What can be used to permanently change wave patterns in hair?

Chemical solutions are specifically formulated to alter the internal structure of the hair, allowing for a permanent change in wave patterns. These chemicals work by breaking down the disulfide bonds in the hair’s keratin structure. Once these bonds are broken, the hair can be reshaped into a new form, such as waves or curls, and as they are set in this new shape, the bonds can re-form, locking in the new wave pattern.

While heat can influence the texture and shape of hair temporarily (as seen with curling or flat irons), it does not provide a lasting change to the wave patterns in the hair. Water, similarly, can help to temporarily alter a hair’s appearance (such as when wet styling), but it does not fundamentally change the hair structure permanently. Comb styling, obvious as it might be, involves shaping the hair externally and does not change the actual wave pattern permanently either.

Choosing the option related to chemicals underscores the nature of permanent wave changes, emphasizing the science behind how these products effectively reshape and set hair in a new wave formation.
