Progressive straightening lasts on average 4 to 6 months.
This duration depends on several factors:
• The hair properties of each person (structure, porosity, oiliness, condition).
• Post-application care.
• The characteristics of the hair (the thicker the shorter the duration)
Any that reaches the temperatures indicated for the application and, in particular, irons with a temperature regulator and those with titanium plates are recommended.
Hair should remain loose for the first 3 days to avoid waves. We recommend not putting your hair in a ponytail, wearing headbands or placing your hair behind your ear.
Cold water is best: cold rinsing is recommended, because it closes the hair cuticles, preventing frizz and tangles.
Make sure you don't bathe in hot water, as this opens the cuticle and makes the hair more prone to letting out nutrients and suffering damage.
We do not recommend it, always cut it after the treatment, this way you can better evaluate what type of cut suits you best and you can also cut the dead ends at the end of the treatment to stimulate growth.
