Hair styling

Temporary formatting

Hair is a fiber rich in keratin, whose behavior depends in particular on its water content and the interactions between its constituents. Moistening it makes it easier to reshape; letting it dry in one position helps maintain that shape. Hydrogen bonds participate in this behavior, but they alone do not summarize all the mechanics of the fiber.

This formatting remains reversible. A new wash or a humid atmosphere can change the hairstyle, because the hair exchanges water with its environment.

The volume is built on several levels

The direction taken at the roots, the length of the strands and the way they group together change the silhouette of the hairstyle. Lifting the roots can give relief, while strands flattened or gathered in bundles reveal more of the scalp. The visual result therefore does not simply correspond to the number of hairs present.

This is why a small amount of product can work better than a generous dose on fine hair. The finish must support the placement without grouping all the material together. If the cut has become too heavy or doesn't leave enough length for the desired shape, changing the amount of styling will only solve part of the problem.

Fixation depends on the formula

Many gels, mousses and sprays use polymers that deposit a film and help hold strands together after drying. The nature of this film influences the hold, flexibility and touch. Waxes and pomades can also shape hair through their texture: not all styling products are based on the same formula.

Sapiens powder contains modified silica and a VP/VA copolymer, according to the composition published by the brand. It combines a texturizing effect with fixation. This helps to understand its use for matte volume, but is not enough to predict your result: the quantity, length and nature of the hair remain determining factors.

Hotter doesn't mean better styled

A 2011 study subjected strands to several drying conditions. Surface damage increased with warmer and closer conditions.

The practical advice is to limit unnecessary exposure: keep the device moving, do not stick it to the strands and use moderate heat. A thermal protectant used according to its instructions can complete the routine, but does not make the hair insensitive to heat. For daily results, it is often more useful to direct the wicks better than to heat more.
