This measurement is not precise because human hair varies in diameter, ranging anywhere from 17 μm to 181 μm [millionths of a metre] [8] One nominal value often chosen is 75 micrometres (0.0030 in), [5] but this – like other measures based upon such highly variable natural objects, including the barleycorn [9] – is subject to a fair degree of imprecision.

The original hair type chart, also known as the hair typing system, was created by Andre Walker, Oprah Winfrey's hairstylist, in the 1990s. He debuted the system on Winfrey's show to promote his ...
The Andre Walker Hair Typing System, also known as The Hair Chart, is a classification system for hair types created in the 1990s by Oprah Winfrey's stylist Andre Walker. [ 1 ] [ 2 ] [ 3 ] It was originally created to market Walker's line of hair care products but has since been widely adopted as a hair type classification system .

X-rays at 7.3 nm wavelength Lasing in ultra-hot samarium plasma formed by double pulse terawatt scale irradiation fluences. Sub–10 nm X-ray laser, possible applications in high-resolution microscopy and holography. Raman lasers, use inelastic stimulated Raman scattering in a nonlinear media, mostly fiber, for amplification 1-2 μm for fiber ...
Micro x-ray fluorescence (μXRF) is an elemental analysis technique that relies on the same principles as x-ray fluorescence (XRF). Synchrotron X-rays may be used to provide elemental imaging with biological samples. [1] The spatial resolution diameter of micro x-ray fluorescence is many orders of magnitude smaller than that of conventional XRF.
Embracing gray roots has become a trend since the COVID-19 pandemic began, forcing many women to skip their salon appointments. And celebrities have been part of the movement too.
