research The effect of relative humidity on the spreading of ethanol on human hair fibers
Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.

This study used Raman spectroscopy and wide-angle X-ray scattering to observe two main α-helix to β-sheet transitions in hair keratin under varying humidity levels, finding that water impacts when these structural changes occur, involving a disordered state.
research Evaluation of hair humidity resistance/moisturization from hair elasticity.
This study found that the PQ-70 shampoo formulation demonstrated the highest Hair Humidity Resistance Factor, indicating superior anti-frizz performance compared to other tested shampoos.
research Fractography of human hair
This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.
research Learning from hair moisture sorption and hysteresis
This study found that the moisture sorption and desorption process can differentiate between cosmetic treatments of hair and provide insights into hair fibre structure changes, with bleaching causing greater symmetry breaking than perming.

1 / 1000+ resultscommunity We are manipulating our hormones, surely it's prudent to track bloodwork ?
The conversation discusses whether individuals using hair loss treatments like Dutasteride (Dut) or Finasteride (Fin) should regularly check their hormone levels through bloodwork. Some argue it's important to monitor the effects of these medications on hormone levels, while others believe it's unnecessary if there are no side effects, citing cost and practicality concerns.
