The longer the hair stays in the anagen phase, the longer it will grow. During this phase, cells neighboring the papilla in a germinative layer divide to produce new hair fibers, [13] and the follicle buries itself into the dermal layer of the skin to nourish the strand. About 85%–90% of the hairs on one's head are in the anagen phase at any ...
Modelling suggests that enough natural hydrogen exists to meet humanity's demand for hydrogen for thousands of years, however most of this cannot be extracted economically. [ 5 ] [ 6 ] Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.
Hair analysis has the virtue of showing a 'history' of drug use due to hair's slow growth. Urine analysis might detect drugs taken in the past 2–3 days; hair analysis can sometimes detect use as far as 90 days, although certain cosmetic treatments (e.g. dyeing hair) can interfere with this.

Human hair contains melanin which provides dark coloration and protection from UV radiation. Human hair can absorb and emit light across a wide range of wavelengths. The image above depicts melanin autofluorescence at 365-400 nm excitation from a strand of dark brown human hair. A girl with reddish brown hair
Liquid and solid phases can exist in combination at the triple point, a substance known as slush hydrogen. [39] Metallic hydrogen, a phase obtained at extremely high pressures (in excess of 400 gigapascals (3,900,000 atm; 58,000,000 psi)), is an electrical conductor. It is believed to exist deep within giant planets like Jupiter. [38] [40]
