Bio manages it with treatment.

severely curly

I have very curly and thick hair, so I get really stressed out whenever the rainy season comes.

Even if I straighten my hair well with a straightener in the morning, on humid days it quickly returns to its natural state and becomes frizzy.

It seems like the bio treatment helps reduce stress during the rainy season to some extent.

It seems to calm the hair down and help with damaged hair.
