Merremia peltata leaf extract, particularly the bufotalinin compound, shows potential for treating hair loss.
research A Non-Invasive Hair Test to Determine Vitamin D3 Levels
The hair test for vitamin D could be a useful alternative to blood tests, providing a longer-term vitamin D status, but more research is needed.
research Distribution of polyamines may be altered in different scalp regions of patients with hair loss
Hair loss patients may have different polyamine levels in various scalp areas.
research Establishing and Verifying a Robust Liquid Chromatography-Tandem Mass Spectrometry Method to Simultaneously Measure Seven Androgens Present in Plasma Samples
The method accurately measures seven androgens in plasma and shows different hormone levels in females with acne and obesity.
research Measuring steroids in hair opens up possibilities to identify congenital adrenal hyperplasia in developing countries
Hair steroid measurement is an effective method to diagnose and monitor CAH in developing countries.
research Analysis of hair steroid hormone concentrations at different parts of the head by liquid chromatography-tandem mass spectrometry
