help study hair regrowth.

The method can test hair growth products using a lab-made hair-like structure that responds to known treatments.

A new method accurately measures steroid hormones in a few hair strands and could help study chronic stress and hair loss.

A method was developed to grow millions of hair cells from a single hair for research and storage.

3D cell cultures produce extracellular vesicles similar to those in the body.

Overexpressing ornithine decarboxylase and v-Ha-ras in keratinocytes leads to invasiveness and malignancy.

PCR genotyping in cre-loxP mice can be inaccurate due to unintended gene deletions in non-target tissues.

Hair cells grown in a lab showed specific hair proteins.

A new method accurately measures nine neuroactive steroids in small blood samples, helping to study brain diseases.

The photolyase-based device significantly changed the size and heat of potential skin cancer areas in patients.

Storing hair follicles in a special buffer with certain inhibitors can increase hair growth and improve transplant results.

Storing hair follicles in special buffers with added protective substances can increase hair growth and reduce cell death.

Long-lived proteins may predict age-related diseases.

Hair follicles can be used to quickly assess drug effects in cancer treatment.
