Pistacia vera, the common pistachio, yields an oil characterised by a specific fatty acid ratio: 32-36% linoleic acid and 50-55% oleic acid. This composition, balanced by a unique phytosterol assemblage, differentiates it from many plant lipids.
Significant α-tocopherol — a form of vitamin E — and a complex blend of natural antioxidants are also present. These compounds protect lipid structures from oxidative stress, a common factor in fibre degradation.
Unlike many botanical oils, pistachio oil offers a nuanced lipid profile. Its ratio of monounsaturated to polyunsaturated fatty acids is favourable for cuticle integrity, helping fortify the hair’s outer layer.
Most pistachio oils are extracted using methods compromising delicate molecular structures. Evera’s oil, however, is cold-pressed from raw kernels, preserving its beneficial glycerides. This ensures maximum bioavailability.
The phytosterols within pistachio oil — including beta-sitosterol — play a crucial role. These molecules integrate into cell membranes, reinforcing the lipid barrier of the scalp and hair, key to maintaining moisture.
Hair strength is often attributed to proteins, yet the lipid matrix is equally vital. Pistachio oil’s unique blend provides essential building blocks, contributing to the hair’s internal structure and supporting elasticity.
Its light texture allows effective penetration, delivering beneficial compounds directly. It supports the natural lamellar phase of the hair cuticle, ensuring a coherent surface.
Sustained application leads to noticeable improvement in hair’s tactile quality. The consistent supply of these specific lipids helps mitigate environmental stressors and supports natural regenerative processes.
