Ученые выявили основную причину вьющихся волос

Выяснилось, что наличие у человека прямых или кудрявых волос напрямую зависит от целого ряда сугубо индивидуальных нюансов строения белков, формирующих их структуру. При этом сам рост волос является следствием формирования новых групп клеток, а совокупность упомянутых выше белков в своей основе контролируется набором генов.

В качестве ключевого фактора, определяющего тип волос, называется характер распределения клеток волоса относительно друг друга в процессе их деления. Если они располагаются достаточно равномерно и линейно, волосы в итоге получают прямую структуру. Изгибы же возникают из-за формирования клеток с различных сторон в очень и очень неодинаковом количестве.

Большое значение имеют также межионные связи, которые вполне могут быть разрушены под влиянием различных кислот или щелочей, зачастую, входящих в состав большинства косметических средств, использующихся, например, для искусственной завивки.

Специалисты также напоминают, что температурное воздействие (в частности, от плойки) также способно разрушать так называемые ковалентные связи, крайне важные для структуры и цвета волос.
